Hi CS,

Looks very similar to the issue I had. See thread:

Does Tr. Mode > SINGLE not work for your needs?

Hi owenix,

I never got around to doing anything about it yet. I find my DSO too useful to give up for the time it will take to return it.

I suspected some of the gates in U9, but since I have only the DSO I was unable to confirm that, not wishing to try to use it on its own circuits.

Hi Ben,

I re-upgraded and could not reproduce the issue. We'll have to put this one down to an upgrade glitch.

I'll keep an eye out for it happening again.

Thanks again for another very useful upgrade.

Ben, thanks a million for the upgrade, but is there something funky going on with the ground position?

A signal that I measured before as having no DC component now has a significant offset.

(and downgrading returns the signal to the expected state).

Maybe I just need to recalibrate?

Ah right. I misunderstood you.

Thank you for clarifying that for me.

Will I be able to use the DSO Nano V2 to analyse 100kbps I2C? I imagine that 400kbps I2C would be beyond the DSO Nano's capabilities (I seem to recall an HP document suggesting that you need something like 5 times the sample rate as the bit rate you are trying to measure to get reasonable fidelity ...

You should be able to move Gnd Pos anywhere you like as long as you don't push trigger level (+/- sensitivity) off the screen at the same time.

Ben, I am unable to do this and would like to. Gnd Pos is firmly locked inside the visible screen. Am I missing something to enable it?

I can't tell 100% from your images. The disconnected image *might* be normal, depending on your settings. My Nano does show some noise at the most sensitive settings, as do all scopes. There is glare in your photos obscuring the settings. We'll do much better if you post BMP's directly from the Nano...
