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. The peaks correspond to the intermodulation products lower
IM9, lower IM7, lower IM5 (marker M6), lower IM3 (marker M5), lower tone, upper
tone, upper IM3 (marker M3), upper IM5 (marker M4), upper IM7, upper IM9.
Add CW Mode
Activates a new channel for the spectrum measurement. The "CW Frequency" plus
half the "Tone Distance" defines the center of the diagram; the "Max IM Order" defines
its width; see example above.
