How to read this table? If you have activated all eight channels and are using the board in standard mode (not FIFO) and your external clock is known to be around 15 MHz you have to set the EXRANGE_BURST_L for the external range.

Example:


SpcSetParam (hDrv, SPC_CHENABLE,		CHANNEL0		CHANNEL1 CHANNEL2 CHANNEL3); //		activate	4 channels
SpcSetParam	(hDrv, SPC_EXTERNALCLOCK,		1);		//	activate	external clock
SpcSetParam	(hDrv, SPC_EXTERNRANGE, EXRANGE_BURST_M);				// set external range to Burst M

External clock with divider

The extra clock divider can be used to divide an external fed in clock by a fixed value. The external clock must be > 1 MS/s. This divided clock is used as a sample clock for the board.

Register	Value	Direction	Description
SPC_CLOCKDIV	20040	r/w	Extra clock divider for external samplerate. Allowed values are listed below

Available divider values

1	2	4	8	10	16	20	40	50	80	100	200
400	500	800	1000	2000
