I have a tektronix 1225 logic analyzer. I like it, but the keypad is driving me insane. It seems to have extreme bouncing on the switches. When I press them it will register as pressed twice or three times.
I took the keypad assembly apart and started probing around. See the picture for reference: the first ones are the output to the I/O board and the second one is the switch and the output of the Schmidt trigger along with a good switch.
On top of that I took one apart and the switch jumped out and decided to hide. I think that I should replace these switches. I don't know where to find replacements though. Anyone would know?
