Synthesizer Output Level Adjustment

(M9393A)

The goal of this adjustment is to characterize and track the measured error of output attenuator and output amp settings vs. frequency over a number of target power levels. This adjustment will also perform an RF output power level verification which will verify that the M9308A synthesizer has met the required power output limits in order to proceed with the M9365A downconverter adjustments.

  1. Refer to the main required equipment list for alternative models.
  2. N1914A power meters with serial number prior to MY53040007 require Service Note N1914A-07 which fixes a power supply ground loop. The ground loop injects noise into the measurement circuits which can cause unstable measurements at low (-30 dBm) power levels.
