4800 MHz Calibrator Amplitude Adjustment

This adjustment applies to the following models with Option MPB and frequency options above 503:

EXA — N9010A/B/N
MXA — N9020A/B, N9021B
PXA — N9030A/B
UXA — N9040B
NFA — N8973B/74B/75B/76B

This adjustment sets the 4800 MHz calibrator amplitude to –28.00 dBm in Preselector Bypass path. The adjustment is performed by inputting a 4800 MHz, –28 dBm signal into the analyzer. 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.
