Description

The GP-LC-4X SIN block is used to specify a periodic sinusoidal signal to the GP-LC-4X DAC using output DMA.

Ports

Input

# Amplitude, V — signal amplitude
scalar

Details

Data types	`Float64`.
Complex numbers support	No

# Frequency, Hz — signal frequency

Complex numbers support	No

Parameters

All parameters listed above except the last three set the waveform only at initialisation. If at the first calculation step the corresponding parameters at the block inputs are different, the waveform will be changed.
