How can I send a continious digital signal with a variable frequency between 0 and 10Fhz

[jean-claude]

Hello,

Using a PCI 6024, I try to generate a square signal with a variable frequency between 0 and 10 000 Hz  with signal Express, and send it to a digital output.

How can I do that please.

Hello.

The 6024 DAQ card doesn't have any correlated Digital I/O, that will allow you to generate some samples at a defined frequency, clocked with a hardware signal.

So the only thing you can do to have a variable frequency is to generate one sample (0 or 1) each time and to control the speed of your iterations by software.

Unfortunateley, you can't change dynamically your iteration's frequency with Signal Express, so you can't change dynamically your frequency with a 6024 and Signal Express.

Regards.
