If the values in the dialog box result in an unfavorable combination, a note is shown.
The note indicates:
●
"Undersampling"
if the carrier frequency is too fast.
●
"CF + BW/2 > DevBW"
, where CF is the carrier frequency, BW is the filter band-
width, and DevBW is the maximum instrument bandwidth.

As usual, the signal icons of the enabled channels show the current settings. In I/Q
mode, the I/Q settings are shown, see Figure 17-1. The left signal icon shows a com-
plex input signal in IF range with carrier frequency 1 MHz and normal/upper sideband.
C1 is the in-phase component, C2 the quadrature component. The right signal icon
shows a real input signal with carrier frequency 1 MHz. C1 has inverse sideband, C2
has normal sideband.
