Well I took a chance and bought this meter. And when I got it, it had version R11 firmware. I was doing some testing of the unit and it seemed just about the same as the Signal Path review, though I think he was using R12. I wasn't exactly impressed. All of my fears on this meter were there. The slow everything was just a little sub-par. Still for the money, it's not too bad, but there were enough issues that I wasn't smiling. So I downloaded the R13 firmware from Siglent (without much hope based on previous comments from Armxnian) and installed it. Wow, a real step up in speed on a lot of functions. The continuity was usable (R11 had a poor response time). For R13, if the connection is really brief, it may miss the event, but generally it's pretty fast. I would say just marginally worse than my old Fluke 87 III, which I've never had a complaint about. And if you up the threshold limit, it does get faster. Still at 50 Ohm, it's pretty good. The ranging is much faster. R11 was doggy switching from 2V to 20V range in DCV (middle speed), now it's as fast as I can move from a 1V to 10V output on the DP832! Not too shabby. Even the .1V (200mV range ) to 30V (200V range) switch is quick. Again, from my last post, using the slow speed isn't fair for range switching since the integration time is already 1s, so you can't expect the display to switch sub 1s when the periodic update speed is 1s.
The meter's performance is pretty good. Measured up to 3MHz on frequency, even though the signal was severely attenuated...in the 100s of uV. DCI/Ohms agrees with my Fluke (to it's 3.5 resolution). I have the .1% IET decade resistor box at work, I'll borrow it and test it out.
Again, overall, I'm pretty happy with the R13 update. Still room for improvement, but if the incremental updates are any indication, at least it's going in the right direction. Still wish there was an ultra fast speed.
Sadly I bought a Keithley 2110 reasonably cheap on Ebay, now I have to decide which one stays and which one goes.
