Thanks Justin.
Another question (sorry!). Over on another site, were were comparing TG crosstalk levels on another well-known analyser (Rigol). Once we’d done that, I thought I’d see what result the SH returned (should be very low level). I set up a sweep from DC to 1.5 GHz and noted the baseline noise level, but just by chance I then raised the start freq to 300 KHz and the niose level dropped by several dB. Is this anything to do with the auto-settings reducing the DC spike? Or is something odd going on?
