Oh, well, my Scope, is a Textronix's 475A but I have no interface on it. not even HP-IB (GPIB or IEE-488 ) and normally it would be a waist as Im moving the probe(s) all the time. ~~ Cris H

What I havent figured out how to do yet is save as a wave file.
(did manage to save 1 second, but not more. )
anyway, in saving as a wave file, theres a huge number of tools to do analysis.

Hi Gough,

Good presentation,

I saw in the video you are using tightvnc or similar for remote access, I do not know weather Tektronix has their own version of software for remote access.

Humm I seem to recall watching the video before. Maybe a pre-release. No matter, is was great to revisit it. It triggered a memory of my first experience with automation.

Transport Canada had just purchased a replacement communication system called MACS. Module Air-traffiic Communication system (I think? 25 years ago.). It was the system that linked the air controller to the radio equipment for both transmit and receive.

It promised automated testing. Using scripts the audio test set could provide tests on channels. In the past the tests were done manually flipping nobs and throwing switches. Imagine all that being done automatically.One example was if you failed to change the impedance from 600 ohm to infinite during some tests you would get the wrong reading. (Air-traffic controller complain when audio volume goes up by 3db without reason. Imagine this being done automatically.

I wrote my first script using ED and precursor to the vi editor and presented it to my work mates. "What are we suppose to do if it is automated? was their response." To watch Dr. GL video is mind blowing. A great trip down memory lane for me.

Remote control of instruments in general could be handy for diagnosing intermittent issues, especially across a large site where by the time you receive the fault report and get out there it is no longer misbehaving.

I cannot imagine having my act together enough to intentionally use a scope remotely BUT I am intrigued by the capability. I can see having a scope connected to circuitry and having a flash of brilliance in the middle of the night that this capability might allow one to explore. "What if we tried this?"
Other than that... it could allow multiple users to run the same measurements at different tmes - sort of like in an educational environment. At some point, someone has to connect a probe to a wire or terminal.

I have done some remote scope control as apart of a self-learning exercise, but I have not used it in any of my jobs. It just never seemed like the most effective approach. I am interested to know what compelling applications others are running into.
