Making Mixer Measurements
Conversion Loss Using the Frequency Offset Mode
Performing a Power Meter (Source) Calibration Over the RF Range
1. Calibrate and zero the power meter.
2. Set the power meter's address:
(where aa is the GPIB address of the power meter)
3. Select the appropriate power meter by pressing until the correct model number is
displayed (Agilent 436A or Agilent 438A/437).
NOTE The Agilent E4418B and E4419B (EPM) power meters have a “437emulation” mode which
can be used in this procedure by following these steps.
• If you are using an Agilent EPM power sensor and your network analyzer has firmware
revision 7.72 or greater:
a. Select the remote interface command set on the power meter by pressing the System
Inputs key and the following softkeys: Remote Interface, Command Set, SCPI
b. Skip step 4 and continue at step 5.
The power sensor factors are automatically read by the analyzer.
• If you are using an Agilent 848X-series power sensor or your network analyzer does not
have firmware revision 7.72 or greater:
a. Choose the 438A/437 selection on the network analyzer by pressing:
until it reads
b. Select the remote interface command set on the power meter by pressing the System
Inputs key and the following softkeys: Remote Interface, Command Set, 437B
4. Press and enter
the correction factors as listed on the power sensor. Press (where fff is
the frequency of the calibration factor in MHz) (where nnn is the
calibration factor number) for each correction factor. When finished, press .
