HP 1821a issues
 
Hi,

the 1821a double time base in my old HP 184A oscilloscope mainframe has got some issues. Switched to three of all the sweep frequencies, the beam doesn't start at the left edge of the screen, but about 1 cm right from it. The trouble shooting scheme at page 50 of the related manual tells me to check the transistors Q210 and Q211 and CKTS. What does CKTS mean?

Best regards!

'CKTS" I would assume is short for "circuits". I guess they mean look at the circuitry involving Q210 and Q211. I used to fix HP analog scopes way back and they were a royal pain to fix. HP analog scopes had lots of issues!!

Good Luck
Rick
