How to select a NA Format
— Press Measure 1.
— Then
— Then choose from the following:
Keysight N9912-90001 User's Guide
Format [current setting].
— Log Magnitude Displays magnitude in dB
— Linear Displays positive values only. Y-axis: Unitless (U) for ratioed
measurements; Watts (W) for unratioed measurements.
— VSWR Used mainly for S11 and S22. Displays unitless reflection data.
— Phase Displays phase in degrees. The trace 'wraps' every 360
degrees, from +180 to –180, for easy scaling.
— Smith Used mainly for S11 and S22, which are plotted on a Smith
Chart. Displays series resistance and reactance.
— More then...
— Polar (S11 Only). Displays magnitude and phase of the reflection
coefficient.
— Group Delay Used mainly (S11) only. Displays propagation time (in
seconds) from the RF port to the point where it is reflected, and back
to the A receiver. The aperture setting is the frequency
range/(number of points – 1). Use Smoothing as the Group Delay
aperture.
