Paul... does R&S offer similarly discounted MXO4s with lower specs (say 1GHz instead of 1.5GHz)?

I've been comparing the SDS3104X HD and the 4104HD.  Screen on the Lecroy is slightly larger, sample rate a bit higher.  I see an optional spectrum analyzer upgrade for the Lecroy.  Much larger memory on the Siglent.  Apparently no web control interface on the Lecroy (just something called MAUI).  2x price difference.

I do some work with frequency synthesizers (think TI LMX or similar) and would like to look at the frequency settling time when the part is reconfigured.  I saw Shahriar do something like this in his Signal Path review of the Tek MSO6 series.  On the SDS3000X can I do a long capture and then look at the spectrum of a short portion as I sweep along the captured waveform?

Calling @2N3055 to answer this in detail.

I don't think we have anything like that at this time, but I'll check with our North American oscilloscope product manager - I'm not personally involved with deciding what we include in bundles / promotions.

Yes, using the Analysis Gate function you can pick an arbitrary max. 4 Mpts long portion of the record for FFT analysis.
