test bench scripts

these are scripts for the gear on my test bench:

• owon xdm1241 multimeter uses a usb serial port connection for scpi
• owon dge2070 arbitrary waveform generator uses usbtmc connection for scpi

how to use

first, set up a virtual python environment within the test-bench directory:

python -m venv ./python

then install the following packages within the environment:

./python/bin/pip install pyvisa
./python/bin/pip install pyvisa-py
./python/bin/pip install pyusb
./python/bin/pip install python-usbtmc
./python/bin/pip install psutil
./python/bin/pip install zeroconf

then run ./discover-devices.py in order to find the connection strings used for your specific devices, you can then add your devices to the connections.py file to enable the scripts to find them.
