05:03 <_whitenotifier> [scopehal-apps] azonenberg 9ba0582 - Use VCD import filter rather than legacy VCD code

05:58 <_whitenotifier> [scopehal] azonenberg cc3b1fd - Removed width attribute from channels as almost nothing cared about it or set it to anything other than 1

05:59 <_whitenotifier> [scopehal-docs] azonenberg d4f8a6c - Added skeleton doc pages for VCD and CSV import filters

05:59 <_whitenotifier> [scopehal-apps] azonenberg pushed 1 commit to master [+0/-0/±2] https://github.com/glscopeclient/scopehal-apps/compare/9ba058269c47...5c7051ac691b

05:59 <_whitenotifier> [scopehal-apps] azonenberg 5c7051a - Updated submodules

07:14 <azonenberg> ok so that's the first refactoring done: digital bus is a separate channel type and there is no longer a width property on a channel

07:15 <azonenberg> (the handling of buses needs to be improved in general)

07:16 <azonenberg> Now I can finish the VCD import refactoring, then I will probably write a VCD exporter

07:17 <azonenberg> And then I can work on the channel type moving

07:17 <azonenberg> Which will allow the CSV importer to support mixed analog and digital channels in the same CSV

13:12 <GyrosGeier> 17:51 < azonenberg> Can you PM me an email address so i can put you two in touch to discuss them becoming a maintainer for the package?

13:12 <GyrosGeier> sjr@debian.org

13:45 <azonenberg> GyrosGeier: sent

14:02 <azonenberg> Woo PRBS generator (and some cables I ordered to use with it) is out for delivery

14:02 <azonenberg> So i should be able to assemble and play with it tonight

14:39 <miek> azonenberg: here's some agilent bin files from my scope - https://assortedhackery.com/agilent_bin.zip

15:53 <miek> does anyone know of an open source TDR/TDT demo board out there?

15:59 <XMPPwocky> as in just an AWG or something glued to an ADC? or do you want something w the actual algorithms

16:02 <miek> oh, no, i meant as a demo target - a board that has a few different traces with features to measure, like steps in impedance

16:03 <miek> for example, keysight has this one: https://i.imgur.com/7sJfU4s.png which looks neat, but they want $1327 for it, lol

16:17 <Degi> I think there is one for testing DUTs and the impedance of the substrate

16:20 <Degi> Though for that price at least ISIG coating would be nice

16:42 <bvernoux> miek I have released a similar board if you are interested

16:43 <bvernoux> miek, except it will requires some modification to do TDR/TDT stuff

16:44 <bvernoux> https://github.com/bvernoux/kicad_rf/tree/master/4Layers_trl-board_v0_3

16:44 <bvernoux> It is a TRL board today

16:44 <bvernoux> What is expensive is the connectors and it is a key factor for TDR/TDT too

16:45 <bvernoux> What is missing is differential traces

16:46 <bvernoux> To do something similar to what Agilent sell for 1327USD

16:46 <bvernoux> The most expensive are connectors but at end you will have a board for 1/10 the price so about 130USD

17:13 <azonenberg> miek: i have some connector test boards

17:14 <azonenberg> but i would like to build one that has some various test subjects like diff pairs, mismatched lines, stubs, etc

17:14 <azonenberg> It would probably be $200+ to do right because i'd be using high end broadband connectors like the Rosenberger 32K243-40ML5

17:14 <azonenberg> and those are close to $10 each

17:18 <azonenberg> So you're looking at $20 per single ended or $40 per differential test subject

17:18 <azonenberg> plus board cost

17:19 <azonenberg> i would love to design one and open source both the PCB layout and EM simulation results from the board
