Problem with trigger at 20us / 10us

Post by Johncoffee »

I have a running DSO shell - all works fine except:

"triggering/ display of 5V pulse signal with 100µs length that repeats every second:

- works at 50µsec and above
- doesn't trigger at 10µs and 20 µsec time setting or at least the pulse doesn't show. I'm getting a 0V line only


Any guess what could be wrong?



Thanks
Stephan

When timebase is set to 10us or 20us interpolation is used. The trigger will not work as of current firmware. We are working on it to improve. Hopefully this issue can be solved soon in new revision of firmware.
