My Fluke Scopemeter 190 has been an invaluable tool since i purchased it used about 5 years ago. I've used it on all of my digital electronics projects many of which involved my little Taig desktop CNC machine. But all good things must come to an end and although it still functions, my little scopemeter is just not as capable as i need it to be in this modern age. I've been looking at the Rigol 1052 as a replacement.

It has 2 analog channels + 16 logic channels which is great for monitoring serial signals and anything with a clock signal. I used a very nice 4 channel Agilent at my last job but i have a bit of sticker shock for that brand. Can anyone vouch for the Rigol brand or suggest another brand/model? Some of the things that set a professional scope like Tektronix apart from the hobbyist type scopes are: - The variety of triggering modes. That's the one that does it. Want to trigger if one pulse in a continuous pulse train is shorter than the others? Or longer than 'X' time?

The Tek digital scopes, especially the 730 I mentioned, will do that sort of thing. There are 6 'screens' of trigger modes on the THS730, I don't recall what they all are even though I have used a lot of them from time to time. Want to know the actual DC level?

The RMS value of the waveform? You can get it. Try that stuff on your 'chinese special'. Which will NOT have isolated inputs, so everything is ground referenced. That's the one that does it.

JT, do you know of a good (i.e. Inexpensive) place to get the replacement 'Stick' battery those Teks use? Mine is shot and I'm tempted to build one up from tabbed Nicads.

Thanks for all this information. I'm narrowing it down to the Rigol 1052D and the Owon SDS7102 or MSO7102. Although i wish i could afford a Tektronix or Agilent, it's just not in the budget. I'm also moving away from a handheld unit. The fluke scopemeter was purchased because it was a great deal that just happened to be portable. The Owon MSO has the logic analyzer but not great memory depth and the SDS series has great memory depth but no logic analyzer and the Rigol seems to be in the middle.

It has 1Mpoint memory depth and a 16 channel logic analyzer. The prices are all fair so it will come down to features. I'm leaning towards the Rigol but I'll see how i feel in a few days after i have a good think about it. Also, I didn't see an Owon distributor in the U.S. There are 6 'screens' of trigger modes on the THS730, I don't recall what they all are even though I have used a lot of them from time to time.

A quick read of any of the manuals for the 'chinese specials' will show that they have the capabilities you mention. The few Rigol (and Atten (I found all have advanced triggering and measurement facilities. I bought a (Taiwan) GW Instek 840 (a couple of years ago (to replace an aging Tek TDS410a).

Thanks Walt I modified my THS710A to take everyday AA / C rechargeables: (While the automatic measurements, advanced triggering etc.

Are not uncommon these days, the ability to operate with the probe common at up to 600V rms relative to ground is a killer feature. (.Possibly literally:eek:) Cheers.

If you limit yourself exclusively to scopes which include logic analyzers, dome lights, and ashtrays, you will absolutely EXCLUDE all the best oscilloscopes. But of course it is your choice to do that. Kto hochet statj millionerom delphi. There are available logic analyzers, and oscilloscopes, and most will be better if separated than if combined. Logic analyzers in particular are available as all sorts of devices starting with inexpensive devices working with PCs, etc.

There is no particular reason to demand that it be crammed into the 'scope, unless you fly to your repair jobs and absolutely MUST carry only one single solitary piece of test equipment. When using any kind of measurement equipment, 'trusting' the measured result is key. High quality probes can cost as much as the chinese scopes, but you will be able to trust what you see on the screen. This is more so when the frequency you are working with goes up. Use a cheap probe, and it will distort, attenuate or otherwise modify the signal being measured. If I already have enough bugs with the circuit I'm working on, the last thing I want to do is question whether the scope is telling me the truth or not.
