I have a downconversion mixer (fc = 2.1 GHz, BW=800 Mhz, i.e. f = 1.7 ... 2.5 GHz). For the reference side band I set -1.

The absolute start/stop frequency in pnoise, would I set it to 1k ... 400M or to 1.7 G ... 2.5G?

I found documents (e.g. **broken link removed**) where they say the former (1k....400M). Older saved states of my own have that set too.

But now I'm confused. Shouldn't it be the latter, i.e., the exciting frequencies (and hence 1.7GHz ... 2.5GHz)?

I don't know what simulator you use.

However if you use Pnoise Analysis in Cadence Spectre, it has to be 1kHz-400MHz.

You can confirm which setting is reasonable, if you surely see simulation logfile.
