ATTEN 1102cal proble when using trigger in single mode

[iostrym]

Hi everyone,

I read some stuff on this forum about ATTEN 1102CAL oscilloscope. I know original firmware may have problem but it's not mine and I can't update the firmware.

for instance here :
https://www.eevblog.com/forum/reviews/atten-ads1102cal-trigger-uncertaintyjitter-problem/

but it is very specific whereas i'm looking for doing something really evident.

I juste wanted to check because I would like to know if I'm facing a firmware bug problem or if I don't know how to use the oscilloscope.

In fact, I don't succeed to make the trigger working in "single" mode.

I want to display the rise of power up on a signal that will rise from 0v to 12V. I can display it at 0v, then I power up my circuit and I can see the signal at 12V.

I configured the trigger in single mode and I wanted the oscilloscope to trig when the voltage rise a bit. for instance I set the trigger at 1V. but in single mode, the trigger never trig...

do I miss something important ?

I have seen this video :



I remember that ATTEN 1102cal has the same firmware than SDS1102CML+ (or SDS1102CNL?) so they are pretty identical.

what I have seen in this video is identical to what I have tried so I don't understand why it didn't work in single mode.

it worked, I guess I didn't correctly configure the trigger that has a AC or DC setting...

I successfully did a lot of observation but I don't succeed to do one.

do you know if I could observe a clock signal around 100 Mhz and trigger the 12V signal of the alimentation ? clock signal should be approx 3.3V

during my first observation I have the feeling that the clock signal generated a lot of noise on the other channel.

my goal is to observe the generation of the clock when the 12V is rising...
