Was hanging with the brother-in-law today and wanted to treat him to dinner, but the restaurant (http://www.mr-wok.com) was very busy so they pushed us back an addtional half hour when I called. What to do... what to do?

Go to Fry's!

Stopped in and was looking at the oscilloscopes and wishing as usual then looked over and saw 2 lonely scopes on the bottom shelf at the employee workstation and that made me curious. They were long discontinued, had no paperwork, and no accessories other than the front covers and power cords and they said the magic words "make us an offer".

They said an obcenely cheap price but one didn't boot so I said I'd take a gamble of Tektronix doing a warranty repair on one that I thought they stopped selling a while ago if they'd come down $200.

I walked out with a TDS3012B and a TDS3032B scope for a bit less than $1000 for the pair.

WOOHOO!
 
Well after that I suppose the brother-in-law had to spring for dinner?

Nope! We were playing host.

Sorry for the crappy iPhone pic...

They were display models so someone stole some of the knobs. I'm checking on pricing for replacement knobs.

Nice pickup! Tektronix is right off 190 near Independence, so you just need find the right person over there to hook you up. :)
 
I haven't tried the serial cables yet, but the export of data to floppy works fine :D

It exports as .isf or .csv and to use the .isf you need to run a conversion utility (free from Tektronix's website) that converts it to .csv. It's easier to save as .csv from the scope but the files are much bigger so it's faster just to do .isf and convert them.

The data is then put into Excel and put into a graph that is then copied over to Word. Here's a 1KHz square wave:

Once I cable up the PC to the scope I can do the captures straight from MS Word and may be able to skip some of the data conversion with Excel. I'm still playing and learning though.

This will be slick for writing instructions, documentation, and more. :D

Hmmm... the OpenChoice software from Tektronix allows input of the .isf file and will plot it along with some data about the file. It won't save to a .jpg but will let you copy to clipboard then you can paste it into MS Paint.

I think I like using Excel and plotting it better, but this looks more like a scope screen. Decisions, decisions.

I am to retarded to understand this thread.

It's just a picture of a waveform... a signal in a circuit.

Here's a video I found on YouTube of a sine, square, and triangle audio signal. The square wave (the middle sound) is 1KHz in this video and is a great representation of what the signal I grabbed from my oscilloscope is.

 
Can't it just take a screenshot to floppy or USB? Here is a screenshot from my Tek. You can also have it save them inverted with a white background. Have you checked for a firmware update?

I'm still working on figuring it out and haven't found that part yet.

If you look closely, you can see the tiny bits of static in this video match the shape of the wave on the screen when the tones are played, especially on the triangle wave.

Sweet!

Thanks man! Now to figure out the inversion of the image. :D

Cool! Just crawl through the settings menu and you should be able to find it. Would expect it to be near the file type setting, but it has been too long since I had to mess with it to remember.
