6.8 _9812_Set_Clk_Src
@ Description
This function is used to specify the ADC clock source.
@ Syntax
C/C++ (DOS)
int _9812_Set_Clk_Src (int card_number, int clk_src, int ftpci)
C/C++ (Windows 95)
int W_9812_Set_Clk_Src (int card_number, int clk_src, int
ftpci)
Visual Basic (Windows 95)
W_9812_Set_Clk_Src (ByVal card_number As Long, ByVal
clk_src As Long, ByVal ftpci As Long) As Long
@ Argument
card_number: The card number of PCI-9812/10 to be
selected
clk_src: The ADC clock source, the valid values are
as follows:
0: INT_CLK: internal clock
1: SIN_CLK: external sin wave clock
2: SQR_CLK: external square clock
ftpci: Frequency selection.
AD2_GT_PCI: The frequency of A/D clock source is
higher than PCI clock frequency.
AD2_LT_PCI: The frequency of A/D clock source is lower
than PCI clock frequency.
