Scope GPIB stuff

Aug 13, 2006 7 Replies

I have a Gould OS4020 digital storage scope which is fitted with a GPIB interface. I also have a 'Brain Boxes' brand GPIB translator thingy that, I think, talks to centronics and RS232 ports. And a small laptop with parallel and serial ports.



I don't know much about this, but I gather I can get stuff to happen if I connect them together in a meaningful way, and probably run some suitable software on the laptop. Something I'd like to do is capture a waveform in the scope, and then dump the scope's memory to the computer. The scope has a set of connectors on the side, including a couple of female D-type. I



*think* these have something to do with the storage functions, but I don't have the manual for the scope. Can data be dumped through the GPIB bits, or does that only tell the scope to dump directly from its extra connectors to the computer?

Can this sort of data dump be done? If not, what could I use the GPIB stuff for?

I have manuals for other Gould scopes as PDF (notably OS4000 and OS4040/OS4041, which are similar models). Turns out that the extra output connections are Option 4001, but they only mention a data sheet for that - I'll keep digging, though.

might be of interest. Don't know whether it supports your interface, though.

Thanks for that - the command line diagnostic tools could be handy. I have the docs for the interface, so a read of that and the toolkit docs might be in order.

Depends entirely on the design of the scope, as every GPIB device will use the interface in it's own way with it's own set of commands.

You'll first need the list of GPIB instructions available for the scope (in the user or programmers manual), then you'll know what it's capable of.

Generally, any GPIB scope will allow you to set up all the usual stuff (timebase, trigger, vertical etc), and transfer the sampled data too. I'd be very surprised if you couldn't transfer the sampled data.

The extra connectors are probably for some other feature, parallel printer port, serial printer/plotter, or external digital word trigger maybe? I greatly doubt they have anything to do with transfering captured data, that is what GPIB is designed for.

GPIB "spy" software can come in handy if you have to play with the GPIB commands yourself instead of using the application that came with the scope (if any).

I have an OS4000 which I still use frequently - It's pretty straight forward, but I've never seen the manuals for it - any chance I could get the PDFs from you?
