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

Quality Control Program
Rub&Buss measurement Passed
Rub&Buss measurement Failed
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.
