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

To connect to a Keysight E8267C RF Signal Generator using Qcodes, you can use the following Python script:

from qcodes.instrument.visa import VisaInstrument

# Create a class for the Keysight E8267C RF Signal Generator
class KeysightE8267C(VisaInstrument):
    def __init__(self, name, address, **kwargs):
        super().__init__(name, address, terminator="\n", **kwargs)
        # Add parameters and commands specific to the Keysight E8267C
        self.add_parameter(
            name="frequency",
            label="Frequency",
            unit="Hz",
            get_cmd="FREQ?",
            set_cmd="FREQ {}",
            get_parser=float,
            vals=Numbers(min_value=100e3, max_value=40e9),
        )
        # Add other parameters and commands as needed

# Create an instance of the Keysight E8267C RF Signal Generator
signal_generator = KeysightE8267C("signal_generator", "TCPIP0::192.168.1.1::INSTR")

# Connect to the signal generator
signal_generator.connect()

# Use the parameters and commands of the signal generator
frequency = signal_generator.frequency()
print(f"Current frequency: {frequency} Hz")

# Disconnect from the signal generator
signal_generator.disconnect()

This script creates a custom class KeysightE8267C that inherits from VisaInstrument provided by Qcodes. It adds parameters and commands specific to the Keysight E8267C RF Signal Generator, such as frequency. The script then creates an instance of the KeysightE8267C class, connects to the signal generator, retrieves the current frequency, and finally disconnects from the signal generator.
