Finally got the manual for my Protek 6502 scope and started working with it. Testing it's ability to "read correctly" Started by using home built signal generator with 455k signal, from my DMM I can measure freq but with the scope it was like 55k off of the desired freq?
Using this scope to measure freq should it be exact? Should I have it calibrated? Should I purchase the service manual and calibrate it myself or leave it to professionals? Finally and recommendations for a shop that calibrates scopes.
Thanks!
