Shifting linear Sim results in frequency

Question asked by SLO_001 on Dec 17, 2003

Example:
RF BPF centered at 400MHz is simulated (for group delay)
Functionally, BPF is connected to a mixer, shifting the output down to say 70MHz.
Group Delay equalizer is then used to flatten the delay response.

Is there a way to bring the GD response of the RF filter down in frequency so that I can include the response of the IF GD equalizer?  Overlay, cascade the responses, etc.

Looked (and still looking) through the help files on Post Processing but haven't had much luck.
