# Frequency Response Analyzer

This instrument measures the transfer function of a system by generating a swept sine wave and measuring the system response on the input

If you are directly using the RESTful API (e.g. using cURL), the instrument name as used in the URL is fra.

Functions

Multi-instrument: Frequency Response Analyzer in multi-instrument context
disable_output: Turn off the output sweep
fra_measurement: Sets up commonly used configurations in the Frequency Response Analyzer, including the frequency range, averaging, and swept sine amplitude.
get_data: Get current sweep data
getters: Frequency Response Analyzer - getter functions
load_settings: Load a previously saved `.mokuconf` settings file into the instrument. To create a `.mokuconf` file, either use `save_settings` or the desktop app.
measurement_mode: Toggle measurement between Input, Input/Output and Input/Input1
save_settings: Save instrument settings to a file. The file name should have a `.mokuconf` extension to be compatible with other tools.
set_defaults: Set the Frequency Response Analyzer to default state.
set_frontend: Configures the input impedance, coupling, and range for each input channel.
set_harmonic_multiplier: set the harmonic multiplier to demodulate at integer harmonic of output
set_output: Configures the output sweep amplitude and offset.
set_output_load: Configures the output load on a given channel.
set_output_phase: Configures the output phase for given channel.
set_output_termination: Configures the output termination on a given channel.
set_sweep: Set the output sweep parameters
start_sweep: Start sweeping
stop_sweep: Stop sweeping
summary: Returns a short summary of current instrument state
