Oscilloscope and MAX
I just found an oscilloscope on the street yesterday!
There is an IEEE-488 port on the rear end on the thing. I’ve read that one could use that to send the info from the oscilloscope into a computer and:
I was thinking about getting a cable like this to send the info from the osc to my computer:
So the question is, do you guys have any idea or even experience with what you could do to route the signals from the oscilloscope into Max/MSP?
My idea was to send some sort of signal into the osc to get some sort of waveform and then “modulate” the wave on the osc and get MAX to measure how the wave looks on the display and make some changes on rulers and knobs based on the data received from the osc.
Hope you guys can help!

lucky you, this sort of gear is pretty pricey if you need it…

I’d try to get hold of a manual. You might find it online…

Check out first what protocol its using. I guess it will be simply

The manual will be your friend…

Oscilloscopes don’t alter the signal, they measure it…

I am not quite sure this port can be used for input on the Osc point of view. It is used most of the time to send data/graphs to a printer to have a “hard copy” of your measure. But usualy not to control the Osc.
And I don’t really get where you going with this idea…
But the best option is to try to find the Osc Manual indeed.
Anyway, if it is recognize as a USB device by your computer (with the cable you showed) you should be able to use the hi object to get the data. Then you need to built a parser in Max depending on the protocol used by the Osc.
Stefan is right, you were lucky to find one of these. Even if it is quite an old model now, it is still very useful and pricy !

Hey thanks for the replies! I will go look for some sort of manual. I haven’t got the osc here with me right now so unfortunately, I can’t see what brand and type it is. (It’s at a friends place right now – a heavy fucker! not the kind of type you carry with you in the bus)
And yeah, I guess I was quite lucky to find it. I could tell I’ve found something valueable from a long distance when I saw it. Next to it was some old pc-monitors, a lot of printboards with cables I couldn’t tell what was for and many types of electronic gizmos with knobs and stuff. I’ll take a picture of everything I gathered next week when I’ve brought it all home to my own place.
But I thought that maybe one could use the print data that was sent into the computer. Like “if that knob is turned up, the curve is increasing, so increase this ruler/knob ind MAX/MSP as well”
