IF Input Gain Option EXM

This adjustment applies to the following models:

This adjustment inputs a calibrated –25 dBm signal into the External IF INPUT port. Then the Amplitude Error is measured at the center frequency and at offset frequencies across the IF Bandwidth. The offset frequencies are nominally spaced in 4 MHz intervals. If Option B40, B85, or B1X is installed, the adjustment is repeated for those paths.
