Generate a 10V 10 kHz square signal

[fourmi]

I would like to generate 5 square signals 0-10V 0-10kHz with a PCI-6704 and a PCI-6602. Is it possible and what are the connections I have to do between these two devices ?
Same question for 1 square signal 0-10V 0-10kHz with a PCI6040E ?
Thanks in advance

Forumi,

You can generate the 5 square waves from 0 to 10V with the PCI-6704, without any problem. However,if you want to generate those same 5 square waves with the PCI-6602, you will be able to do that, but you will need external circuitry, because the pci-6602 outputs only TTL compatible signals; thus, there must be amplification of those signals in order to reach the desired 10 V. However, the update rate can be reached easily. Furthermore, if you want to synchronize both boards, that's not possible, because the pci-6704 does not have a RTSI bus, which allows it to get synchronized with the rest of the boards.

Finally, the latter board is an E Series one, and you can only output up to 2 analog signals out of it. You can accomplish the desired specifi
cations,but not the number of output signals.

Regarding connections, you can check the User Manual for each board. I add the links below:

If you have further questions, please be more specific next time. Thanks!

Hello;

You can't do such task with the 6602, since that board input/output only TTL type of digital pulses, which are 0-5V only.

Regarding the 6704, that board provides only static output signals, meaning that the update of the analog output channels will be done through Software calls only. Since you need a fairly fast update rate, Windows won't be able to handle that speed.

You can do that with the 6040E, since that board has an analog output update rate of 1MHz.
You don't need to do any connection when generating the analog output waveform. Actually, either Labview or NI-DAQ has examples showing how to do that.

Hope this helps.
