Bluetooth
Headset Solution
Microtronix Systems Ltd., a manufacturer
of telephone test systems since 1972, now provides a Bluetooth Headset
test solution. The system architecture allows the test system to
automatically discover the bluetooth link to the Bluetooth Headset.
The fast and seamless connection protocol (Bluetooth HSP profile)
incorporated into the test system allows the customer to quickly
test their product in production or quality assurance environments.
|
|
The bluetooth test
solution utilizes the technology from the IP Phone test system
platform. Direct Digital Generation to communicate with the
headset, without the need for analog signalling provides high
speed, accurate and repeatable test results on the headset. |

The Microtronix Controller
Unit contains a test program or test script that specifies the
limits and test sequence for the headset under test. Using a
bluetooth transceiver connected to the USB port, Microtronix
software creates a seamless connection to the bluetooth headset
during the discovery mode. Microtronix test equipment easily
interfaces to a Head and Torso Simulator or a custom fixture
can be developed for your needs.

Microtronix software for the
Controller Unit to communicate with Bluetooth Transceiver. This will allow audio signals IN/OUT for
measurement for Bluetooth Headset
|
Making a Connection
The test system will
prompt the operator to start the pairing process
of the headset. This creates a unique wireless
link between the test system and the headset.
Once a successful link has been made, the
test
system will display the Bluetooth logo  on
the screen.
|
Test Script Changes
The test scripts or test programs contain the limits,
signal levels and sequence of tests for the device
under test. The end user can modify these parameters
using the Test Program Editor (TPE) for WindowsTM
software package. |

Summary
Collector: The Summary Collector Program
automatically collects and stores the summary reports
to your disk drive or local area network. |

Multi-tone Frequency Response
The Multi-tone Frequency Response feature provides
increased testing speed in a production environment.
The user can program the number of frequencies to
use during a burst. A typical frequency response
is performed in two seconds. Headsets using DSP
technology or CODECs can take advantage of this
feature to ensure the signals are properly transmitted.

Audio
File Play and Record
The Audio File Play and Record option provides
the ability for the tester to play an audio file through
the Artificial Mouth and make a recording of the received
signal at the artificial ear. |
| |
| |
Spectrum
Analysis
The Spectrum Analysis software provides the ability
to play an audio file through the Artificial Mouth or
Ear similar to the Audio File Play and Record option.
DSP analysis techniques of the audio files allows the
system to display a frequency response. |
