Reset Freq Conv Intermod
Disables the intermodulation measurement mode for the active channel and switches
back to normal mode (no frequency conversion). The intermodulation settings are
maintained, however, the intermodulation traces are eliminated, and the default trace
(S
21
) is displayed.
Remote command:
[SENSe<Ch>:]FREQuency:IMODulation:CONVersion
CW Mode Spectrum
In CW spectrum mode, the intermodulation measurement is performed at fixed fre-
quency of the lower tone ("CW Frequency") and the upper tone ("CW Frequency" +
"Tone Distance"). The analyzer displays intermodulation products up to a selectable
order ("IM Order") around the lower and upper tone frequencies. The channel settings
differ from the swept intermodulation measurement, therefore a new channel is created
when the spectrum measurement is activated ("Add CW Mode").
The following example shows an intermodulation spectrum with the following settings:
●
CW Frequency: 2 GHz (lower tone, position of marker M1)
●
Tone Distance: 3 MHz (defines the upper tone, position of marker M2)
●
Max. IM Order: 9.
From left to right, the peaks correspond to the following intermodulation products:
–
lower IM9
–
lower IM7
–
lower IM5 (marker M6)
–
lower IM3 (marker M5)
–
lower tone (marker M1)
–
upper tone (marker M2)
–
upper IM3 (marker M3)
–
upper IM5 (marker M4)
–
upper IM7
–
upper IM9
