E4407B GPIB Screen Capture

A simple python script/example to save a screenshot from the E4407B spectrum analyzer via GPIB. It was written because it was the only spectrum analzyer I had access to at the time. This model has no USB interface, and the floppy drive was broken, so I had no interface to save data other than GPIB.
