Magnova oscilloscope

Do you want me to mark them in a special way such that you know which one relate to MAgnova? For now I created this here:

Thx for the feedback @Xyphro!
If you have more reports, better add them as comments to the Magnova Driver Pull Request here: https://github.com/ngscopeclient/scopehal/pull/1031

I've updated the Batronix Magnova driver for TestController. This version now includes an Other button to execute a QuickSave remotely. Available here.

Thanks,
Josh

I think these are great new features, thank you very much for providing the update. However, I would like to reiterate my proposal to add a normalization feature for Bode plots which I already made here. It would be fantastic if you could add that. 

Thank you for the reminder and the positive feedback on the firmware update.

The Bode plot normalization that you suggested is a good idea, and it is still on our to-do list. We plan to implement it, but we ask for a bit more patience as it will be included in a future update.

To give you a quick status update on your other suggestions, the "Bode plot cursors" and the "amplitude scale for the generator" have already been implemented. The remaining suggestions, "trigger hysteresis indication" and "set to next peak left/right" for FFT markers, are also good points and are planned for a future update.

@Batronix,

Thx for the firmware update, the new decoding view is very nice.

I am not sure if this was allready meantioned in this thread
but the cursor functions could be improved.

When I try to measure a time difference, the cursors should stick to the actual x-position
during a change of the timescale or during change of the timeOffset.

Lets say I put cursor "A" to -10ms (at a rising-edge of a signal) on a timescale of 10ms/div.
At the moment, when I change the resolution to 20ms/div, the cursor is then at -20ms...10ms away from the rising-edge.

I would prefer that the cursor is moving with respect to the analog channels, also when the offset is changed.
(the same goes for the cursor on the y-axis e.g. to measure a voltage difference)

I am not sure if my explanation is somehow understandable :-)

Hi John,

Thanks for your feedback on the update and your suggestion about the cursors.

Other users have requested this as well — to have the cursor reference stick to the actual time and voltage values rather than the screen positions. I agree that this would make cursor measurements more practical.

I can’t promise that it will be implemented in the very next update, but it’s already high on our priority list and should be included in one of the upcoming releases.

Hello,

I've just published a new build of Ngscopeclient with Magnova driver (Github login required):
- Windows : https://github.com/fredzo/scopehal-apps/actions/runs/20429605897/artifacts/4942554667
- Mac (ARM) : https://github.com/fredzo/scopehal-apps/actions/runs/20429605887/artifacts/4942404333
- Linux (Ubuntu) : https://github.com/fredzo/scopehal-apps/actions/runs/20429605911

This build should fix deadlocks (application freeze) reported by @Xyphro.
It also adresses scope/application Time Scale / Memory Depth / Sample Rate synchronization issues.

Known limitations :
- For now, Magnova's SCPI implementation does not support digital signal acquisition,
- Selecting specific Arbitrary waveform from function generator is not possible either yet.
- Time Scale / Memory Depth / Sample Rate synchronization only work if the scope is in "Extended Capture" mode (Acquire menu).

For the record:
When running ngscopeclient for the first time, you will have to go to “Add>Oscilloscope>Connect…” then give an nickname to the Scope (e.g. “Magnova”), select “magnova” driver, select “lan” transport and set the “Path” to Magnova’s <IP>:5025.
For next launches, just click to “Add>Oscilloscope>Magnova”.

Any feedback / bug report is welcome!

Cheers,

Fredo.
