RF Level, Frequency and IF Spectrum Display

The measured RF power and frequency of the LF input signal is displayed both numer-
ically and graphically.
Figure 4-26: RF level display
The following results are provided:
●
Numeric power level in dBμV or dBm ("Lev")
●
Measured frequency offset to the tuned carrier frequency in kHz
●
Bargraph indicating the power (blue) and a color-coded overload state, where:
–
–
–
●
If applicable: "ADC Overload" message
The dynamic range of the A/D-converter is exceeded (clipping).
IF Spectrum
A preview of the measured spectrum (power level vs. frequency) for the IF (intermedi-
ate frequency) signal is provided. The center frequency corresponds to the tuned car-
rier frequency. The frequency range shows the measured bandwidth. The amplitude
range displays the entire dynamic range.
