Yep, and the price difference with the competition was much larger.

FWIW: It looks like Rigol is about to create a new "benchmark" with their DHO800 series but we're only at "preorder" status right now.

I'll go further and say there's no perfect 'scope at any level.  :)

But yeah, don't expect any of these 'scopes to be 100% amazing and have no problems.

(Think: If they were then there'd be no $1000 or $2000 'scopes on the market.  :popcorn: )

FYI
SDS1104X-E is supplied with PP510 100 MHz rated probes whereas 200 MHz SDS1204X-E is supplied with PP215 probes.
Their frequency responses were checked by member Performa01 and PP510 was down 1dB at 200 MHz compared to PP215.

These results indicate PP510 will give satisfactory accuracy for most work at frequencies well above their rating.

* fair quality for the price,
* regular models are all easily hackable (MSO doesn't, but it's another story),
* fairly wide range of trigger options (for example RUNT),
* meet the specs, even near the extremes,
* lightweight and compact.

How about:

It has a row of buttons down the left side for turning on measurements very quickly/easy (something which you do a lot...)

Siglent's system for turning on measurements is a real pain in the ass by comparison.

QFT.

corey:
Thanks all! I'm quite surprised at the level of responses - some long and detailed. I acknowledge I didn't mention the intended use, and hence it's somewhat of a difficult question to answer! ;D But thanks to all, this is quite the helpful community.

I'm leaning toward the Siglend SDS1104X-E, which is available at AppVision for $693 incl GST currently. https://appvision.com.au/index.php?id_product=119&id_product_attribute=0&rewrite=siglent-sds1202x-e-digital-oscilloscope-200mhz-2-channel-1gss-with-serial-decode&controller=product

Second in line is a GWInstek. Sounds like it is stronger in the decoding from memory, which I'm also likely to need.

Intended use is SDR (low RF up to 1GHz, IF), ADC/DACs, as well as digital interfaces (to an FPGA). RF/IF is why I was going for highest bandwidth possible. I'm thinking I'll get a separate logic analyser (e.g. Saleae? Haven't looked at pricing) but would be great to go for a MSO, I just don't think I have the budget. So I'm also interested in the FFT capability, which sounds like is good on the 1104X-E.

Must say, though, we're spoilt for choice. When I was at university 15-20 years ago, CRO/DSO's were $$$.

Professzore:
Well,

Yes, sure. On the other hand, you can be easily messed up when you fill up all the free places, and you're going to change one less used to a new one. I use cursors in about 95% of all measurements.
