In a gain measurement the following result formats are available:
Gain Result Formats
Gain result format equations
The Gain results are calculated based on the following equations:
Gain H:
where h is the magnitude of gain H and φ the phase of H.
ω is the angular frequency

Magnitude: Displays the magnitude of the measured
Gain.
Magnitude (dB): Displays the magnitude of the
measured Gain in dB
Phase (°): Displays the phase of the measured Gain in
degrees.
Phase (rad): Displays the phase of the measured Gain
in radians.
Tg: Displays the group delay of the measured Gain in
seconds (see
Polar: Displays the measured Gain in a polar chart.
Real: Displays the real part of the measured Gain.
Imaginary: Displays the imaginary part of the
measured Gain.
Nyquist: Displays the measured Gain in a Nyquist
chart.
Q(Tg): Displays the Q-factor derived from group delay.
This value is used for NISM (see
page 116 for details).
