Principles of Operation Analog Input Features This section describes the following analog input (A/D) features of the DT9816 Series modules: • Input resolution, described below • Analog input channels, described below • Input ranges and gains, described on page 60 •...
Chapter 5 Specifying One or More Analog Input Channels You can read data from one or more analog input channels using an analog input channel list and continuous scan mode. Using software, specify the channels you want to sample. You can enter up to six entries in the channel list for this module.
Principles of Operation Note: According to sampling theory (Nyquist Theorem), specify a frequency that is at least twice as fast as the input’s highest frequency component. For example, to accurately sample a 2 kHz signal, specify a sampling frequency of at least 4 kHz. Doing so avoids an error condition called aliasing, in which high frequency input components erroneously appear as lower frequencies after sampling.
Chapter 5 Single-Value Operations Single-value operations are the simplest to use. Using software, you specify the range, gain, and analog input channel. The module acquires the data from the specified channel and returns the data immediately. For a single-value operation, you cannot specify a clock source, trigger source, scan mode, or buffer.
Principles of Operation Input Triggers A trigger is an event that occurs based on a specified set of conditions. Acquisition starts when the module detects the initial trigger event and stops when either no more buffers are available or you stop the operation. DT9816 Series modules support the following trigger sources: •...
Chapter 5 Digital I/O Features This section describes the following digital I/O features of the DT9816 Series modules: • Digital I/O lines • Resolution • Operation modes Digital I/O Lines DT9816 Series modules provide 8 digital input and 8 digital output lines. Using software, you can specify the digital I/O line that you want to read or write in a single-value digital I/O operation.
Principles of Operation Counter/Timer Features This section describes the following counter/timer (C/T) features of the DT9816 Series modules: • C/T channel, described below • C/T clock sources, described on page 66 • Gate types, described on page 66 • Pulse types and duty cycles, described on page 66 •...
Chapter 5 C/T Clock Sources The following clock sources are available for the counter/timer: • Internal clock – Through software, specify the clock source as internal, and specify the frequency at which to pace the counter/timer operation. The frequency of the internal C/T clock can range from 60 Hz to 6 MHz.
Principles of Operation Total Pulse Period high pulse low pulse Active Pulse Width Figure 19: Example of a Pulse Output SIgnal with a 50% Duty Cycle (High-to-Low Going) Counter/Timer Operation Modes DT9816 Series modules support the following counter/timer operation modes: •...
Chapter 5 Make sure that the signals are wired appropriately. Refer to page 42 for an example of connecting a frequency measurement application. Rate Generation Use rate generation mode to generate a continuous pulse output signal from Counter 0 Out; this mode is sometimes referred to as continuous pulse output or pulse train output.
