Frequency Response Preamp On Adjustment

(N9912A)

All adjustments will require the CFG Option. Refer to the CFG Option section for more information.

This adjustment determines gain compensation factors for multiple frequencies in each SA band (up to 40 per band). Preamp is on. Internal temperature is also stored as part of the adjustment result.

When this adjustment is performed, the current internal temperature of the UUT is stored as part of the adjustment result. The reading from temperature sensor RF2 is stored for each of the eleven bands.
