Interfacing Raspberry Pi with Keithley 3390

[John Manuel]

I wanted to interface Rpi with the function generator Keithley 3390. My goal is to capture the signal which Keithley 3390 generates and plot it using Rpi, i.e, to function it as an oscilloscope. I went through the reference manual of Keithley 3390 but could not come up with a solution. Please help. Any input would be very much welcome.

Please define "capture".
Do you want the Pi to look at the coax output of the Keithley and measure the voltage?
