I’m having the same problems as Ben. Triggers don’t work apart from in AUTO mode. NORM and SIGN/SING mostly don’t display the triggered signal at all.
Sometimes in NORM mode, when the R/S button is pressed and HOLD is displayed on the screen, I can see the waveform moving.
Sometimes it does trigger, but only after HOLDing, and possibly only after holding while the signal level is low if you’re looking for a rising edge. It appears to work better at longer time bases.
SIGN mode doesn’t work at all for me, unless I press the R/S button and immediately get a trigger. Could it be that these are triggering further along the horizontal axis and are therefore out of view?
I’m using firmware version 2.21. To test SIGN and NORM modes I was manually triggering the signal level rather than putting a waveform through it.
Hope that helps, and I look forward to the next update!
