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]

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]

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]

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.

Phase noise and baseband noise measurements:

●

"Noise Diagram"

●

"Integrated Measurements"

●

"Spurious List"

●

●

" Marker Table "

●

"Allan Variance / Allan Deviation"

(Phase noise measurement only.)

VCO characterization measurements:
