Unlike many of the power supplies and voltage sources I have, the Keithley 230 is capable of operating in all four quadrants, meaning it can both source and sink current in either of the output polarities. Although the current capability is limited to ±100mA.

I got this unit next to nothing as it was not working and I was told that multiple boards might have failed. Even though it might not be repairable, we can still learn quite a bit from a teardown. If you just wanted to watch the teardown video instead of reading through the post, you can scroll down to the bottom. Continue reading ‘Wavetek 859 50 MHz Pulse Generator Teardown’ »
