Title: Tek T953A unstable triggering
Post by: Axtman on July 18, 2023, 10:22:24 pm
I recently picked up a Tektronix 935A 35MHz dual channel oscilloscope for cheap. It is clean and everything appears to be in good working order. The only issue is I cannot get the test input signal to stay put. It keeps wandering horizontally. I know that Tek scope are noted for their stable triggering. Any help would be appreciated. Thanks.
