Syntax

P = freq2delta(F, W, B, D)

Description

freq2delta(F, W, B, D) converts a frequency value F in hertz into a uint32 delta phase value using the waveform size W, maximum buffer size of the PicoScope device B and DAC Frequency of the Arbitrary Waveform Generator (AWG), D.

Example

F = 1000;  % Hz
W = 16384; % samples
B = 32768; % samples
D = 20e6;  % 20 MS/s

P = freq2delta(F, W, B, D)

P =

  uint32

   107374

Input Arguments

F - the frequency in hertz (scalar or vector of 2 elements)
W - waveform size in samples (positive integer scalar)
B - maximum buffer size of the AWG in samples (positive integer scalar)
D - the DAC Frequency of the AWG in megasamples per second (real finite positive scalar value)
