#Setting up a new Repository
Pronounced "skippy". Module for instrument communication via SCPI, implemented using pyvisa and pyserial (depending on the device)
Features
- Communicate with devices over GPIB, RS232, or USB via SCPI protocol
- Several common instruments (Agilent 33210A, Keithley 2400 sourcemeter) already have dedicated classes
- Create new instruments with the SCPIDevice class
Getting Started
Installation
This package can be installed directly with pip from pypi:
pip install scippy
Agilent Example
The following example sets the frequency, amplitude, and output state of an Agilent 33210A instrument, and verifies that the parameters match the ones you set.
from scippy import Agilent
agilent = Agilent()
agilent.frequency = 2500
agilent.amplitude = 0.5
agilent.output_on = True
agilent.verify()
Keithley Example
The following sets up a Keithley 2400 source meter, sets the voltage compliance, and sets a current
from scippy import Keithley, ureg
keithley = Keithley()
keithley.current = 0.05 # Units assumed to be in Amps
keithley.voltage_compliance = 25 * ureg.mV # Set compliance to 25mV
voltage, current = keithley.measure() # Sets the output on, measures the current and voltage
print(voltage)
print(current)
Common Issues (Keithley)
Some instruments, unfortunately, have much less reliable communication interfaces than others. In particular, the Keithley is extremely sensitive to not being closed.
