Anritsu understands the requirements of the manufacturers of Bluetooth modules. Test times must be minimized yet performance must be assured. The MT8852B can establish a link with the module under test and perform a comprehensive set of transceiver measurements in under 15 seconds. If the module address is unknown, MT8852B can read it through the module HCI (RS232, USB, USB to RS232 or USB to BLE 2-Wire Adapter), 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.
For fault finding and analysis, BlueSuite Pro3 software is a PC based tool kit that tests EUTs systematically on all channels. BlueSuite Pro3 also graphically displays the essential waveforms of power burst profile, modulation deviation and IQ diagrams. In the early stages of development, the signal generator and transmitter analyzer can be used to test the device without forming any protocol connection to the test set.
Bluetooth interfaces are now standard on many consumer products including digital music players, notebook PCs, gaming handsets, printers, portable credit card readers and headsets. For many manufacturers, it will be the first time that RF measurements have been made in their production environment. The MT8852B is a highly targeted instrument that has been designed to offer Bluetooth test capability in a compact, economical and easy to operate package. The pre-programmed test scripts provide a fast solution that can quickly be integrated into existing production facilities. By using the CombiTest automatic test software, the MT8852B can be quickly integrated into the production flow with automatic archiving of all test results to a database.
Mobile phones are the highest volume product to benefit from Bluetooth technology. In addition to the cellular system, smartphone manufacturers also need to prove performance of Bluetooth technology. For mobile phones without an RF test connector, MT8852B can make all its measurements over the air interface. You simply use your test fixture to position the EUT accurately with respect to the test antenna. Correction values for the path loss at each frequency can be entered into MT8852B path loss table and results are corrected accordingly.
Unigraf UTC-274 supports PD 3.1 protocol, capable of providing a maximum power output of 65W (20V/3.25A) when acting as a Power Source and capable of requesting a maximum 15W (5V/3A) load when acting as a Power Sink. UTC-274 also supports latest PD 3.1 EPR (Extended Power Range) functionality, allowing to test maximum 240W (48V/5A) with an EPU (External Power Unit) both as Source and Sink.
When two Bluetooth Classic devices connect under normal circumstances, they establish a basic frequency hopping scheme across 79 frequency channels in the 2.4 GHz ISM band, hopping at a rate of 1600 times per second. However, as is becoming increasingly common, interference may be encountered in environments where other wireless technologies, such as 802.11 WLAN are also active. Blocked channels, caused by interference, result in a deterioration in the performance of the connection, and this in turn results in poor voice quality or reduced data transfer rates. To limit the impact of this interference, an adaptation of frequency hopping, known as Adaptive Frequency Hopping (AFH) was introduced by the Bluetooth SIG in the Bluetooth Core Specification v1.2 standard. AFH aims to restore the performance of a Bluetooth connection by identifying channels with high error rates and excluding the use of these channels thereafter.
MT8852B Implementation of AFH
When Bluetooth devices that implement the Bluetooth Core Specification v1.2 are connected, each device can create its own Local Assessment Scheme. This is a channel map that defines which channels the device assesses to be clear and which are experiencing interference. The MT8852B is designed to respond to the EUT assessment of which channels are experiencing interference. The MT8852B, being the Central device, creates an Active Channel Map that is the combination of the EUT’s local assessment scheme and any channels that the user has manually masked from the MT8852B user interface.
With the MT8852B-015 AFH Option You Can
• Connect to an EUT using the Bluetooth Core Specification v1.2 faster connection and display the connection time in milliseconds.
• Display the EUT Bluetooth Core Specification v1.2 supported features map, including AFH capabilities.
• Create an AFH connection to the EUT.
• Read the EUT Local Assessment Scheme in the presence of an external interfering signal (e.g. WLAN).
• Manually define additional channels to mask in the MT8852B Pseudo Local Assessment Map.
• Display a graph of channel utilization against time to measure the speed with which an EUT masks channels when an interfering source is activated.
• Display a graph of Frame Error Rate (FER) against time to validate that an EUT identifies all “Bad” channels and maintains a zero or low FER.
• Establish an audio SCO link so that the audio quality can be monitored in the presence of interfering signals, and ensure that the AFH functionality maintains a high quality audio path.
Channel Utilization Against Time
This screen presents a graph with 1 second resolution of the number of channels masked by the EUT. It can be used to measure the time that the EUT takes to respond to the introduction of an interfering signal source. When the interfering source is removed, the same display shows the time that the EUT takes to re-introduce the now clear channels into the hopping scheme.
Frame Error Rate (FER) Against Time
This screen presents a graph with 1 second resolution of the FER of the Bluetooth link with AFH enabled. When an interfering source such as a 802.11 WLAN access point is activated, the FER can be seen to increase immediately. As the EUT’s local assessment scheme identifies the “bad” channels and reports its assessment to the MT8852B, the FER will decrease as the channels are removed from the hopping plan.
Audio Measurements with AFH
The MT8852B also supports SCO connections with AFH active. This facilitates analysis of the impact of an interfering source on the quality of an audio signal.
