content: Have had my Rigol 50MHz DS1052E for about a month and have some issues using itIts Sware Version 00.02.04 (And no, ive never tried to upgrade it !)1. Mostly cant get it to trigger to a stable waveform on a "normal" waveform(Eg Last Example: output from a 20MHz xtal oscillator with rounded edges typical of this package.)Correct channel is triggeredNo matter what trigger criiteria set up in trigger menu its the same, just drifts slowly over the screenSwapping channels over and resetting trigger channel, no differenceEnabling both Ch1 and 2 and attempting to trigger from either (probes commoned), wonttrigger (Yes, trigger is set internal)Sometimes, without reason, the trace locks on and its OK. (usually from exiting a menu, any menu)Sometimes it takes 10 to 15 minutes of random menu chnaging to get it to lock.Even LF square waves are the same,Note that the sweep settings are chosen around the time frame of the applied signalAlso that when the signal does lock its very jittery (on higher frequencies)Note that the same signal and probes locks IMMEDIATELY on an analog scope !Eg: BWD model 824 35MHz scope The sigmals are now clean, stable with no jitter.(So there no problem with the signal itself)Is this a common problem with this CRO? Its really usable only about 15% of the time as it is.2 Saving a file : If lower case selected (default) then you can enter ONLY the first letter ofa file name.Every other letter wil be a 'u' no matter what you do or what selection line you are on. BUT change to upper case and theres no problem.! (Yes, English is chosen....though most of the'sign on' stuff in the displayed box is in ChineseIs this a known fault with the Rigol? .3: When probe set to X10, I set the menu to X10 to match. But ive noticed if I change the menuto X1 (or any other "Xx" setting) the diplayed voltages and the waveform amplitude stayexactly as they were. The menu setting of probe attenuation does not seem to affectthe display at all, all displayed input voltages stay unaltered.. That doesnt seem rightSwitching the probe over to X1 increases amplitude by 10 as expected, but voltages displayeddont alterComment on supplied probes: THEY ARE LOUSY ! The hook shrouds coninuously drop of the probesYou have to have the hook grabbed on at a +ve angle or the probe shroud just drops off !Also the grabber (hook) angle is too shallow. It doesnt "hang on" properly even on wireor test pins with diameters less than the hooks accessIve 'binned' them and use my TEK or HP probes They workFinally: When I opened the box on receipt I noticed the plastic probe 'envelope' was empty.The probes were lying in the bottom of the box and not wrapped up or coiled.Was it because the CRO was tested before being shipped out and the tech was in a hurry or was this a faulty return passed on to me?(The Rigol was bought on eBay from OZ supplier (paid $475 plus $35 shipping. If i'de wated a few weeks I could have bought one for just over $400 !!Any thoughts on the above? Should I send it back under warranty?Or is it something i'me doing wrongApart from the above I like the machineJohn

(waveform display shouldn't change unless you physically adjust the probe attenuation though)

content: It doesn't look like the OP has been active in 6 years (last post was August 2010), so I wouldn't expect an answer from him. I seem to remember reading about some trigger issues with DS1052E, though could be wrong. I would continue searching on these forums. The search button directly above where the posts start seems to do a better job of finding what you are searching for than the search box at the top of the page.
