![]() ![]() The problems that I have are with the horizontal part of the oscilloscope. ![]() 1khz and 4mhz generators are spot on with digital scope and dmm. I don't have a function generator so I used the 1khz signal from the digital scope, I had another 4mhz tcxo and 16mhz from arduino crystal I only used the 16mhz sine wave for trigger calibration as that's not that reliable. I followed the calibration procedure about 4 times until I understood what was happening, and I got everything right. This is my first scope (somehow, as I just got a digital one as well so it's a first for me anyway). Voltages are very close to spec: 5v - 35mV ripple 55.74V - 47mv ripple 15V - 29mv ripple -8V - 10mv ripple 112V - 30mv ripple. I could get it to 300mV but there's nothing on frequency adjustment in the manual. Calibration signal was about 270mV with 960hz. After a few tests it was clear that I need to recalibrate it. Perfect cosmetic condition, came with original service manual, pouch and a blue screen (I don't know what that's used for, there's already a clear one installed, and a metal mesh in front of that). ![]() I got a Tek 465 scope from ebay and I was surprised to see that it worked with no problems. ![]()
