T904 board

[John Larkin]

Here's another big board.

https://www.dropbox.com/s/bfepc9wsaxwgs8p/T904_PCB_1.JPG?raw=1

This is the main part of a test set to production test a laser
controller.

Upper-left is a MicroZed, which is the compute/FPGA and communications
bit. Upper right are a couple of the cute LTM switcher bricks.

This connects to the DUT, an oscilloscope, a DVM, and a Keysight
counter, so there's nothing on this board that needs calibration.

There are a bunch of TDR test traces and SMA connectors, just for fun.
I'll populate them on the solder sample board. I can probably just
push on them sideways to connect for a second, no need to solder.

Anything like the one I used to test ? 150A @ 85V LED laser array and
3k3V Q switch... sweet as you like ..

Post a pic!

It's in a box now.

That's a nice Hammond rack-mount box, all made from extrusions and a
couple of flat top and bottom plates.

Very pretty. Who printed the front panel?
