Connecting to LDA-802-16 by Vaunix in Python

Instrument Card

The LDA-802-16 Digital Attenuator is a rack mounted 16-channel high dynamic range, bidirectional, 50 Ohm step attenuator. The LDA-802-16 provides 120 dB of attenuation control range from 200 to 8000 MHz with a step size of 0.1 dB. The attenuators are easily programmable for fixed attenuation, swept attenuation ramps and user defined fading profiles directly from the included Graphical User Interface (GUI). Alternatively, for users wishing to develop their own interface, Vaunix supplies LabVIEW drivers, Windows API DLL files, Linux drivers, Python examples and much more.

📄 SCPI WRITE

Write a SCPI command to a connected bench-top instrument and return the result.

QCodes Community

To connect to a LDA-802-16 Digital Attenuator using Qcodes Community, you can use the following Python script:

from qcodes import Station
from qcodes_contrib_drivers.drivers.Vaunix_LDA import LDA

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

# Connect to the LDA-802-16 Digital Attenuator
lda = LDA('lda', serial_number=80216)

# Add the LDA to the station
station.add_component(lda)

# Print the IDN of the LDA
print(lda.get_idn())

# Set the attenuation to 10 dB on channel 1
lda.ch1.attenuation(10)

# Close the connection to the LDA
lda.close()

This script creates a Station object to hold the instruments. It then connects to the LDA-802-16 Digital Attenuator using the LDA driver from the qcodes_contrib_drivers package. The LDA is added to the station and its IDN is printed. The attenuation on channel 1 is set to 10 dB, and finally, the connection to the LDA is closed.
