National Instruments PCI-6023E Pulse Generation

PCI-6023E Pulse Generation


Simulink® Real-Time™ Library for National Instruments®


The inputs to the block should be a two-element vector. The first element is the number of counts (of the 20 MHz source clock) that the counter should maintain at a low level, and the second element is the number of clock ticks for a high level. For example, to generate a pulse train at 1 kHz with 25% low and 75% high, use the vector

[5000 15000]

Block Parameters


From the list, choose Counter 0, Counter 1, or Both to select the counter(s) to be used with this driver block. In each case, one block is required for each physical board.

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')
