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
