I have a newish SDS1104X-E oscilloscope, and being an old noob, I am still trying to make friends with it.
Firstly, when I change/zoom in the divisions per volt setting, the waveform jumps off the screen and the position knob must be turned, until the waveform is found and re-positioned. This can require a lot of turns. Is there any function to set the location of the waveform and relocate it with the push of a button? If not, are there any tips to make this less tedious?
Secondly, even understanding that extreme caution is needed when probing, and trying my best not to touch the wrong thing, I did end up having a spark on one probe. I honestly don't know what happened, or where the contact was made. It did not leave any kind of mark on the probe and all the functions of the scope seem to be intact. The DUT also seems to be fine. So, do I need to worry, further?
Thanks for your help and support.
Not just your question but...
With offset setting it is some times frustrating when signal stay same but user need select other V/div setting.
This is why there Siglent added (time ago) one feature. User can select Vertical: "Fixed Position" or "Fixed Offset" (also same for horizontal)
Fixed Offset is default.
Fixed Position example:
If user have +3V dc signal and 1V/div. User see trace 3 div up from center (if offset 0).
If user now adjust offset to 3V so that trace is center (offset 3).
(0 level is now 3 div down from center.)
Now if user change V/div setting...what happen? If signal is enough accurate 3V trace stay center of screen what ever V/div user now select. (and zero line move more or less out from display) (this feature can also use indirectly for more resolution proportional voltage measurements in some cases due to fact that offset DAC have lot of more resolution than main ADC)
Fixed Position vertical ref is quite useful if need example look PSU ripple and still also can detect also more or less slow drift and jitter. No need turn or set again and again trace offset when change V/div.
And more, in same improvement time Siglent add also same function for horizontal position. So if want example trigger position left side (or where ever) then when change horizontal speed (time/div) trigger position stay fixed in user selected position.
Horizontal: "Fixed Time" is default but user can select also "Fixed Position" mode.
This is handy in some situations when need trigger position other than center and then need often change time/div (example with serial decoding very useful and in many other situations also) Also if user like left screen trigger position like old analog scopes, just use it.
Utility menu page 4, "Reference"... if I remember right (I have not now here SDS1000X-E for check)
ETA: Perfoma01 was more fast........
