<Degi>
Is there a usable cheap VNA which can do like 1-500 MHz?
<azonenberg>
The nanoVNA does 10 kHz - 1.5 GHz iirc and i've heard good things about it
<azonenberg>
it's not full 2 port, it only gives you S11 and S21
<azonenberg>
and i doubt dynamic range etc is great
<azonenberg>
But people seem to like it

[scopehal] azonenberg d2311b5 - TektronixOscilloscope: implemented Get/SetTriggerOffset(). See #13.
<_whitenotifier-f>
[scopehal] azonenberg f00c551 - TektronixOscilloscope: Implemented Get/SetDeskewForChannel(). At this point basic functionality for analog-only usage works. No advanced triggers supported, only edge. No digital channel support. Fixes #13.
<azonenberg>
I'm going to call this minimum usable functionality now
<Degi>
What is full 2 port? S22 and S21?
<azonenberg>
Yeah
<azonenberg>
So basically it can only transmit on port 1
<azonenberg>
but receive on both
<Degi>
So I could essentially swap the cables and then get both measurements
<azonenberg>
Correct
<Degi>
Sounds good to me
<Degi>
Oh cool, the tek driver is working now
<azonenberg>
And then write some code to postprocess the two s-parameter files to merge into one s2p
<azonenberg>
Minimum functionality, and not tested on older instruments. in fact i *know* it wont work on anything that doesnt report itself as an mso5/6 because i hard coded *IDN? checks for them
<azonenberg>
and most of my code is gated off for any unknown device
<Degi>
How long does each acquire take?
<azonenberg>
i've seen hints that mso4 may work on the same protocol but i don't want to commit to anything until i've tested
<Degi>
It is over a WAN right?
<azonenberg>
Degi: over a VPN that's >100ms round trip? 3-4 seconds for 500k points lol
<azonenberg>
i expect locally it will be almost as fast as lecroy
<Degi>
Hmm, should compare that to the rigol... heh (though IIRC the rigol can sometimes get a few FPS)
<azonenberg>
Perhaps a bit slower as it seems to not like batching
<azonenberg>
but that could also have been some older bugs i had, or the WAN being derpy
<azonenberg>
I'll try to optimize more when i get hands on time on one

Degi: I'd ask bvernoux about the nanovna 2. I think he has one and also knows which models are from the original designers and which ones are clones
<Degi>
Okay, I'll do that when they're online

do we have a hard dependency on GOMP or are you wanting to make this work with other OpenMP implementations as well? I looked at the libgomp source code and found what looks to be a way to programmatically set the wait mode to PASSIVE
