Front panel for 29.5 MHz amplifier box |
|
|
I made a tentative front panel design for the newly installed amplifier box. I used this chassis diagram to place the holes for attaching it. I just made the dimensions match the front of the chassis rather than extending out to the sides since the front panel doesn't need to screw into the rack; the chassis is mounted already with separate brackets. For the connector holes I used a caliper to measure the feedthroughs I'm planning to use and added ~.2 mm to every dimension for clearance, because the front panel designer didn't have their dimensions built in. Please let me know if I should do something else.
The input and coupled output will be SMA connectors since they are only going to the units directly above and below this one. The main output to the EOM is the larger connector with better shielded cables. I also included a hole for a power indicator LED.
EDIT: I added countersinks for 4-40 screws on all the screw clearance holes.
Johannes, if you're going to be putting a front panel order in soon, please include this one.
Also, Steve, I found a caliper in the drawer with a dead battery and the screws to access it were in bad shape- can this be fixed?
