PROTOCOLS > SCPI

📄 IDN

Query a device's identity through the universal *IDN? SCPI command.

📄 MEASURE VOLTAGE

Query an instrument's measured output voltage, such as a DMM or power supply.

📄 SCPI WRITE

Write a SCPI command to a connected bench-top instrument and return the result.

QCodes Community

To connect to a DMM6500 Multimeter using Qcodes Community, you can use the following Python script:

from qcodes.instrument.visa import VisaInstrument
from qcodes.instrument import InstrumentChannel
from qcodes.utils.validators import Numbers
from functools import partial
from .Keithley_2000_Scan import Keithley_2000_Scan_Channel


class Keithley_Sense(InstrumentChannel):
    # ... (code omitted for brevity)


class Keithley_6500(VisaInstrument):
    # ... (code omitted for brevity)


# Create an instance of the DMM6500 Multimeter
dmm = Keithley_6500(name='dmm', address='YOUR_DEVICE_ADDRESS')

# Print the measured resistance
print(dmm.resistance())

# Print the measured DC voltage
print(dmm.voltage_dc())

# Print the measured temperature
print(dmm.temperature())

Replace 'YOUR_DEVICE_ADDRESS' with the actual address of your DMM6500 Multimeter.
