Correction...input loading has an effect, or rather the compensation selected for either Hiz or Loz has an effect..

So a square wave generated by the AP is confusing....as to it's value...coolness. I need more uncertainty running this thing!!

I know the feeling. After 6mos of using it I'm really just beginning to scratch the surface on understanding the Sys1. Mines a standard 22A so no dual domain and I have most options but no burst module so no internal squarewave capability in mine.

I've had mine for 4 years and getting to where I can run a battery of tests without the book finally...

True dat...
Did you ask him why I'm getting 1.4 in on 1.0 out?

RMS out vs peak reading in?? Wild guess given the ratio you are reporting.

 

[laatsch55]

That's the consensus Joe...

Probably wouldn't hurt to independently measure what the gen is actually putting out... and in that way you sort out what's what - an output problem or a detection problem... or worse yet, both.

I've never fed a square wave into mine so you had me wondering. I set up a 2 Vpp 1kHz square wave on my scope from the func gen and then fed it via unbalanced BNC to the AP. It measured as expected,,, 2V.

Yeah, I'm not surprised by that. By the time the 'Sys' platforms came into being, with the APWin and all, I'd imagine AP got their s h ! t together.

But what I was driving at is what the ATS based gens actually put out vs. the panel control settings...

Had an Acurus amp under test I see...

I've got an old Eico 377 sig gen, I'll try that tomorrow...

 

[laatsch55]

Fuck, I've got two scopes myself..

Did you build it from a kit ... as a kid ?

The AP doesnt make a very square square wave, or I cant run my scope ..

 

[laatsch55]

I just realized I have no idea how to output the scope...

Dude - those things are like museum pieces in good working condition & clean on the outside.

 

[laatsch55]

The scope and the AP agree on frequency..

 

[BlazeES]

That's because you have the EDU version of TDS ...

 

[laatsch55]

I have an old 950 cap checker too with the tube for an Indicator light..

I thought it was appropriate..

 

[BlazeES]

At least you got one with a USB port on the front ... and not one with a floppy disc drive.
