National Instruments PCI/PXI-6602 Armed Pulse Generation

PCI/PXI-6602 Armed Pulse Generation block

Library

Simulink® Real-Time™ Library for National Instruments®

Note

The inputs to the block are separate, one for the high count (H), one for the low count (L), and one for the arm input (A). If the arm input signal is less than 0.5, the frequency generation is disabled. If the arm input signal is greater than or equal to 0.5, the frequency generation is enabled.

Block Parameters

Channel

From the list, choose one of the following:

  • 1

  • 2

  • 3

  • 4

  • 5

  • 6

  • 7

  • 8

These parameters specify the counter to be used with this driver block. In each case, one block is required for each port.

The reference frequency for this board is 80 MHz.

Initial high count

Enter the number of clock ticks the counter should maintain for a high level.

Initial low count

Enter the number of clock ticks the counter should maintain at a low level.

Sample time

Enter the base sample time or a multiple of the base sample time (-1 means sample time is inherited).

PCI slot (-1:autosearch)

If only one board of this type is in the target computer, enter -1 to locate the board.

If two or more boards of this type are in the target computer, enter the bus number and the PCI slot number of the board associated with this driver block. Use the format [BusNumber,SlotNumber].

To determine the bus number and the PCI slot number, type:

tg = slrt;
getPCIInfo(tg, 'installed')
