Making a Reflection Calibration Measurement
64
2 Connect the tracking generator output of the analyzer to the
directional bridge or coupler.
3 Connect the analyzer RF input to the coupled port of the
directional bridge or coupler.
4 Press > Preset. (With Preset Type of Factory)
5 Turn on the tracking generator and, if necessary, set the
output power to - 10 dBm
:
Press > Tracking Generator > Amplitude TG (On) > -10 > dBm
6 Set the start and stop frequencies and resolution bandwidth:
Press > Start Freq > 100 > MHz
Press > Stop Freq > 1 > GHz
Press > Res Bw > 3 > MHz
7 Replace the DUT with a short circuit.
NOTE
For greatest accuracy, use a coupler or bridge with the correct test
port connector. Any additional adapters or components placed
between the test port and DUT degrades coupler/bridge directivity
and system source match.
For best results, use the same adapter for the calibration and the
measurement. Be sure to terminate the second port of a two port
device.

CAUTION
Excessive signal input may damage the DUT. Do not exceed the
maximum power that the device under test can tolerate.
