How to output continuous sin, square, triangle, pulse or any

waveform through a DAQ

Using USB 6008/9& USB 6211

DAQs

First: Using USB 6008/9 DAQs

Using USB 6008/9 DAQs

Unfortunately USB 6008/9 Can not generate continues waveforms but it can generate:

• A pulse with pulse width>500 msec through an analog output as shown in the next example

Second: Using USB 6211 DAQs

Using USB 6211 DAQBy USB 6211 DAQ you can generate:

1- Up to two continues (sin, triangle, pulse and square) waveforms through any of the two analog output channels. Using this DAQ you can generate a perfect continuous signal up to 30 kHz.

2- Extra two square waves (or pulses) through the counter output channels with frequency reaches 10 MHz.

Second METOD

Note • You can change the amplitude, phase and

the off set of the signal waveforms generated from the analog output channel.

• The square (or pulse) generate from the counter output channels (2 channels) its amplitude is fixed and between 0 and 5V. And you can not control the phase

output channels
