Frequency Response

Description: Creates a plot of the frequency response of a system by sweeping a frequency generator and taking the power at the input frequencies.

Model/BOF/configuration script examples: link

Terminal Command: frequency_response.py spec_config

Parameters Table:

Key	Value Data	Value Description	Example
test_source	Dictionary	Information of the source (generator) for the test	Same as for ADC5G calibration
chnl_step	Integer	Frequency step in number of channels used to compute the transfer function	10
datadir	String	Folder name where to save the results (is created if doesn't exist)	'transfer_function'
pause_time	Float	Time in seconds to wait between frequency changes. Use longer waits for slow changing sources	0.1

The frequency response script also needs a spec_info parameter from the spectrometer script in order to get the spectral data. It uses the first bram list of spec_info and ignore the others if they exist.
