agilent-rs232

A basic script to read the waveform from an Agilent 54621A (Note: Has also been checked with 54622D) oscilloscope via RS232 and display it using matplotlib.

I wrote a blog post to go along with this! You can find it here!

Usage

The program is written in python3.

usage: agilent-rs232.py [-h] [--port PORT] [--baud BAUD] [--channel CHANNEL]
                        [--length LENGTH]

optional arguments:
  -h, --help            show this help message and exit
  --port PORT, -p PORT  set serial port (default /dev/ttyUSB0)
  --baud BAUD, -b BAUD  set serial baud rate (default 57600)
  --channel CHANNEL, -c CHANNEL
                        set probe channel (default 1)
  --length LENGTH, -l LENGTH
                        number of samples (default 1000)

Other implementations

I'm not the first person to want to solve this problem! Although I did not use their code, a more full-featured approach to reading scopes and other tools from Python can be found under the PyVisa library.
