Parameter Descriptions

14. RC Compandor is Always On [0=no 1=yes]

This parameter allows you to indicate whether or not the compandor is

always on.

If this parameter is set to 1 (Yes), the program assumes that the

MSUT’s compressor circuitry is located before the pre-emphasis

circuitry on the transmitter, and behind the de-emphasis circuitry in

the receiver.

With the compandor always “ON” (set to 1), the effects of an “ideal

expandor” are removed from the test results. TEST_15 - RXA Audio

Frequency Response results are reduced in half. Also, the test operator

is not prompted to turn the compandor “ON” and “OFF”.

If this parameter is set to 0 (No), then the test operator will be

prompted to “turn the Radio compandor ON” during testing. Some

manual control of the phone’s compandor state is required.

Example

If you do not want the compandor always on, you would enter 0 as the

value. The value must be either a 0 for no, or a 1 for yes.
