displayed (436A or 438A/437).
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.

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