Note:
●
Make sure to select the correct configuration, according to your cabling.
●
If the internal combiner is used, lower- and upper-tone signals use the same path,
and hence only "Lower Tone" can be selected.
See "Receiver Input" on page 678.
Receiving Port
Selects the receiving port for the signal from the output of the DUT.
Remote command:
[SENSe<Ch>:]FREQuency:IMODulation:RECeiver
Sweep and stimulus setup
IMD Sweep Type
The intermodulation distortion measurement can be performed with three different
sweep types. The sweep parameters to the right of the "IMD Sweep Type" selector
change accordingly.
"Lin Freq"
The channel is set to Lin Freq sweep type. The lower tone port
sweeps with channel settings (see "Start Frequency/Stop Frequency/
Number of Points/Freq Step Size/Base Power" on page 387), the
upper tone in parallel with a given Delta Frequency.
"Power"
The channel is set to Power sweep type. The lower tone port sweeps
with channel settings (see "Start Power/Stop Power/Number of
Points/Fixed CW" on page 387), the upper tone in parallel with a
given Delta Frequency.
"Delta F"
The channel performs a CW Mode sweep whose standard parame-
ters can be set in the dialog (see "Start delta Freq./Stop delta Freq./
Number of Points/Base Power/CW Frequency/CW fixed to"
on page 387).
The frequency distance between lower tone and upper tone starts at
"Start Delta Freq." and ends at "Stop Delta Freq." (grows or shrinks
linearly). Either the lower tone or the upper tone remains at the con-
figured CW Frequency ("CW fixed to": "Lower Tone"/"Upper Tone").
As a third possibility, the center between lower tone and upper tone
can remain at the configured CW Frequency ("CW fixed to": "Center".
For the related parameters, see "Start delta Freq./Stop delta Freq./
Number of Points/Base Power/CW Frequency/CW fixed to"
on page 387.
