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

8. If you want the analyzer to make more than one power measurement at each frequency
data point, press:

If you increase the number of readings, the power meter correction time will
substantially increase.

Because power meter calibration requires a longer sweep time, you may want
NOTE
to reduce the number of points before pressing
the 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.
