Use the Scaling VIs to convert the clock and sample rate for the Loop Timer Express VI and to reconfigure input settings and post-process data from the FPGA Math & Analysis VIs.

Sample Rate To Loop Time
Converts the desired sample rate to the appropriate count for the Loop Timer Express VI and computes the achievable sample rate for use with other Scaling VIs.
Normalize Signal Generation Parameters
Converts frequency, phase, and duty cycle parameters into fixed-point units normalized to the clock rate. Use the Normalize Signal Generation Parameters VI in a host VI to convert values for the following FPGA VIs: Sine Wave Generator and Square Wave Generator.
Butterworth Coefficients
Generates filter coefficients for the Butterworth Filter Express VI. Use this VI in a host VI.
Notch Coefficients
Generates filter coefficients for the Notch Filter Express VI.
Scale Period
Converts the period output, expressed in samples, from the Analog Period Measurement Express VI to a period in units of seconds using the sample rate you specify. This VI also returns the frequency of the measurement in hertz using the sample rate you specify. Use the Scale Period VI in a host VI.
FFT to Spectrum
Converts the output of the Fast Fourier Transform (FFT) Express VI to a power or amplitude spectrum. The spectrum is single-sided and scaled.
Discrete FP Transfer Function to FXP
Converts a transfer function system model from floating-point to fixed-point representation. Obtain this model by entering values into the FP Transfer Function Model control or by using the VIs included with the LabVIEW Control Design & Simulation Module.
Convert PID Gains
Converts PID gains in the Academic, Parallel, or Series form to the normalized Parallel form that the PID VI expects.
