T904 board

Started by John Larkin August 8, 2019
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 .. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

It's in a box now. https://www.dropbox.com/s/sy6nu3732d7fspb/T906_Top.JPG?raw=1 https://www.dropbox.com/s/nsuvj8bgvhglqot/T906_Front.JPG?raw=1 That's a nice Hammond rack-mount box, all made from extrusions and a couple of flat top and bottom plates. https://www.digikey.com/product-detail/en/hammond-manufacturing/RM2U1913SBK/HM999-ND/2094736

Very pretty. Who printed the front panel? Cheers Phil Hobbs -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC / Hobbs ElectroOptics Optics, Electro-optics, Photonics, Analog Electronics Briarcliff Manor NY 10510 http://electrooptical.net http://hobbs-eo.com
