Here are the specifications of the new version:
* The program works with the Audio Analyser ATB 701
* The program includes the comfortable ATB 701QC program
* Setting of the definition without script, there is no need of learning to program
* Tolerance field is easy to set automatically or with the mouse
* Rub&Buss is tested with the signal 13 to get a nonlinear distortion measurement
* Surrounded noise does not disturb the Rub&Buss measurement because of the Q-Index calculation

Measurement functions
1. Total Harmonic Distortion THD
2. Intermodulation Distortion, IMD
3. Frequency response(SPL)
4. Impedance(IMP)
5. Polarity Test
6. Thiele-Small Parameter
7. Phase
8. Step response
9. Quality Control Program

1. Frequency response
The frequency response is tested with the M-PN signal. The measurement with this periodic noise gives the highest accuracy. The tolerance mask can be set automatically or manually.

2. Rub&Buss measurement
The Rub&Buss is tested with the signal 13. The signal 13 consists of two sine-sweeps with the frequency ratio of 1 : 1.3. This signal is showing all resonances of the unit under test.
For the passed and failed decision the Q-Index is calculated. The index is calculated from all frequencies higher than the second frequency of the test signal 13. The account is set into proportion to the amplitude of the test signal. The best speaker has the highest Q-index.
The Rub&Buss measurement has following tests.

Calculation of error
1. THD, K2,K10 The test is for the controlling of the placement of the voice coil.
2. IMD The test is for the controlling the gluing, loose particle and if there are cone touching of connection wires.
3. Frequencies > K5 The test is for the controlling of voice coil rubbing the magnet.
3. Distortion THD Test
The THD test tests the harmonic distortion. The test signal is a sine wave with frequency to select. Because this test is included in the Rub&Buss test it is only for the special demand of the manufacturer. In the definition there is to set the maximum THD and the frequency.
4. Polarity Test
The polarity test is for testing the wiring. It is for speakers, headphones and microphones. The test signal is a half sine wave. In the time response the program calculates if the positive or negative amplitude is the greatest value.

Satellite Phone Indoor Amplifier Device (Inmarsat & Thuraya Suitable)

The Satellite Phone Indoor Amplifier Device is a device let your Inmarsat or Thuraya satellite phone can normally use in the room. (used in the boat, vehicle, building etc). Install this device with our special outdoor antenna and omni indoor antenna, making you keep in touch with others freely even in the room, you can call out and receive the incoming call even in the room, no need go out to search the satellite signal and wait for register, and at same time, the device can support up to 100 sets satellite phone communication at same time in the room which cover up to 120 square meters.

The basic principle of this device is that the outdoor antenna receives the downlink signal from the satellite (Inmarsat or Thuraya), through high selectivity band-pass filter to well isolate the passband signal, after amplifying by integrative power amplifier, then transferred by indoor antenna, meanwhile, on the way of uplink path, signal of satellite phone in the coverage area is transmitted to the satellite after disposing by uplink amplifying link path by same working mode.
For the Inmarsat and Thuraya satellite network system, downlink signal including: satellite and GPS L1 2 signal. The device has Automatic Level control ( ALC )System, automatic control the gain according to the circumstance.

Features:
-Keep your Satellite phone on communication status even in the room. Avoid miss coming call when you are in the room. And also you no need going outdoor for searching the satellite signal.
-The device can suitable for Inmarsat Isatphone Pro, Thuraya SO-2510, SG-2520, Thuraya XT etc models, and also GPS.
-Keep your satellite phone can move freely, unlike Fixed Satellite phone which canâ??t move, and also you can freely hand carry your satellite phone when need go out.

Application Range:
Boat driving room;
Emergency Vehicles;
Remote mine;
Earthquake or other emergency response administration;
Remote country where there dont have GSM mobile phone signal areas.
