nirfsg

Python control of NI RF Signal Generators using NI-RFSG

Installation

> pip install nirfsg

Or, after cloning repo:

> pip install .

Documentation

Currently supported models:

• PXIe-5654

> from nirfsg import PXIe_5654
> sig_gen = PXIe_5654(<resource>)
> sig_gen.rf_frequency = 2e6 # Hz
> sig_gen.rf_power = 0 # dBm
> sig_gen.initiate()
...
> sig_gen.close()

As a context manager:

> with PXIe_5654(<resource>) as sig_gen:
    sig_gen.rf_frequency = 20e9 # Hz
    sig_gen.rf_power = 13 # dBm
    sig_gen.initiate()
    # do some measurements

Context manager will close the session at exit, which will stop generation.
