HP 8753E manual Kge, Using Continuous Correction Mode

Note Because power meter calibration requires a longer sweep time, you may want

to reduce the number of points before pressing :~~;-c~~~~~~. After the

power meter calibration is Gnashed, 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.

10. Remove the power sensor from the analyzer test port and connect your test device.

Using Continuous Correction Mode

You can set the analyzer to update the correction table at each sweep (as in a leveling application), using the continuous sample mode. When the analyzer is in this mode, it continuously checks power at every point in each sweep. You must keep the power meter connected as shown in Figure 5-9. This mode is also known as power meter leveling, and the speed is limited by the power meter.

Note You may level at the input of a device under test, using a 2-resistor power splitter or a directional coupler before the device; or level at the output of the device using a 3-resistor power splitter or a bidirectional coupler after the device.
