hello members,
recently i managed to get my hands on a tektronix 577 curve tracer.
after fixing the power supply i made a first attempt to see the traces of a transistor
here is the result: see picture
can someone point me in the right direction, what do i look for next?
many thanks

You definitely need to refer to the operator's manual for the device you are testing. There are a lot of settings that are critical to getting good readings.
But the first thing to do is exactly what you are doing - complete the adjustments/calibration. It does take time. Took me 3 hours to get close, then I took another 2 hours the following day. I replaced some capacitors and bad resistors in mine, and it's had 6 months of use maybe 6 hours a month, and one of the adjustments has drifted a little, so I'll be repeating all of them.
