Configuring Frequency Modulation
To configure Frequency Modulation programmatically, use the
IKtM9383.
IVI interface of the KtM9383 IVI driver. Your
Modulation.Analog.Frequency
configuration routine should typically perform the following functions:
Configure the Function Generator(s)
For a given path, configure the function generator to be used.
