The tuning voltages (alternatively: current) applied during the measurement depends
on the tuning range you have defined.
The y-axis shows the output power of the VCO at a given tuning voltage or current in
Hz.
Remote command:
TRACe<n>[:DATA]? on page 333
Current / Voltage
The "Current / Voltage" result display shows the voltage or current that the DUT is sup-
plied with by the selected fix source and displays the result for each measurement
point. Each measurement point corresponds to a specific tuning voltage (or current)
that was applied to the DUT.
The x-axis shows the tuning characteristics of the DC source.
●
For V
supply
the tuning voltage in Volt or current in Ampere, depending on the output
type.
●
For V
tune
and V
aux
the tuning voltage in Volt.
The tuning voltages (alternatively: current) applied during the measurement depends
on the tuning range you have defined.
The y-axis shows the current or voltage of the selected fix DC source. When V
Supply
is
configured to supply current and selected as the "Fix Source", the diagram shows the
voltage in Volt. In all other cases, it shows the current in mA.
Remote command:
TRACe<n>[:DATA]? on page 333
Power vs. Frequency
The "Power vs. Frequency" result display shows the frequency characteristics of the
DUT as a function of the tuning voltage or current.
The x-axis shows the frequency on which the VCO operates at a given tuning voltage
or current in Hz.
The y-axis shows the output power of the VCO at a given tuning voltage or current in
Hz.
Remote command:
TRACe<n>[:DATA]? on page 333
Harmonic Power
The "Harmonic Power" result display explicitly shows the power of the fundamental
wave and the power of the harmonics of a DUT measured for each measurement
point.
The x-axis shows the tuning characteristics of the DC source.
●
For V
supply
the tuning voltage in Volt or current in Ampere, depending on the output
type.
●
For V
tune
and V
aux
the tuning voltage in Volt.
The tuning voltages (alternatively: current) applied during the measurement depends
on the tuning range you have defined.
The y-axis shows the output power of the DUT at a given tuning voltage or current in
dBm.
