Resolving fast edges.

FWIW all 100x HV probes we sell are 300 MHz rated not because we need such but that's what the manufacturer offers. Here like most, maybe all of EU mains is 230VAC and 3ph 415VAC between phases and being low impedance IMO it's wise to protect the instrument and yourself with a HV rated probe with better breakdown specs rather than any 600V rated probe.

I’m starting to think, for my SDR work and working with IF and FOGAs, maybe I should stretch my budget up to an MSO5000 series. 😅 Probably save me on a nicer signal generator and logic analyser etc. TEquipment sell a 5074 with logic probe. But it’s looking expensive, even from TEquipment, about AU$2000 landed.

A couple things to think about that might save you some money on the logic probe:

  - there are people selling a non-Rigol version of the logic probe (based on designs that were developed in discussion threads on EEVBlog).  On US eBay they run about $80 USD shipped to the USA.  I'm not sure how the quality compares or what feature differences there might be (like supported signal voltages) different from the Rigol logic probe.

  - unless you need to have your logic waveforms displayed with and synchronized with analog signals, one of the many inexpensive USB logic analyzers might save you a fair bit

It isn't a 300MHz HV probe--it can be used as a 300MHz probe or a HV probe, but not both at the same time.  It's main feature will be a lower input capacitance, the 100M input resistance is mostly a sideshow.

Don't ever imagine an inbuilt AWG will meet your every need.
Typically their drive levels (p-p) are lacking for a multitude of uses.....just so you know.  ;)
