Test Descriptions

TEST_05 - TXA Modulation Deviation Limiting

Parameters Used

High and low supply voltages are measured only if an external power

supply has been configured to be used over GPIB by the test system and

if the parameter 20. RT Test at Extreme Settings [0=no 1=yes] is set to

1. See “TEST_13 - TXA Current Drain” on page 36 for details on

configuring an GPIB power supply.
