View Oscilloscope Images over Serial Connection


Is there a program that will take images from an oscilloscope that I have connected via serial port?

A quick Google search turns up some that may work:

http://sourceforge.net/projects/gscope

http://xoscope.sourceforge.net/

Without knowing the make/model of the oscope it is difficult to provide any specific help.
As suggested by TBOne there are several linux applications available but they may not be suitable with your hardware.

I uses several Tektronix oscopes that can output data to the serial port. I configure them to print a BMP or JPG picture. I then configure the computer to capture data (i.e. minicom) to a file then all I need to do is push the print button. Of course you need to setup the the computer and the oscoope for the same serial port settings.

Once you get the basic communications working, most/many/some scopes will allow you to acquire data from them by querying appropriately. You can acquire the data in real time (although serial is too slow to do this well; consider GPIB if possible), and use any of a number of plotting tools to plot the raw data, or roll your own if you're handy with graphics programming.
If you are talking about transferring bitmap image files from the scope, it will probably involve the use of some standard file-transfer protocol, and this should be documented with the scope. If you can provide specific make/model information about the scope, someone may be able to point you to a specific solution.

It looks like the xoscope software has what I'm looking for. I use the PL-2303 usb-to-serial adapter and it appears that xoscope is able to access the /dev/ttyUSB0 device. I'm unable to connect it to an oscope until class on Monday so I'll hook it up and see what happens. If I'm successful I'll be sure to give you a thumbs up
