I recently had the same dilemma
350 MHz, mixed signed with serial deocders + any extra we can get (R&S spectrograph quite nice)
Mainly keysight kit in the place, so many people used to Keysight '3000 scopes.
RTM2034 -
Good points
3% cheaper
Analog -
2 probes = 5GS/s - 20 Megasamples per channel (vs Keysight 4M total memory )
4 probes = 2.5GS/s - 10Megasamples per channel
Mixed signal
1 probe (8 bits) = 5GS/s - 20 Megasamples per channel (vs Keysight 4M total memory )
2 probes(16 bits)= 2.5GS/s - 10Megasamples per channel
Segmented - 460MSample buffer
45,000+ segments @ 10k samples per segment to 23 segments @ 20Msample per segment - each segment much larger than keysight total memory.
Finer control over sgemented memory (keysight tries to do a good 'auto', but when it gets it wrong there not much you can do)
5us between segments in Ultra mode (= 200,000 waveforms per second)
A then B trigger
Nice 'scope probes
Bigger display (better resolution), for same size 'scope.
Interface fine, Undo / Redo buttons handy.
Clock error.
Good - 2.5ppm (much better than MSO3000A - 25ppm, similar MSO3000X - 1.5ppm)
Weak Points
Much lower waveforms per second (but very low latency between segments is very good for solving some problems requiring high wfps)
Web interface was a little slow (BUT I was running on a very flakey network connection, so I'm not sure it was the scope)
A different set of minor interface quirks compared to Keysight.
In summary....
Pleased with the purchase, great 'scope.
The extra memory is a big advantage over Keysight, BUT some problems need the very high waveforms/s that keysight provides, so it depends what you needed it for.
