Hello Harvey, Though my own 54522C is actually stuck out of work by some failure to initialize properly (described in previous posts), I have a wide experience using these scopes. Once, I got "jitter"

Can anyone send me a picture of an 8510C, preferably with a floppy disk half-inserted into the instrument. I only need a photo of that bit - not the complete setup. I would add, I want to use this for

Re: HP 54542C Scope

Re: HP 54542C Scope
Do you see the same effect if you go directly into the Auto Scale function with the sine wave signal? I have seen cases of instability when manually configuring the timebase, triggering, etc and yet

Re: 3325A/B vs 3324A
The 3325 is much more capable than the 3324. I can't think of any advantage that the 3324 has over the 3325 other than it looks more modern.. Originally the advanage was lower purchase cost. Robert
