Calibrating for Increased Measurement Accuracy
Power Meter Measurement Calibration
NOTE Remember to subtract the through arm loss from the coupler arm loss before
entering it into the power loss table, to ensure the correct power at the output
of the coupler.
4. Repeat the previous two steps to enter up to 12 frequency segments, depending on the
required accuracy.
You may enter multiple segments in any order because the analyzer automatically sorts
them and lists them on the display in increasing order of frequency.
If you only enter one frequency segment, the analyzer assumes that the single value is
valid over the entire frequency range of the correction.
5. After you have entered all the segments, press .
6. Press to activate the power loss compensation.
Using Sample-and-Sweep Correction Mode You can use the sample-and-sweep mode to correct the analyzer output power and update
the power meter correction data table, during the initial measurement sweep. Because the
analyzer measures the actual power at each frequency point during the initial sweep, the
initial sweep time is significant. However, in this mode of operation the analyzer does not
require the power meter for subsequent sweeps. Therefore, this mode sweeps considerably
faster than the continuous correction mode.
