62 N9320A Spectrum Analyzer

3 Functions and Measurements

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.
