New Trace (ADC) dialog box help |
|
On the New Trace dialog, click the Receivers tab. Activate - check any empty line to create a trace. Numerator - select from the following:
Denominator - NOT available (ONLY unratioed measurements) Source Port - The ADC receiver is measured when the specified source port is sweeping. Select None to always measure the ADC receiver. |

Analog IN Range |
Analog In Range can be set at Meas > Auxiliary. > AuxInN Range. (E5080A only)
ADC receiver traces are labeled as shown in the following images:
The ADC1 input is being measured, with 2 as the source port.
The Y axis is U (unitless).
The default trace format is Real (linear).
Although most VNA functions work with ADC traces, the following may be especially useful.
Equation Editor can be used with the trace data. Although the VNA ADC is measuring voltage , by using a trace formula, this voltage can represent other types of measurement parameters (such as current, temperature, or a scaled voltage). See PAE example.
Trace averaging and Trace Smoothing can be used to remove trace noise.
Dwell time can be used to allow for settling.
Calibration for ADC receivers is NOT supported.
Not supported in Noise Figure application
