Daq API Command Reference 4.6-31
daqTest
Also See: DaqOpen
Format
daqTest(handle, command, count, cmdAvailable, result)
Purpose
daqTest tests a device for specific functionality.
Parameter Summary
Parameter Type Description
handle DaqHandleT Handle to the device for which the test is to be performed
command DaqTestCommand Specifies the type of test to be run
count DWORD Optional parameter which specifies the length of the test
cmdAvailable PBOOL Pointer to a return boolean indicating the availability of the test for
the device
result PDWORD Pointer to the test result field
Parameter Values
handle: obtained from the DaqOpen function
command: see table below
count: valid values range from 1 to 4,294,967,295; however, large values will result in excessively long tests
cmdAvailable: pointer to a boolean value; values are either true (
≠ 0) or false ( = 0)
result: a pointer to a value ranging from 0 to 4,294,967,295
Parameter Type Definitions
command-(DaqTestCommand)
Definition Description
DtstBaseAddressValid Test to determine if communications at currently configured base address are valid.
DtstInterruptLevelValid Test to determine if conflicts exist at the currently configured IRQ.
DtstDmaChannelValid Test to determine if conflicts exist at the currently configured DMA channel.
This command definition verifies DMA via available Input and Output speed tests, i.e.,
DtstAdcFifoInputSpeed, DtstDacFifoOutputSpeed, DtstIOInputSpeed,
and DtstIOOutputSpeed .
DtstAdcFifoInputSpeed Test to determine max speed for analog data transfer to computer memory.
DtstDacFifoOutputSpeed Test to determine max speed for analog data transfer from computer memory.
DtstIOInputSpeed Test to determine max rate for digital data transfer to computer memory.
DtstIOOutputSpeed Test to determine max rate for digital data transfer from computer memory.
DtstFifoAddrDataBusValid WaveBook Only : WBK30 communication check (use DtstFifoMemCellValid instead)
DtstFifoMemCellValid WaveBook Only : MegaFIFO (WBK30) memory test.
DtstHardwareCompatibility WaveBook Only : Verifies the DSP Boot Code revision level. 1 = PASS, 0 = FAIL.
DtstFirmwareCompatibility WaveBook Only: Verifies the FPGA revision level. 1 = PASS, 0 = FAIL.
DtstExpansionCompatibility WaveBook Only: Verifies that the connected WBK modules are compatible with the main unit.
1 = PASS, 0 = FAIL.
DtstExpUpgradeCompatibility WaveBook Only: Verifies that the main unit Firmware is compatible with all connected WBK
modules. 1 = PASS, 0 = FAIL.
Returns
DerrNoError No Error
