Connecting to LDA-302P-H by Vaunix in Python

Instrument Card

The LDA-302P-H Lab Brick USB programmable 50 Ohm digital attenuator has an input power of up to +33 dBm, and offers frequency coverage of 10 to 3,000 MHz. It has an attenuation range of 31.5 dB and a step size of 0.5 dB. The unit is powered and controlled by USB connection to a PC or self-powered hub, and is programmable for fixed attenuation or swept attenuation ramps directly from the included graphical user interface (GUI) software.

Connect to the LDA-302P-H in Python

PROTOCOLS > SCPI

To connect to a LDA-302P-H 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-302P-H Digital Attenuator
lda = LDA('lda', serial_number=302, dll_path='path/to/dll')


# 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()

Make sure to replace 'path/to/dll' with the actual path to the DLL file for the LDA-302P-H Digital Attenuator.
