IF Input Gain Option EXM Adjustment

This adjustment applies to the following models with Option EXM:

EXA — N9010A/B/N
MXA — N9020A/B
MXA — N9021B
PXA — N9030A/B
UXA — N9040B

This adjustment generates corrections for the External IF Input Gain. The basic algorithm inputs a –25 dBm signal into the External IF Input. The DUT is placed in external mixing mode, the corrections are turned off, and the signal amplitude is measured. The amplitude error is stored as a correction. The amplitude error is measured at various frequency offsets (from center frequency) across the IF Bandwidth. This adjustment is performed on the following IF Paths:

IF Path	Bandwidth	IF Frequency
Standard	10 MHz	322.5 MHz
Option B25	25 MHz	322.5 MHz
Option B40	40 MHz	250.0 MHz
Option B85	85 MHz	300.0 MHz
Option B1A	125 MHz	300.0 MHz
Option B1X	140 MHz	300.0 MHz
Option B2X	255 MHz	750.0 MHz
Option B5X	510 MHz	877.1484375 MHz
