3.5.18 UsbDrDaqSetSigGenArbitrary
PICO_STATUS UsbDrDaqSetSigGenArbitrary(
short handle,
long offsetVoltage,
unsigned long pkToPk,
short * arbitraryWaveform,
short arbitraryWaveformSize,
long updateRate
)
This function allows full control of the arbitrary waveform generator by allowing an
arbitrary waveform to be passed to the driver.
Arguments:
handle:
handle returned from UsbDrDaqOpenUnit or
UsbDrDaqOpenUnitProgress
offsetVoltage:
The offset voltage in microvolts. The offset voltage
must be in the range -1.5 V to 1.5 V.
pkToPk:
The peak-to-peak voltage in microvolts. The maximum
allowed is 3 V.
arbitraryWaveform:
A pointer to an array containing the
waveform. The waveform values must be in the range -1000 to 1000.
arbitraryWaveformSize:
The number of points in the waveform.
updateRate
: This is the rate at which the AWG steps through the
points in the waveform. This value must be in the range 1 to 2000000
points per second.
Returns:
PICO_OK
PICO_NOT_FOUND
PICO_NOT_RESPONDING
PICO_INVALID_PARAMETER
