Calibration for NA, CAT, and VVM Modes
— Select User Waveguide. Then press Done.
—Then DTF Cable Specifications
, then Edit/Save/Recall Cables, then
Edit Cable
.
—Scroll to set Waveguide Definition. The default setting is VF Corr =
Auto.
— Set the Min, Max, and Cutoff Frequencies.
—Press Done
, then press Back.
— Cable Correction = Auto is the default setting. The Effective Velocity Factor
is calculated automatically based on the frequencies of the waveguide
standard. To override this setting, set Cable Corr = Man.
NA Mode - How to make Waveguide settings
These settings are necessary ONLY when your measurement requires electrical
delay or port extensions, or if using Time Domain Transform.
—Press Meas Setup 4
—Then Transform
—Then Transform Settings
—Under Transform Stimulus Settings, set the Start and Stop frequencies to
those of the Waveguide.
—Set Stimulus = Bandpass Impulse
—Press Done
—Press Meas Setup 4 or Back
—Then Calibration Settings
—Set Media = Waveguide
—Set Cutoff Frequency. This is the absolute minimum frequency of the
waveguide. This value must be less than the Start Frequency of the
Waveguide.
Enter the calculated Effective VF value into the Velocity Factor setting.
Enhanced Response Optimization
When Enhanced Response Cal Type is selected, either for one calibration or for
CalReady, this setting optimizes the calibration based on the type of DUT
being measured. See also: CalReady Properties in “CalReady” on page 89.
This setting does NOT survive Preset.
