Front Panel Arrives

A project log for 10MHz Rubidium Standard

I have a working Rb 10 MHz oscillator, so why not give it a nice home?

I used Front Panels Express to fabricate the front panel for my standard. I received the panel on Friday. Wow! Very nice indeed, much better than my normal acrylic panel attempts.

It took a couple hours to install all the switches and LED and connectors to the panel, but when it was done, it's all working.

...well, sort of...

The comb generator, which I hadn't tested much because it's sort of the "low priority" item, has an issue with some of the comb rates. I suspect it might be in need of a bit more bulk supply bypassing in the 74HCT151 mux chip, but that's just a guess. There are some "runt pulses" into the 74AC74 pulse generator FF that cause it to double-trigger. weird.

I've been using PCBs for front panels. I will have to look into Front Panels Express to see how they compare.
