Increase Frequency of Pulse Generation

[thescar]

Hi all,
i'm using a NI PCI 6229 to generate by its counter  a trigger for a strobo lamp..
actually i'm using the Gen DIG Pulse TRAIN continuos.vi that could reach freq till a maximum of 100 HZ

SInce the lamp could work at higher Freqs, i would like to know how to increase the freq in that vi.

TIA,

Thescar.

Hi thescar,

Ar you sure it only works till 100Hz???????????????????? It will work much faster... How are you measuring it? probably it is a problem with the way you are observing those readings.

Anyway you can generate pulses by 3 ways:

1. Introducing frequency

2. Introducing period

3. Introducing ticks

The 3rd way you can select the numer of ticks the pulse is at low level and the number to high level. You also need to say which is the source for the ticks and here you can select (also anothers but i recommend you chose one of these) the 1Khz timebase, the 100Khz timebase and the 20Mhz timebase.

So, for example if you select as source 1Khz timebase and 2 ticks at low level and 2 at high level you will be obtaining a pulse of 1Khz/4=250Hz. With all those possible configurations you will be able to set very different frecuencies over 100 Hz.
