4800 MHz Calibrator Amplitude Adjustment

This adjustment applies to the following models:

N9048B PXE with frequency options above 503

This adjustment sets the 4800 MHz calibrator amplitude to –28.00 dBm. The adjustment is performed by inputting a 4800 MHz, –28 dBm signal into the DUT. A reference measurement is made on the input signal. Next, the internal 4800 MHz calibrator is switched into the path and the amplitude is measured. An internal DAC is adjusted until the amplitude error is zero.
