Re: edelay vs ELECTRICAL DELAY and other fun
#internals
Why not use a dash after the data command to enable extended features.
For example:? data - x y z
If there is no extended data command then it will return an error with the dash.?
Or...the firmware

Re: edelay vs ELECTRICAL DELAY and other fun

I agree that edelay >>affects results<<. My point is that standalone device users seemingly
cannot display current edelay >>setting value<<, e.g. when RECALLing another calibration.

Re: Question on

'gamma' is no longer standalone in firmware that I use; neither in
help or from the shell.
Unrecognized text strings provoke the shell to echo with '?' appended
Probably only the shell handling

edelay 200 picoseconds visible very good, especially at high frequencies, above 200 MHz.

Re: edelay vs ELECTRICAL DELAY and other fun

You can notice difference on Series and Parallel RLC screen. Higher frequency has higher difference. 10 picoseconds is a small delay for NanoVNA you may lose difference in the noise.

These are debug commands, used to debug the code. Just ignore it :)

Re: Question on

Tks Oristo,
When a command no longer serves a purpose, like "gamma", why is it still in firmware taking up valuable space? Just a rhetorical question.

For USB device to support SPP (virtual COM port), it must be prepared
to send many bytes, so STM32 needs a buffer.
Unlike other chips, STM32 integrates USB. That is why it can

Re: edelay vs ELECTRICAL DELAY and other fun

FWIW, I would prefer 'anydata' over 'dataall'
That eliminates much host script foo, so great IMO,
particularly if it works with scanraw averaging.

Re: edelay vs ELECTRICAL DELAY and other fun

Changing edelay from 10 to -10 by shell makes no noticeable change on DELAY format
with a prominent reflection pulse and marker around 250MHz.
50x larger edelay values visibly shift the trace

I'm slowly working my way through understand all the Wiki shellcommands. A couple of the consolecommands aren't clear to me and I was hoping you might be able to help.

we can implement this feature for current "data" command, so it will be able to return all requested data in a single response. But unfortunately I don't see easy way on how to determine if firmware

Hi Rune, you can check firmware capability with help command. It returns list of supported commands. So, you can check if specific command is supported by this firmware with simple string word search

You can find ELECTRICAL DELAY with touch screen with using DELAY format for the track. It shows Group Delay in picoseconds. But you can change scale to 5 ns, it will be more conveniently to use with

Back to the original subject issue:

At least for this firmware version,
there is a disconnect between negative values by shell and screen menu
