DC coupled 2.7 GHz Active Probe Project - Now Available!

I'm organising an initial manufacturing run of a batch of 25 PCB assemblies now. Going through some normal back-and-forth with the assembly house over some of the details.

Nice.  Just let me know when you are ready.

Hi lasmux,
any info about when the probes will be available ?

Soon. Did I say that last time though

In other news, I have the first batch of 25 PCBs here (at long last) and the first couple have tested fine!!


I've also spent what felt like an eternity soldering together a mountain of probe tips. Each signal tip is in three parts. There's a pin to go into the probe, a series resistor, and then a sharp tip, all cut down and then soldered together. This is then carefully glued for rigidity, and finally tidied up with some semi-rigid heatshrink. 10 minutes assembly per tip. 50 tips. I've managed to burn through every decent podcast I know of. Fortunately the ground tip sockets are a bit simpler to assemble.

I'm super proud to say that at long last, these are available at the site:

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 

If/When we need an Active Probe we'll order one

Best,
