Connecting to R&S ZNB20 by Rohdes&Schwarz in Python

Instrument Card

The R&S ZNB20 from R&S is a mid range vector network analyzer with two or four test ports for the frequency range from 100 kHz to 20 GHz. It has a dynamic range of 135 dB which makes it possible to perform precise measurements on wideband DUTs or components whose behavior at low frequencies is especially important. The analyzer has a large 12.1 inches touch screen interface which makes it easy to control and review test results. The ports on the R&S 20 have 2.92 mm Male connectors.

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 R&S ZNB20 Network Analyzer using Qcodes, you can use the following code:

from qcodes.instrument_drivers.rohde_schwarz.ZNB.ZNB import ZNB

# Create an instance of the ZNB20 Network Analyzer
znb = ZNB('znb', 'TCPIP0::192.168.1.1::inst0::INSTR')

# Connect to the instrument
znb.connect()

In the code above, we import the ZNB class from the qcodes.instrument_drivers.rohde_schwarz.ZNB.ZNB module. Then, we create an instance of the ZNB class with the desired name (znb) and the appropriate VISA resource string (TCPIP0::192.168.1.1::inst0::INSTR) for your specific instrument.

Finally, we call the connect() method to establish a connection to the instrument.

Note: Make sure to replace 'TCPIP0::192.168.1.1::inst0::INSTR' with the correct VISA resource string for your specific instrument.
