VCO characterization
Provides tools to measure various characteristics of DUTs whose characteristics
change depending on the applied voltage or current. Examples would be voltage con-
trolled oscillators (VCOs) or YIG oscillators.
The measurement is designed to evaluate DUT characteristics as a function of the tun-
ing voltage (also known as sweep voltage).
Remote command:
CONFigure:VCO:MEASurement[:STATe] on page 324
Spot noise vs tune
Provides tools to measure the spot noise characteristic of DUTs whose spot noise
characteristic changes depending on the applied voltage or current. Examples would
be voltage controlled oscillators (VCOs) or YIG oscillators.
The measurement is designed to evaluate DUT spot noise characteristic as a function
of the tuning voltage (also known as sweep voltage).
Remote command:
CONFigure:SNTune:MEASurement[:STATe] on page 324
PN Transient analysis
Provides tools to analyze the transient response of a DUT.
The measurement is designed to monitor the frequency and phase variations of a sig-
nal over time and to find out how long it takes until the signal is in a stable state.
Remote command:
CONFigure:TRANsient:MEASurement[:STATe] on page 324
5.4 Result Displays
Result displays show different aspects of the measurement results in numerical or
graphical form.
Depending on the measurement, one or more result displays are supported.
