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 ZVL 13 Network Analyzer using Qcodes Community, you can use the following Python script:

from qcodes import Station
from qcodes.instrument_drivers.rohde_schwarz.ZVL13 import ZVL13

# Create a station to hold the instruments
station = Station()

# Connect to the ZVL 13 Network Analyzer
zvl13 = ZVL13('zvl13', 'TCPIP0::192.168.1.1::inst0::INSTR')
station.add_component(zvl13)

# Print the available parameters and functions of the ZVL 13
print(zvl13.parameters)
print(zvl13.functions)

# Set the start frequency, stop frequency, and number of points
zvl13.start(1e6)
zvl13.stop(1e9)
zvl13.npts(101)

# Perform a frequency sweep and get the magnitude and phase data
mag, phase = zvl13.trace_mag_phase()

# Print the magnitude and phase data
print(mag)
print(phase)

# Disconnect from the instruments
zvl13.close()

Note: Replace 'TCPIP0::192.168.1.1::inst0::INSTR' with the actual address of your ZVL 13 Network Analyzer.
