daqAdcSetFreq
Also See: daqAdcGetFreq, daqAdcSetClockSource,
daqAdcSetRate
Format
daqAdcSetFreq(handle, freq)
Purpose
daqAdcSetFreq calculates and sets the frequency of the internal scan pacer clock of the device using the
frequency specified in Hz.
Parameter Summary
Parameter Type Description
handle DaqHandleT Handle to the device whose acquisition frequency is being set
freq FLOAT The sampling frequency in Hz
Parameter Values
handle: obtained from the daqOpen frequency
freq: valid values range from 0.2 mHz to 1.0 MHz, depending on the device
Returns
DerrNoError No error
Function Usage
This function follows closely that of the daqAdcSetRate function with the mode parameter set to
DarmFrequency
. Valid values for the freq parameter range from 0.2 mHz to 1.0 MHz, but are dependent
on the device being used--see the discussion of actual scan rates in the entry for daqAdcSetRate.
This function is here for reference only. It is recommended that the daqAdcSetRate
function be used instead.
Prototypes
