DS1052E issues - can not adjust the (V/div) or (time/div)

[ant452]

Hi All,

I have a Rigol DS1052E its 12 months old and has had only light use.
Last time I used it I was plying around with the triggering now however it seems its somewhat stuck in the trigger menu as the inputs do not seem to function correctly.    Power off/on does not help.

I turn it on and press AUTO with channel 1 connected to the test signal, it captures the test signal fine.
But when I turn the vertical scale knob (V/div) nothing happens, turning the horizontal scale knob (time/div) it moves the trigger point ie to left or right of center, but not (time/div)

I can not adjust the (V/div) or (time/div). 

Am I stuck in the trigger menu? Is there setting/menu option I need to exit out of?
Any ideas how to fix this, I'm hopeing its a case of user error and that's its not busted 

I have tried self Calibrate and also Storage - Factory - Load.

Press the CH1 button then use the knobs? IIRC the knobs just operate whatever you last pressed.

Are you using the right knobs? The smaller one moves the waveform timebase and voltage offset. The larger knobs should change the time/volt divisions.

Otherwise it sounds like its gone a bit nuts... Perhaps firmware update?

Is this a hacked scope?

Thanks for the advise

Yeah, though there was slight error in my initial description,  the horizontal scale knob (time/div) moves the trigger level

Is this a hacked scope?

It initially occured on firmware 2.06 given that Self Calibrate and also Storage - Factory - Load did not help I tried updating the firmware, so I loaded Gizmo's ver 4 firmware, but no luck I still have the same problems.

Any further ideas/suggestions? Would really like to get this scope working again

Once hacked or firmware changed all bets are off in terms of troubleshooting; whatever advise we can give is based on factory default setup.  Since the knobs are stuck, its doesn't sound like a hardware fault, i.e. rotary encoders, it sounds like a firmware fault.

[ant452]

After having a further play with this (tried down grade firmware etc.) still having the issue.
I have needed to use this lately and its becoming frustrating, can only be used by pressing auto to see a signal, V/div & time/div knobs still not working.

I think this occurred when I was in the UTILITY -> System Info screen and instead of pressing Run/Stop to exit I pressed other buttons ie tried going to trigger menu etc.  I think I entered some key combination to put it in an odd state/mode

Any ideas on a fix?  Maybe a key combination to enter in the UTILITY -> System Info screen to make it good again?

If not I think I'll have to returning to the supplier, hopefully they can fix it under warranty (or if not I will have to pay) by re-flashing or something....

Have you tried resetting it to 'Factory'?

[TerminalJack505]

You never really answered MetalFreak's question about whether or not that channel is being properly activated.  Those controls are shared by the two channels so if you just start messing with them then they can, in fact, behave exactly as you describe.

On the other hand, there are (supposedly) secret keycodes that can be entered at the Utility / System Info. screen.  So you might have found some way to lock-in the settings or something.  You would think that resetting to factory defaults or going through the self-calibration would revert the changes.

Edit: I wonder if you're in key lock mode.  You might try one of the unlock hacks.

hi ant452: I have the same issue with you, how to slove it eventually?

[BTO]

LOL
hi guys, i thought i should jump in here, since your talking about Hacks and Keycodes and sounding a little unsure of yourselves.

I've got a DS2072A
I've upgraded mine from 70MHz to 300MHz and Unlocked all the Trials

I've thoroughly researched the process for the DS1000 Series and the DS2000Series and the DS2000A Series

I can help you

Regarding this issue,

the same issue was presented in the DS2000A Series , a Firmware Update from the first version , i think 00.00.01 fixed the issue

so.. i suggest doing a firmware update of your scope

hacked or not, you have 2 seperate issues here

1. Update the Firmware to get rid of Your problem (it's a known issue and Rigol has a fix for it)

2. if your looking to "Hack" Your Scope,  that's another Thread,  or you can PM me.

[leyyer]

I didn't hack my deivce, but has the issue. I return my device to rigol, rigol may fix the issue.

[mimmus78]

I had mine fixed with unconventional and unprofessional way (vigorous slap). Since than it always worked without any problem.

My speculation is it was caused by some dirty inside some rotating encoder ...

[BTO]

Yep. A Good Ol Slap DOES seem to work from time to time

AND  that's actually a proven fact.  LOL

it doesn't hurt either
because  TECHNICALLY SPEAKING  you didn't break the Warranty seal.. did you

so if you slap it and you break something , it's covered under warranty   LOL

[mimmus78]

I noo!!! I forget about breaking warranty seal when it was in warranty. Now it's too late.

If knobs/buttons are doing the wrong thing it sounds like a bad connection on one of the cables that connect the main cpu to the front PCB containing all the controls.

It's likely multiplexed, so shorts/missing connections would cause all sorts of odd behavior.
I'm guessing its a flex cable so a bad connection is quite possible.

If hitting the scope has fixed it for some people that further suggests a bad connection

[mimmus78]

Yes, bad connection seems better explanation than dirt ... God only knows why it's still working after two years.
