But I don't think the annoyance of the jitter would be related to the frequency of the input signal (or DUT).
Thanks for this interesting video. I was just struggling with an I2C problem, and learned a few things how to optimise use of the segmented memory (bummer it will not decode in analyze mode, maybe in the next FW update?). Maybe I should fire up the hex editor.
Looking forward to seeing this functionality in RUU.
Thanks Mark
That's a good trick to search recorded frames of data
It is great that you will incorporate it in a future version of RUU.
Here is a tip to use with manual Hex editing; I think the hex editor will fill a selected data block with a given byte pattern. That is fill 240 bytes with x' 21 3C E1 FF' repeated to fill the block, for example. That is what I used to patch Rigol waveform files. I hope that will help until RUU.
Thanks again.
kinda annoying and I don't know why this happens all of the sudden: I power off my DS2072(2302) normally and pull the plug. Now, whenever I put it back in the next day, the DSO resets itself (like it does after self cal for example)
the 2nd problem is about measuring. I try to measure/calibrate an ECG circuit, setting it to 5 mV/DIV. If I don't use high res, it's really impossible to measure
I tried both, "default" and "last" in the settings, it happened with both (more than 1 try for both settings)
I'll give it another try
the 2nd problem is about measuring. I try to measure/calibrate an ECG circuit, setting it to 5 mV/DIV. If I don't use high res, it's really impossible to measure anything.
increasing the time base to something like 10 ... 100 ms/DIV makes the DSO totally slow, no matter what sample memory I select (the lesser the memory, the weaker the visibility of the curve on the screen)
I still remember my old HP DSO which was nothing compared to the Rigol and I was able to measure and display what I wanted to.
What do I have to do to get a nearly clear curve on screen?
I can't see an ECG curve on the Rigol because it refreshes so slowly :/
1) As others suggested, use roll mode. This is what I usually do for my slow measurements (and I've had it all the way to 1000s/div!) Hires is really good in roll mode.
2) Set the trigger point to exactly the left side of the screen.
In normal y-t mode, the scope needs to have captured enough data to fill in from the beginning of the waveform to the trigger before it can actually trigger. So if your trigger is in the center of the screen, and you're at 100ms/div, then the scope needs to have 700ms of data before it can arm the trigger. By moving the trigger point to the left of the screen, the trigger can arm "immediately" after the previous waveform is captured. When the time base is slow enough, the scope will even display the in-progress waveform, making it feel a lot more responsive.
I know this might be a bit off topic, since we're discussing the 2000 series scopes,
Has anyone noticed any vertical amplifier offset (no signal applied with 50 ohm termination on input AC or DC coupling selected) in the range of 100 - 200 uV when in the 500uV / div range. I also noticed that channel 1 has a bit more than channel 2. My particular model is a DS2202, are we splitting hairs with a Chinese scope playing in the grass?
In the attached screenshot, I have my trigger position set to screen left as you suggest - but it would still take 7 seconds before the buffer is filled (and I would start to see the trace). So you have to keep an eye on the location of your trigger position within the current sample memory depth - not just the screen memory.
I think I may have found a bug. Since upgrading to 3.00.01.03, whenever I plug in the scope, it automatically powers up. Before it just used to fade the power button. The power mode in the settings is Default, not Open. I did try both. Going back to V2 did not fix the issue. When I turn the scope off and unplug it it takes a few seconds for the power led to completely turn off. If I then plug the unit in, it boots up on its own.
I went back to FW 00.01.00.05 and main power connect still starts my DS2072
I use SCPI command to get to LAST
