Chapter 23 Burst Modes 22-1
22. BURST MODES
Burst Mode uses a separate Burst Rate clock to initiate conversions. For the Pci55xx Series the Burst Rate
is defined as the time between ADC conversions and the duration of the burst is defined Burst Length.
When burst mode is enabled, each burst will be started by any of the three previously mentioned clock
sources, essentially the Clocking Source becomes the trigger of each Burst.
22.1 AL_SetBurstMode
Prototype C\C++
ERRNUM AL_SetBurstMode(LHLD lhld, LPSTR lpstrMode);
Visual Basic for Windows
Function AL_SetBurstMode(ByVal lhld As Long, ByVal lpstrMode As String) As Long
LHLD lhld handle of the LDSD
LPSTR lpstrMode address of the Burst mode string
The AL_SetBurstMode function sets the hardware Burst operation mode of the LDSD.
Parameter Description
lhld Identifies the instance of the logical device subsystem.
lpstrMode
Points to the desired Burst mode string. The available string settings are device
independent and are verified by ADLIB against the available Burst mode
options specified in the device's capabilities file.
Returns:
On success ERRNUM is set to 1, otherwise ERRNUM contains the last error code that occurred during the
call.
