Keysight Technologies N9330B User Manual page 25

Example: setting a frequency range from 1
1 Press {Start} > [1000] > [ENTER] to set the start
frequency to 1 GHz
2 Press {Stop} > [2000] > [ENTER] to set the stop
frequency to 2 GHz
The start frequency of 1000.0 (in MHz) displays at the
left lower corner of screen, and the stop frequency
2000.0 displays at the right lower corner of the screen.
Step 3. Calibrating the N9330B
The N9330B must be calibrated before making an actual
measurement (SWR/Return loss/Cable loss/DTF) using
the selected frequency span or the full span of the
instrument. The N9330B offers two calibration modes:
• FullSpan Cal
Performs an Open-Short-Load calibration across the
full frequency range. The tester allows you to modify
the frequency range for measurement after the
FullSpan Cal is performed.
• SelectedSpan Cal
SelectedSpan calibration is the default calibration
mode. Performs an Open-Short-Load calibration
across a user-defined frequency range. The tester
requires re-calibration if the Selected Frequency Span
is changed.
Key access: [SYS] > {Cal Mode}
Example: Performing a calibration
Assuming the Selected Frequency Span is from 1 to 2
GHz for return loss measurement and the T-combo
calibrator tool is being used.
1 Press [CAL] to bring up a dialog box that will guide
you through the calibration. The normal calibration
order is open, short, and load.
2 Fasten the OPEN end of the T-combo to the RF OUT
connector on the top panel of the tester, then press
[ENTER] to initiate the open calibration.
