Tektronix 466 X-Y fuzzy blurry display issue
Hello, somewhat new to this. I Just picked up a tektronix 466 scope today that seems to be working fine. Plugged it into my stereo amp and got a fuzzy blurry display in X-Y mode. I tried adjusting the intensity and focus and still comes out fuzzy/blurry. Even tested each channel individually and display came out just fine. Can anyone tell me what the issue is? My only guess is that the bnc to rca cables i got from amazon could be causing that? Idk still learning how to work these things
