The Perfect Test & Measurement Partner
MT8852B

Qualified by Bluetooth® SIG for Measurements

The Anritsu MT8852B Bluetooth® Test Set is the market leading RF measuring instrument for design proving and production test of a wide range of products that integrate Bluetooth® technology, including; phones, headsets, computers, audio-visual and gaming products as well as modules. In production, a single key press initiates a measurement script that tests a device in less than 10 seconds.

The MT8852B Bluetooth® Test Set is compliant with Bluetooth® 1.2, 2.0, 2.0 + EDR, 2.1, 2.1 + EDR, 3.0, 3.0 + HS, 4.0 core specifications


Measurements Performed as Defined in the Bluetooth® RF Test Specification and also User Definable

As members of the Bluetooth® Special Interest Group (SIG) since 1999, Anritsu has actively participated in the development of the standard from the first 1.0 core specification release through to the current 4.0 core specification release. The MT8852B Bluetooth® Test Set builds on this experience to offer an optimized radio layer test instrument.

The MT8852B Bluetooth® Test Set gives you a one-button test to fully characterize your Bluetooth® implementation and ensure that your reputation for quality is maintained. Therefore you can ship products to your customers with confidence that they will work perfectly first time, every time.


Fast Comprehensive Transceiver Measurements: < 10 seconds

mt8852b_signaling.jpg

The MT8852B can establish a link with the module under test and perform a comprehensive set of transceiver measurements in under 10 seconds. If the module address is unknown, MT8852B can read it through the module HCI (RS232 or USB), or perform an Inquiry. An integrated CW frequency counter can be used for crystal trimming. Module testing requires a test fixture, ideally in a shielded box, to interface the Bluetooth® module to the MT8852B. The test fixture should provide a direct RF connection plus, if required, connection to the module's HCI interface.


Option for Bluetooth® Low Energy Measurements (BLE)

mt8852b_ble.jpg

There are 2 types of Bluetooth® low energy devices, Dual Mode devices integrate Basic Rate, EDR and low energy functionality into a single chip while Single Mode devices support only the low energy standard. Mobile phones and PCs are expected to support the Dual Mode devices and sensors and peripherals will only support the low energy standard.

The MT8852B, with Option 27 - Bluetooth® Low Energy Measurements, sends these test controls to the DUT to deliver fully automated testing. With the use of this integrated interface, the MT8852B can run a single test script that with a single key press can test the Basic Rate, EDR and low energy performance of a DUT.

For DUT transmitter tests, test controls sent from the MT8852B configure the low energy device to transmit test reference packets that are captured and analyzed by the MT8852B receiver.


Option for Adaptive Frequency Hopping (AFH) Software

mt8852b_mobile_phone.jpg

Manufacturers need to prove the performance of both the Bluetooth® and mobile phone radios. Test is typically a bottleneck in any mobile phone production line and so testing the Bluetooth® interface must be performed with no increment to total test time. It is also vital to confirm that both radios can be active simultaneously without any interference between them.

Should the phone also include an 802.11b/g WLAN radio, the AFH feature of the MT8852B is ideal for validating that both radios can be used simultaneously without mutual interference. This option provides graphical displays of FER and masked channels when interfering signals are introduced, allowing optimization of hardware designs.

Support 3 SCO Channels with CVSD, µ-Law and A-Law Air Interface Audio Measurements

The MT8852B offers comprehensive testing facilities integrated within a Bluetooth® wireless technology test set. Rear-panel jack-plug connectors provide analog inputs and outputs for all three audio channels.


Start Testing Immediately with BlueTest2 Production Line Software

mt8852b_bluetest2.jpg

Anritsu has developed the BlueTest2 software to increase the efficiency of Bluetooth® testing on the production line. The software provides a remote means to control and run Bluetooth® tests on up to 16 MT8852B units simultaneously. This simultaneous connection not only means that tests can be performed quickly and easily, but also that script and configuration settings can be copied between the test sets in the line.

BlueTest2 software is supplied as standard with MT8852B in both executable and source code formats (Visual Basic.NET). Users may edit the BlueTest2 source code in order to add functionality to customize it for specific requirements.

BlueTest2 functions includes:


  • Run Bluetooth® tests remotely using up to 16 MT8852B test sets
  • Copy settings from any of the test sets to BlueTest2
  • Apply settings from BlueTest2 to all of the test sets in the line
  • View and print detailed reports of the tests conducted

MT8855A

Frequency Coverage from 20 Hz to 20 kHz

The MT8855A is the world's first test set designed specifically to perform high-quality audio measurements on products using the Bluetooth® Advanced Audio Distribution Profile (A2DP), the Headset profile, or the Hands-Free profile.

The MT8855A is the ideal instrument for both design validation and manufacturing test. Typical Bluetooth® products that can be tested with the MT8855A include stereo and mono headsets, mobile phones, digital music players, integrated and accessory car kits, and desktop speakers. Accessory microphones and speakers connect directly to the MT8855A's audio inputs and outputs to enable the development of a complete test system. Module testing is also facilitated using direct connection to the RF and audio connectors.

After establishing a Bluetooth® connection with the DUT, the MT8855A's integrated audio generators and analyzers are used to perform measurements including level, frequency response, and THD+N.


Start Testing Immediately with BlueAudio Production Line Software

mt8855a_blueaudio.jpg

BlueAudio software, supplied with each MT8855A, is installed on a PC that connects to the MT8855A using a standard USB cable. BlueAudio serves as the MT8855A's front panel and is used to configure the instrument and display graphical and numeric measurement results.

Configuring the MT8855A for testing is a simple, four-step process.


  • Define the Bluetooth® profile and the role of the MT8855A, e.g., A2DP Source
  • Define the Bluetooth® connection process, e.g., Inquiry with Authentication
  • Select the audio inputs and outputs, e.g., microphone input and speaker output
  • Select the measurements to be performed, e.g., THD+N and frequency response

For R&D applications the Manual Test mode provides full graphical results, whilst an Auto Test mode is available for rapid and repetitive production testing with user configurable test plans, results archiving and report generation.


A2DP Profile Support for Stereo Headset Testing

mt8855a_a2dp.jpg

Stereo headsets running the A2DP or Hands-Free profile are now a common wireless device for use with mobile phones and digital music players.

For headset speaker testing, a test fixture that couples the headset speakers to the test system's microphones is integrated into a shielded enclosure. The MT8855A's built-in microphone power supply allows for direct connection of the accessory microphone without the need for additional amplifiers or power supplies. A frequency response curve supplied with the microphone, corrects headset speaker measurements, specifically to provide accurate audio level measurements.

The response of the DUT can also be compared with a stored "Golden Trace" for comparative measurements. These tests validate the performance of headset DAC, amplifiers, and speaker cones.


Headset and Hands-Free Profile Support for Mono Headset Testing

mt8855a_hsp_hfp.jpg

To test the headset microphone and audio input stages, the MT8855A plays an audio test signal through the accessory speaker coupled to the target microphone. Speaker frequency correction curves can again be applied to eliminate the response of the speaker from the results of measurements.

The MT8855A decodes the audio tone received over the Bluetooth® connection and processes it to generate the audio measurement results. The recovered tone can be routed to the integrated speakers or to a headphone jack plug for use in rapid functional testing.


Dual Channel Audio Generator and Analyzer for Stereo (Left/Right) or Mono

mt8855a_module.jpg

The MT8855A is ideal for use in evaluation and validation of new product designs and reference modules. During design evaluation, audio measurements are made with direct cable connections between the MT8855A and the DUT. When using cables to connect directly to the MT8855A Line Input and Output, transducers, such as microphones and speakers, are excluded from the test configuration. This set up offers the greatest dynamic range for distortion and frequency response measurements.


SCO/eSCO Connections for Testing Modules Without Profile Support

For modules that do not support audio profiles, measurements can be performed using a SCO/eSCO connection only.


Fast Measurement Speed: < 15 seconds for Typical Headset

The total test time for a 5 point frequency response plus 997 Hz THD+N, stereo separation, and stereo phase (including inquiry and connection time but excluding handling time) is typically less than 15 seconds.

MT8860C

A Fully Integrated WLAN Measurement Solution for Design and Production

The Anritsu MT8860C is the only WLAN Test Set with Network and Direct modes for testing devices that conform to IEEE 802.11 standards.

The MT8860C is an integrated one-box test set dedicated to testing 802.11 WLAN devices. It provides a high-speed measurement solution that is ideally suited for design proving and production testing. The MT8860C replaces existing test systems that typically utilize power meters, spectrum analyzers and gold radios with external attenuators.

The end result is a test instrument that is easier to integrate into production, provides traceable and repeatable measurements and offers a universal solution for all WLAN chip sets. By being simpler to maintain and calibrate, the MT8860C also reduces test system costs, increases production throughput and delivers the most flexible WLAN test system.


One Test Set, Two Modes of Testing (Network and Direct Mode)

The MT8860C provides two modes of operation: Network and Direct. In "Network" mode, standard WLAN signaling is used to test both the transmitter and receiver of a device under test (DUT). In "Direct" mode, the MT8860C tests the DUT receiver by automatically creating and transmitting WLAN packets, and measures the DUT transmitter by using a built-in transmitter analyzer.


Network Mode Allows Devices to be Tested in a Connection using Standard WLAN Signaling

Network mode greatly simplifies the measurement set-up and allows any WLAN device to be tested in a mode that closely reflects its native operation. The MT8860C built-in reference radio simulates both an Access Point (AP) or client device/station (STA), and using standard protocol messaging, establishes a network connection with the DUT. Once a connection is made, both the transmitter and receiver of the DUT can be tested without the need for control software from the chipset vendor.


Network Mode transmitter testing

mt8860c_network_tx.jpg.jpg

When testing the transmitter characteristics of a WLAN device, data frames containing address information that is specific to the DUT are transmitted by the MT8860C. The DUT responds by transmitting frames back to the MT8860C. The frames returned by the DUT are then captured by the MT8860C built-in transmitter analyzer. The MT8860C can be configured to capture and analyze data or acknowledgement (ACK) frame types.

Network Mode receiver testing

mt8860c_network_rx.jpg.jpg

For receiver sensitivity testing, the MT8860C transmits packets at power levels down to 100 dBm. For each packet correctly received, the DUT responds by transmitting an acknowledgement (ACK) packet. By counting the number of ACKs, the MT8860C is able to calculate the Packet Error Rate (PER). The use of a reference radio allows testing to be performed at different data rates with real-time configuration of the packet structure, including MAC address and payload length.


Direct Mode allows WLAN Devices to be Tested with the Support of Control Software from the Chipset Vendor

In Direct mode, the MT8860C acts as a transmitter analyzer and WLAN signal source. This mode of operation is most similar to the test method that uses spectrum analyzers, power meters and gold radios for device testing. Control software supplied by the chipset vendor is used to configure the DUT via a host processor interface. Testing of the WLAN transmitter and receiver is performed by the MT8860C without a network connection being established.


Direct Mode transmitter testing

mt8860c_direct_tx.jpg.jpg

The WLAN device is configured to continuously transmit packets. The MT8860C built-in transmitter analyzer is configured to trigger on the incoming packets and performs all the selected transmitter measurements in parallel.

Direct Mode receiver testing

mt8860c_direct_rx.jpg.jpg

When testing the RX sensitivity of a device in Direct mode, the MT8860C is configured to transmit a specified number of data packets. After the final packet has been transmitted, a baseband register (internal to the DUT) is read. This register contains the number of packets received without error. The PER is then calculated from the number of packets sent by the MT8860C and the number received without error.

When testing a receiver in Direct mode, it is not possible to use LANLook for automated PER measurements or receiver sensitivity searches.


Built-in Reference Radio for Calibrated Packet Error Rate (PER) Measurements

The MT8860C integrates a reference 802.11 transmitter and receiver. It provides a single calibrated test port for both transmitter and receiver testing. The integral reference radio does not suffer the drift and variability of existing gold radios, resulting in more stable test systems and improved quality of output.


LANLook Software for Instrument Configuration and Results Display

LANLook runs on a standard PC and uses a conventional Windows® based interface for both instrument configuration and control. Measurement results are displayed in clear numerical and graphical formats. LANLook communicates with the MT8860C using remote commands that are sent via a GPIB or Ethernet interface.


Validated by the Wi-Fi Alliance® for Wi-Fi® CWG Certification Testing

The wireless market is seeing a significant increase in the number of converged handset devices that incorporate both cellular and Wi-Fi® functionality. Due to the many potential applications and deployment scenarios that converged devices may ultimately function in, it is important for network operators and handset vendors to have a consistent method of evaluating and comparing the RF performance of converged devices.

To address this requirement, the CTIA and Wi-Fi Alliance® have jointly developed a CWG (Converged Wireless Group) RF Test Plan that;

  • Defines the test methodology for the RF performance evaluation of Wi-Fi® mobile converged devices
  • Specifies the test conditions for each of the conducted and radiated tests defined
  • Allows any Wi-Fi mobile converged device to be tested in a mode that closely reflects its native operation

MT8870A

Suitable for Non-signaling Testing of Smartphone and Chipset Module

The MT8870A Universal Wireless Test Set has been specifically designed for the high volume manufacturing test of all common cellular and short range wireless technologies. An MT8870A instrument mainframe can contain up to four MU887000A/01A TRx test modules, each capable of independent control by an external PC. Each module has an integrated Vector Signal Generator (VSA) and Vector Signal Analyzer (VSA) to perform both Transmitter and Receiver RF tests, including both Analog and Digital Audio Analyzer.


All-in-one Platform Accommodating 4 Test Modules

mt8870a_modular.jpg

Up to four measurement modules can be installed in one main frame and each module can be controlled independently. The four installed modules share the same power supply, chassis, and internal bus interface, helping cut infrastructure costs.


Lower Cost of Test, Smaller Footprint and Cuts Line Downtime

With four TRx modules installed in one MT8870A main frame, the shared power supply, chassis, internal communications bus, remote controller, reference frequency oscillator, software license, etc., cut capital costs.

Whereas easy module swap-out cuts line downtime without having to send the whole unit for repair and an immediate changeovers takes only minutes.


Four Test Ports per Module (2 Full-duplex and 2 Half-duplex OR 4 Full-duplex)

mt8870a_ports.jpg

Each MU887000A/01A TRX Test Module has two full-duplex and two half-duplex RF connectors.

The full-duplex ports incorporate dividers at the front end to support simultaneous tests in both TX and RX directions when testing typical wireless standards.

The half-duplex ports incorporate switches at the front end to switch between each test port when used either for TX or RX tests. These half-duplex ports have higher sensitivity than the full-duplex ports and are ideal for low-level wireless signals.


Shared Software License and Easy Software Expansion

mt8870a_license.jpg

The TX measurement software packages and waveforms can each be licensed separately. One license can be used for up to four TRX test modules, cutting test equipment costs. A TX measurement software package is required for TX tests for each communication standard and a waveform is required for RX tests.

Since hardware specifications are shared by all MU887000A/01A TRx modules, new standards are easily supported by adding software licenses.


Fast Measurements Independent of External PC

mt8870a_mu887000a.jpg

The Dual Core CPU, DDR3 memory and fast PCIe bus in each MU887000A/01A TRx Test module assure fast measurements independent of the external PC.

Rx test waveforms can be preloaded into 4-GB ARB memory, cutting reload times when switching wireless standards.


Wide Frequency Range from 10 MHz to 6 GHz (Option MU887000A/01A-001)

To provide future-proof frequency-band extendibility, the frequency band covers a wide range from 10 MHz at the lower end to 6 GHz (option) at the upper end.

The wideband (10 MHz to 6 GHz) signal generator and signal analyzer support easy and smooth extendibility for new wireless standards, unlike dedicated test set supporting only specific frequencies.

Note: Standard TRx module operates from 10 MHz to 3.8 GHz


160 MHz Measurement Bandwidth comes as Standard

The MU887000A/01A TRx Test Module is able to perform RF transmitter / receiver testing of the latest WLAN standard 802.11ac wireless modules

Usually, upgrading bandwidth requires extra costs for changing instruments, adding options, etc., but since the MU887000A/01A has a 160MHz wide bandwidth as standard, these extra costs are unnecessary.


Support All Assorted Cellular and Wireless Standards Test

The MU887000A/01A TRx Test module is able to support the RF (PHY) testing of both cellular (LTE, W-CDMA, GSM etc.) and Short Range Wireless (WLAN and Bluetooth®) receivers and transmitters.

Supported Standards:

  • LTE-FDD
  • LTE-TDD
  • W-CDMA / HSPA
  • TD-SCDMA
  • GSM/EDGE
  • CDMA2000®

  • Bluetooth®
  • GPS, GLONASS and BeiDou
  • FM and DVB-H
  • ISDB-T and ISDB-Tmm

Simultaneous Measurement of 4 Devices and Parallel Measurement of Multiple Wireless Technologies

mt8870a_parallel.jpg

With four modules installed in the MT8870A, four test devices can be connected and measured in parallel simultaneously. Different technologies can be measured in parallel, helping reduce both measurement times and line test equipment footprint.

For example: Two TRx Test Modules can be used to measure multiple wireless technologies in one smartphone. The multiple antennas for the various wireless technologies in the smartphone are connected all at one time to execute measurements in parallel, greatly reducing the problems of moving smartphones between test stations and re-booting time for smartphone.


Comprehensive MIMO Measurement Solutions

mt8870a_mimo.jpg

The MT8870A is ideal for performing streaming measurements from each antenna under conditions closely mimicking a real usage environment at the R&D and design stages. There is no need for troublesome external cable connections, because the timing of each MU887000A/01A unit and the 10-MHz reference frequency are synchronized by the internal connections, offering easy True MIMO measurement.


mt8870a_mimo_chart.jpg

Audio Analyzer and Audio Generator in Each TRx Module (Option MU887000A/01A-002)

By using FM TRx measurement capability, the built-in audio analyzer / generator is available to perform audio signal measurements. Support mono audio and stereo audio with analog interface or digital interface helping reduce the equipment footprint for wireless module manufacturing.
