Using software, you specify the range, gain, and analog input channel.

  • Page 63: Input Triggers

    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 the buffers on the queue have been filled or when you stop the operation. Note that when you stop the operation, the module completes the reading of the channel list.

Through software, specify the range for the entire analog output subsystem (0 to 2.44 V for the DT9812-2.5 V module or 10 V for the DT9812-10V, DT9812-10V-OEM, DT9812A, DT9813-10V, DT9813A, DT9814-10V, and DT9814A modules), and specify a gain of 1 for each channel.

  • Page 67: Single-Value Operations

    Principles of Operation Single-Value Operations Single-value operations are the simplest to use but offer the least flexibility and efficiency. Use software to specify the analog output channel, and the value to output from the analog output channel. Since a single-value operation is not clocked, you cannot specify a clock source, trigger source, or buffer.

  • Page 68: Data Transfer

    Chapter 5 Data Transfer If you are using continuous output mode, you specify whether to allocate and fill a single buffer (WrapSingleBuffer is True) or multiple buffers (WrapSingleBuffer is False). If you are using multiple buffers, data is written from multiple output buffers continuously; when no more buffers of data are available, the continuous output operation stops.

  • Page 73: Counter/Timer Operation Modes

    Principles of Operation Counter/Timer Operation Modes The modules support the following counter/timer operation modes: • Event counting • Frequency measurement • Edge-to-edge measurement • Rate generation Event Counting Use event counting mode if you want to count the number of falling edges that occur on Counter 0 In when the gate is active (high-level gate or software gate).

  • Page 74: Edge-To-Edge Measurement

    Chapter 5 Edge-to-Edge Measurement Use edge-to-edge measurement mode if you want to measure the time interval between a specified start edge and a specified stop edge. The start edge can occur on the rising edge or the falling edge of the Counter 0 Gate signal, and the stop edge can occur on the rising edge or the falling edge of the Counter 0 Gate signal.
  • Page 75 Principles of Operation To specify rate generation mode, use software to specify the counter/timer mode as rate, the C/T clock source as either internal or external, the clock divider (2 to 65536), and the active gate type (high-level or software gate).
