Analog Output Waveforms
This chapter covers many topics associated with generating analog output waveforms, including
how to condition signals by adding components to the open component locations of the
SCB-68A for lowpass filtering and attenuating voltage applications.
Caution
Add components at your own risk. NI is
not
liable for any damage
resulting from improperly added components.
In addition to the applications described in this chapter, you can build many other types of signal
conditioning using the component pads and the general-purpose breadboard area of the
SCB-68A. Refer to the
Soldering and Desoldering Components on the SCB-68A
section of
Chapter 1,
Getting Started with the SCB-68A
, for more information about adding components
and for soldering and desoldering instructions.
After building one of the applications described in this chapter or your custom circuitry, refer to
the
section of Chapter 1,
Getting Started with the SCB-68A
, for
instructions about how to configure the SCB-68A in Measurement & Automation Explorer
(MAX). You can create virtual channels in MAX to create a custom scale or map your voltage
ranges to the type of transducer that you use.
Analog Output Channel Pad Configuration
When you use the SCB-68A with a 68-pin or 100-pin MIO DAQ device, you can use the
component pads on the SCB-68A to condition two AO channels. Figure 3-1 shows the circuitry
for both analog output channels on the SCB-68A.
