Flojoy

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.

PyMeasure

from pymeasure.adapters import VISAAdapter
from pymeasure.instruments import Agilent33500

# Create a VISA adapter for the instrument
adapter = VISAAdapter("GPIB::1")

# Connect to the instrument
instrument = Agilent33500(adapter)

# Set the output waveform shape to sine
instrument.shape = "SIN"

# Set the frequency to 1 kHz
instrument.frequency = 1e3

# Set the amplitude to 1 Vpp
instrument.amplitude = 1

# Enable the output
instrument.output = True

# Disconnect from the instrument
instrument.disconnect()

This script connects to the instrument using a VISA adapter and creates an instance of the Agilent33500 class. It then sets the output waveform shape to sine, frequency to 1 kHz, amplitude to 1 Vpp, and enables the output. Finally, it disconnects from the instrument.

Note: Make sure to replace "GPIB::1" with the appropriate address of your Keysight 33521A RF Signal Generator.
