daqAdcGetFreq
DLL Function daqAdcGetFreq(DaqHandleT handle, PFLOAT freq);
C daqAdcGetFreq(DaqHandleT handle, PFLOAT freq);
Visual BASIC VBdaqAdcGetFreq&(ByVal handle&, freq!)
Delphi daqAdcGetFreq(handle:DaqHandleT; var freq:single)
Parameters
handle Handle to the device for which to get the current frequency setting
freq A variable to hold the currently defined sampling frequency in Hz
Valid values:
100000.0 - 0.0002
Returns DerrNoError - No errors (also, refer to API Error Codes on page 11-39)
See Also daqAdcSetFreq, daqAdcSetClock
Program References None
Used With All devices
daqAdcGetFreq reads the sampling frequency of the pacer clock.
Note: daqAdcSetFreq assumes that the 1 MHz/10 MHz jumper is set to the default position of 1
MHz.
daqAdcGetScan
DLL Function daqAdcGetScan(DaqHandleT handle, PDWORD channels, DaqAdcGain *gains, PDWORD
flags, PDWORD chanCount);
C daqAdcGetScan(DaqHandleT handle, PDWORD channels, DaqAdcGain *gains, PDWORD
flags, PDWORD chanCount);
Visual BASIC VBdaqAdcGetScan&(ByVal handle&, channels&(), gains&(), flags&(), chanCount&)
Delphi daqAdcGetScan( handle:DaqHandleT; channels:PDWORD; gains:DaqAdcGainP;
flags:PDWORD; chanCount:PDWORD )
Parameters
handle Handle to the device for which to get the current scan configuration.
channels An array to hold up to 512 channel numbers or 0 if the channel information is not desired.
*gains An array to hold up to 512 gain values or 0 if the channel gain information is not desired
flags Channel configuration flags in the in the form of a bit mask
chanCount A variable to hold the number of values returned in the chans and gains arrays
Returns DerrNoError - No error (also, refer to API Error Codes on page 11-39)

Used With All devices
daqAdcGetScan reads the current scan group consisting of all channels currently configured. The
returned parameter settings directly correspond to those set using the daqAdcSetScan function. For
further description of these parameters, refer to daqAdcSetScan. See ADC Flags Definition
table for channel flag definitions.
