OK, thank you for the detailed reply Andrew. My knowledge of FFT mathematics is very basic so I am wondering if it would be possible to include spectrum analysis using either a variable center point or start point/end point in a future update? Last week we had a demonstration of spectrum analyzers a...

I want to setup my 3206 to do some IMD measurements on a transmitter. All of the FFT screens start at 0 Hz so I can, for example, scan from 0-50 MHz or 0-100 MHz. How do I set the instrument to scan from a non-zero frequency, say 44,9 MHz to 45,1 MHz? I know I can do this using the zoom function but...
