Using Continuous Correction Mode; Continuous Correction Mode For Power Meter Calibration - Agilent Technologies 8719D User Manual

Because power meter calibration requires a longer sweep time, you may want
to reduce the number of points before pressing .XME ML~-?MEE.. After the
power meter calibration is finished, return the number of points to its original
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.
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.
You may level at the input of a device under test, using a Z-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.
Figure 5-9. Continuous Correction Mode for Power Meter Calibration
1. Connect a power splitter or directional coupler to the port supplying RF power to your test
device, as shown in Figure 5-9.
2. Set test port power to approximate desired leveled power.
