For the other two outputs (V
tune
and V
aux
), the maximum current that can be drawn by
the DUT is fixed to the value supported by the hardware. The "Max Curr / Volt" infor-
mation is read-only information for these two outputs.

Reading the actual output levels ← Configuring the DC power output
The actual output levels (voltage and current) for each output source is displayed in the
"Results" part of the dialog box.
When the output levels are as you have defined them, the font of these result values is
green. If the voltage or current that is output differs from the values that you have
defined, the font turns red.
This may be the case , for example. If the DUT draws too much current, and the volt-
age required for that current would exceed the limits you have defined.

VCO Characterization Configuration
Access
(measurement): "Overview" > "Select Measurement" > "VCO Characteriza-
tion"
The VCO characterization measurement determines the characteristics of a DUT when
you apply different input voltages or current (the tuning range or sweep range). The
DUT can be, for example, a voltage controlled oscillator (VCO) or a YIG oscillator
whose characteristic are a function of the applied current. The measurement provides
results for characteristics like the oscillation frequency at a certain input voltage, the
output power or the sensitivity of the DUT.
VCO measurements basically provide the following measurements types.
●
Normal VCO measurements
In a typical VCO measurement, the "Sweep Source" is connected to the tune port
of the DUT. The "Fix Source" is connected to the supply port of the DUT.
