DC coupled 2.7 GHz Active Probe Project - Now Available!
lasmux:
I'm super proud to say that at long last, these are available at the site:
http://www.lasmux.com/product/single-ended-active-probes/
The datasheet has also been extensively updated, so worth checking that out!
It's surprising how much time and effort it is to get something like this up and running. Production issues, delays, customs and shipping, fighting insurance companies... the list just goes on and on. My hourly wage for this first batch, even if I exclude the 1.5 year long design work, is very, very low. Hopefully the next batch will be smoother.

Nice effort & probe, well done :clap:
If/When we need an Active Probe we'll order one :-+
Best,

I think one of the biggest things I've learnt from this project is that manufacturing (more than one-offs) things which aren't just straight PCBs is really hard, despite having some R&D experience in many of these aspects. It's also been surprising how long seemingly trivial tasks take. I had a bunch of estimates on how long various tasks would take for each probe. Pin assembly, testing, customs paperwork, etc. For almost everything I've underestimated the time requirements, despite having some experience in all of these things in the past.
I have been thinking on ways to improve my workflow for subsequent batches, including test jigs, and assembly jigs for the pins. It's definitely tricky as these kinds of tooling jobs take time to set up, and the time-saving payoff will take a while to reach.

Lasmux has provided me with one of his new probes to review. I gave it a quick check and everything appears to work out of the box. The bug rug was not supplied with the probe. I added it for a bit of insurance.
As always, if there is something specific you would like to see, feel free to ask.

Making some progress on the review today. The probe came with baby papers (data from the mfg) which included S-parameters. I had asked Lasmux to provide more details about their setup and have asked that they make this public. Shown is the setup I am using.
