Connect to the Series 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

import qcodes as qc
from qcodes.instrument_drivers.rohde_schwarz.ZNB import ZNB

# Connect to the Series Network Analyzer
znb = ZNB("znb", "TCPIP0::192.168.15.100::inst0::INSTR")

# Print the instrument ID
print(znb.get_idn())

# Turn on the RF output
znb.rf_power(True)

# Set the start and stop frequencies
znb.channels.ch1.start(1e9)
znb.channels.ch1.stop(10e9)

# Set the number of points in the frequency sweep
znb.channels.ch1.npts(1001)

# Perform a frequency sweep and get the magnitude and phase data
data = znb.channels.ch1.trace.get()

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

# Turn off the RF output
znb.rf_power(False)

# Close the connection to the instrument
znb.close()

Note: Replace "TCPIP0::192.168.15.100::inst0::INSTR" with the actual address of your Series Network Analyzer.
