3 Press the
{Stop}
softkey to call up the stop frequency
menu. Press
{400} > [ENTER]
to set the stop frequency
to 400 MHz.
4 Press the
[CAL]
hardkey to call up the calibration
process menu. Follow the instructions for performing
the calibration. For more information about
calibration, refer to "Calibrate the N9330B before
making measurements" on page 25 . 
A “Calibrated” indicator will be displayed on the upper
left corner of the screen when the calibration is
completed.
5 Remove the calibrator and connect the DUT to the RF
OUT connector of the tester. The tester will then
measure the return loss of the DUT.
Adjusting the measurement resolution
The tester has three resolution settings, 521, 261, or 131
points. Press the
[MEAS/VIEW]
hardkey, then the
{Resolution}
softkey to choose the resolution setting
desired, then press the
[ENTER]
hardkey to enter the
selection.
The higher the resolution, the more accurate the
measurement results. However, a higher resolution
setting will require a longer sweep time.
Using Marker/Limit
For further trace analysis, refer to:
"Using markers" on page 40 .
"Using Pass/Fail Limit Lines" on page 41
"Trace Operation" on page 43
.
For performing an isolated return loss measurement,
refer to:
"Using single sweep" on page 51 .
For minimizing the interference, refer to:
"Enabling interference immunity" on page 51 .
