Example Python script to implement the Frequency Response Analyzer (basic)

#
# Moku example: Basic Frequency Response Analyzer
#
# This example demonstrates how you can generate output sweeps using the
# Frequency Response Analyzer instrument, and view one frame of the transfer
# function data.

from moku.instruments import FrequencyResponseAnalyzer

# Launch FRA and connect to your device via IP

                averaging_time=1e-3, averaging_cycles=5, settling_cycles=5,

    # beware if your range includes low frequencies!
