NOTE
The E4418B and E4419B power meters have a "437 emulation" mode. This
allows these power meters, with an HP/Agilent 848X-series power sensor, to
be used with the network analyzer. In this step, when selecting a power
meter, choose the 438A/437 selection.
6. Set test port power to the approximate desired corrected power.

8. If you want the analyzer to make more than one power measurement at each frequency
data point, press:
NUMBER OF READINGS
If you increase the number of readings, the power meter correction time will
substantially increase.

NOTE
Because power meter calibration requires a longer sweep time, you may want
to reduce the number of points before pressing
power meter calibration is finished, return the number of points to its original
value and the analyzer will automatically interpolate this calibration. Some
accuracy will be lost for the interpolated points.
The analyzer will use the data table for subsequent sweeps to correct the output power
level at each measurement point. Also, the status annunciator PC will appear on the
analyzer display.

You can abort the calibration sweep by pressing
