Procedure
1. If you use the Keysight 4195A:
Set CONFIG to SPECTRUM.
Set SOURCE CH1 on.
Set CENTER to 50 MHz, SPAN to O Hz.
Connect the adapter, feedthrough and probe adapter to the S1
connector.
If you use the Network Analyzer:
Select the absolute power amplitude measurement mode (R, A, or B).
Set CENTER to 50 MHz, SPAN to O Hz.
Connect the adapter, feedthrough and probe adapter to the source
output connector.
If you use the Spectrum Analyzer:
Set CENTER to the calibration output frequency.
Set SPAN to O Hz.
Connect the feedthrough and probe adapter to the calibration output
connector.
2. Connect the 41800A's OUTPUT connector to the instrument's INPUT
connector.Insert the 41800A's probe tip into the probe adapter.
3. Note the measured value, and remember it as data
R
. Data
R
is used in
steps 7 and 9.
Data
R
= __________ dBm
4. Disconnect the 41800A from the probe adapter.
If the spectrum analyzer has the tracking generator output, use the
tracking generator output connector instead of the calibration output
connector.
