This section lists the specification limit names and explains how each is used. For instructions on changing the pass/fail limits and saving the changes to an SRAM card, see “Changing Pass/Fail Limits” on page 106 and “Saving/Deleting a Procedure” on page 109.

1.AMPS Data Peak Deviation

Enter the upper and lower deviation limits, in kHz.

The 1004-Hz test signal in the Base Station is sent to the data modulator in the radio and the Test Software measures the resulting peak deviation and compares the result with the limits.

2.AMPS Deviation at -16 dBm Audio Level

Enter the upper and lower deviation limits, in kHz.

The 1004-Hz test signal in the Base Station is set to a level of -16 dBm, and is then sent to the analog modulator in the radio. The Test Software measures the resulting deviation and compares the result with the limits.

3.AMPS Deviation at 0 dBm Audio Level

Enter the upper deviation limit only, in kHz.

The 1004-Hz test signal in the Base Station is set to a level of 0 dBm, and is then sent to the analog modulator in the radio. The Test Software measures the resulting deviation and compares the result with the limit.

4.AMPS Distortion at -16 dBm Audio Level

Enter the upper distortion limit only, in percent (%).

The 1004-Hz test signal in the Base Station is set to a level of -16 dBm, and is then sent to the analog modulator in the radio. The Test Software measures the resulting distortion is compares the result with the limit.

5.AMPS Frequency Error

Enter the upper and lower limits, in Hz.

The Test Software measures the transmitter center frequency and compares it with the ideal frequency, based on the entry for channel number. The difference between the two is the frequency error. The Test Software then compares the calculated frequency error is then compared with the limits.

6.AMPS Residual FM [15 Hz - 15 kHz] Enter the upper and lower limits, in Hz.

With all modulation turned off, the Test Software measures the amount of FM present in the rf carrier from the radio.
