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.
