Does NIDAQ 6009 support clocked operation?

[xiaoran94]

Hi,

I am using NIDAQ 6009 to output two analogue voltage. code followed:

"s = daq.createSession('ni');

addAnalogOutputChannel(s,'Dev1','ao0','Voltage');

addAnalogOutputChannel(s,'Dev1','ao1','Voltage');

outputSignal1 =  linspace(-0,1)';

outputSignal2 = linspace(-1,1)';

plot(outputSignal1);

hold on;

plot(outputSignal2,'-g');

xlabel('Time');

ylabel('Voltage');

legend('Analog Output 0', 'Analog Output 1');

queueOutputData(s,[outputSignal1 outputSignal2]);

s.startForeground;

"

but there is an error:' queueOutputData is disabled because the session contains channels that do not support clocked operations.‘

What should I do?

Regards

Xiaoran

AO on NI USB-6009 is static. You cannot use clocked operations.

Thank you very much! How about NIDAQ-6212?

I checked the specifications of these devices. It seems that no words indicates that it supports clocked operations or not.

The USB-6212 supports clocked analog output. However, if you want a low cost device, you may want to take a look at the USB-6003. It supports clocked analog input / output like the 6212, but slower. Is is still faster than the 6009.

None of these devices support clocked digital i/o. If you think you will ever need that you will need something like a USB-6341, which is not USB powered and is quite larger.
