00:11 <awygle> and you can do "multi-channel design" with multiple references to the same schematic sheet but you can't do "rooms" without a plugin making it mostly useless in vanilla kicad

01:06 <azonenberg> electronic_eel: the names are in the repo if you forget :p

01:12 <azonenberg> The external trigger will go through basically a LA input stage. That has always been the plan

01:12 <azonenberg> sorry i wasn't clear

01:12 <azonenberg> i'm not offloading TCP to the stm32 because i need to be able to push tcp at >1 Gbps from the FPGA for waveform download

01:13 <azonenberg> there will likely be a software stack, perhaps lwip, on the stm32 for the management interface

01:13 <azonenberg> but that will not replace the fpga tcp for waveform streaming

01:17 <azonenberg> awygle: yes good multichannel design in kicad is notably lacking

01:17 <azonenberg> electronic_eel: so how exactly are you planning to do this opamp attenuator exactly?

01:17 <azonenberg> something that runs on +/- 24V?

01:37 <azonenberg> also ADC test board just went to fab at oshpark, eta april 15th

01:39 <azonenberg> (the panel took longer to fill up than usual)

02:12 <azonenberg> Sooo i just got a fun idea for a highish speed probe apparatus

02:13 <azonenberg> i wonder if you could design, out of 3d printed + commodity parts, something along the lines of an ezhook

02:13 <azonenberg> but with a damping resistor right at the tip as close as you could get. To minimize unterminated stub length

02:36 <azonenberg> That might be a fun design project lol

02:37 <azonenberg> The standard ezhook is probably around (just guessing) 70mm long, so even if you have a buffer/resistor right at the end, you're limited to about 300-400 MHz

02:37 <azonenberg> and if you wait until you get to the LA pod, not more than ~100

02:54 <azonenberg> also my 75R's are now eta thursday

05:48 <azonenberg> the big difference is that the external trigger input will be a 50 ohm input and not whatever higher impedance the LA's use

10:23 <Degi> Hm you could put a logic buffer into the tip of the probe

11:04 <azonenberg> Degi: what sort of buffer, and how would you place/power it?

11:05 <azonenberg> anyway that sounds like something to think about for a next-gen probing system

11:05 <azonenberg> CONWAY is going to be relatively dumb and low speed

11:06 <Degi> Hm some tiny IC and maybe with tiny wires going to it

13:52 <noopwafel> heh, passing -h says to use --help and passing --help does nothing :-)

13:52 <noopwafel> (reading docs now)

13:53 <azonenberg> noopwafel: lol

13:53 <azonenberg> yes, there are definitely some rough edges

13:53 <azonenberg> it's very much a work in progress

20:12 <electronic_eel> azonenberg: in the starshipraider readme you write that CONWAY will have an SFF-8088. I thought we'd go with SFF-8087 because the sideband is missing in the '88

20:13 <electronic_eel> also the LVDS part there is maybe a bit misleading, it is about the interface to the scope, but you could mistake it for what it is designed to probe

20:13 <electronic_eel> probing LVDS would mean differential probes and also higher speed

20:14 <electronic_eel> unfortunately I didn't have time yet to further think or simulate the LA AFE

20:16 <electronic_eel> in the agilent/keysight appnote I linked they listed some resistive wire for use with their probes. I think this works very similar to the resistive wire that is used in common passive 1M scope probes

20:17 <electronic_eel> unfortunately building grabbers with such resistive wire as grab fingers won't be easy in small scale manufacturing

20:25 <Degi> Maybe resistive plastic can be used?

20:38 <Degi> Hmmm, 5 HMCAD1511s cost about the same and have about the same performance as a LM97600 while having lower data rate per lane and more configuration options...
