Sorry for being very late to the party, I just saw this thread (been buried in work for months, never had time for a proper review).
I have bought the RTC1002 in the all-upgraded RTC1K-COM2 package for about $1500 USD, back in august.
I never had the time for a proper review, here are some notes...
I am absolutely completely and utterly satisfied.
Unit boots in 7 seconds. UI is very responsive and all-around excellent.
I have owned both Rigol and Siglent scopes. They were very fine units for their prices, but they still have a long way to go to catch R&S or Agilent on UI.
Unit is incredibly compact and silent. I transport mine in a camera bag made for a DSLR.
Analog probes are cheapies. Digital probe is nice.
Protocol decoders work very well. No complaints.
20 divisions scrollable vertical "virtual" screen is quite useful.
SQUARE divisions. (Important to me). Also on the siglent.
The screen is a 4:3 ratio 6.5 inch LCD, but will show you 12 horizontal divisions, so it has a bit of horizontal expansion compared to a classic 10x8.
Most widescreen scope simply use rectangular divisions, though I believe my Rigol DS2072A could show 14 with menus off.
Keysight just wastes the horizontal space with a big logo and some setup info they could put on the bottom.
This is not my only scope, I also own a Tek TDS784A with 4 active probes, so I use that when I need 4 analog channels, very high bandwidth or excellent probes.
RTC1002 has displaced my beloved analog scope (Tek 2465) from the bench though. Since sold at a 50% profit. I'll get over it some day.
-3dB bandwidth is precisely 300MHz (measured with a good Keysight sig gen).
Trigger bandwidth (and frequency counter limit) is 454 MHz on my unit.
Look for Dave's video #842 of the HMO1202. This is the same scope, minus the switchable 50 ohm input (a shame!).
I use the FFT a lot. It's the best user interface implementation I have ever seen on a scope. Just a blast to use. (EEVblog 845 to see it in action)
So does the base model make sense compared to the rigol and siglent? Probably not, as it's twice as expensive.
Does the discounted high-end model make sense? Certainly, it's half the price of a comparable keysight (MSOX2022A, only 200MHz bandwidth and half the memory).
It's also price-competitive with the Rigol MSO2302A-S and the Siglent SDS2302XE with mso option.
