IF Spectrum Preview

A preview of the measured spectrum (power level vs. frequency) for the IF (intermedi-
ate frequency) signal is provided. The center frequency is the nominal channel fre-
quency. The frequency range shows the measured bandwidth. The power range is
selected such that the noise level remains visible.
