Wavetek 159 Function generator
« on: May 09, 2017, 01:37:32 pm »
Helo everybody!
I recently bought a Wavetek 159 with some problems. I'm new to TTL so I want to ask for some help.
My problem, is that the instrument not responding for the keyboard properly. Firstly I thought maybe there is a dirt problem, or a problem with the keyboard multiplexer. What is happening when I press something, is that a nother function is responding, like somebody changed the keys. (They're in place, of course). For example when I press amplitude, the offset can be changed. Sometimes 1 turns on 6 turns off the display. There is not even a button for it. And what is the most interesting for me, is that for every even number 8 shows up, and for every odd number 9 shows up on the display. Only the minus sgn works properly.
