Connect to the Rigol DS1074Z in Python

Read our guide for turning Python scripts into Flojoy nodes.

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.

QCodes

Here is a Python script that uses Qcodes to connect to a Rigol DS1074Z Oscilloscope:

from qcodes.instrument.visa import VisaInstrument

class RigolDS1074Z(VisaInstrument):
    # ... code omitted for brevity ...

# Create an instance of the RigolDS1074Z instrument
rigol = RigolDS1074Z("rigol", "USB0::0x1AB1::0x04CE::DS1ZA222222222::INSTR")

# Connect to the instrument
rigol.connect()

# Access and set parameters
rigol.trigger_mode("edge")
rigol.trigger_level(0.5)

# Access channel parameters
channel1 = rigol.channels.ch1
channel1.vertical_scale(0.1)

# Get the trace data from channel 1
trace_data = channel1.trace()

# Disconnect from the instrument
rigol.disconnect()

This script creates an instance of the RigolDS1074Z instrument, sets the trigger mode and level, accesses the parameters of channel 1, retrieves the trace data from channel 1, and finally disconnects from the instrument.
