How to calibrate probes for Advance Instruments Oscilloscope OS 1000?
(1/3) > >>
wa7son:
Thanks to a fellow EEVBlog user, I have an Advance Instruments OS 1000 oscilloscope. I bought two passive probes as it didn't come with any, and have since learned that I better calibrate the probes against a square wave signal generated by the scope.

Question 1:

The OS 1000 scope have two calibration sockets labeled "CAL 1V" and "GATE 10V" respectively. My first gut feeling told me to use the "CAL 1V" socket, but from reading the manual it seems "GATE 10V" is more appropriate as it's synced to the horizontal sweep (see attached picture from the manual of the OS 1000A model, which I think is similar enough to be used for this). Any ideas?

Question 2:

Normally I would expect two separate points on where I could hook the probe tip and ground clip respectively. But I'm not sure how to use any of these sockets. They look like the female end of a small banana plug - but I'm not sure (see attached picture, bottom right). Anybody knows?
Simon:
The test output does not need a ground as the test output and oscilloscope input have the same internal ground. Sounds like you should calibrate at 10V. Make sure you use a non conductive screwdriver/twiddler to make adjustments.
wa7son:
Thanks Simon

Have you ever seen these type of calibration sockets before? I wonder how I would connect the tip of the probe to it...
Simon:
one is called cal and the other gate, surely you use the 1V "cal". Those look like 4mm sockets so try a banana plug and clip your probe to it.
wa7son:
Thanks again :)

I don't have any lying around, but I'll head to the store tomorrow to buy one and try it out
