58 N9320A Spectrum Analyzer
3 Functions and Measurements
4 Set the resolution bandwidth to 10 kHz:
Press > Res Bw > 10 > KHz
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 Connect the cable (but not the DUT) from the tracking
generator output to the analyzer input. Store the frequency
response into trace 3 and normalize:
Press > Tracking Generator > More > Normalize > Store Ref (1
3) > Normalize (On)
7 Reconnect the DUT to the analyzer. Note that the units of
the reference level have changed to dB, indicating that this
is now a relative measurement.
8 To change the normalized reference position:
Press > Tracking Generator > More > Normalize > Norm Ref
Posn > 8
9 Place the reference marker at the specified cutoff frequency:
Press
> Delta Pair (Ref) > 370 > MHz
10 Place the second marker at 37 MHz:
Press
> Delta Pair (Delta) > 37 > MHz
