Chapter 3 Analog Output

When you use an analog trigger source, the samples are paused when the Analog Comparison

Event signal is at a high or low level, depending on the trigger properties. The analog trigger

circuit must be configured by a simultaneously running analog input task.

Note Depending on the C Series I/O module capabilities, you may need

two modules to utilize analog triggering.

Minimizing Glitches on the Output Signal

When you use a DAC to generate a waveform, you may observe glitches on the output signal.

These glitches are normal; when a DAC switches from one voltage to another, it produces

glitches due to released charges. The largest glitches occur when the most significant bit of the

DAC code changes. You can build a lowpass deglitching filter to remove some of these glitches,

depending on the frequency and nature of the output signal. Go to

ni.com/support for more

information about minimizing glitches.

Getting Started with AO Applications in Software

You can use the cDAQ chassis in the following analog output applications:

• Single-point (on-demand) generation

• Finite generation

• Continuous generation

• Waveform generation

For more information about programming analog output applications and triggers in software,

refer the LabVIEW Help or to the NI-DAQmx Help.
