DAPL Output Configuration Commands
Output configuration commands define signal generation with clocked output updates. The output sequences are characterized by the number and sequence of channels, timing, output periods, and hardware triggering.
Output configuration commands are bracketed by special group delimiter command lines.
- Begin a group of commands that define an output updating configuration.
- End an output updating configuration definition.
Configuration commands appear between the
- Declare the number of output channels to be defined in the configuration.
- Establish the destination port for an output signal, associating it with a logical data channel.
- Set the time interval between consecutive updating operations.
- Set the number of updates to send before automatically terminating output updating.
- Specify the number of terms for a repeating output waveform.
- Specify the amount of buffered data to collect before proceeding with hardware-clocked updates.
- Select a hardware trigger control mode.
- Select a hardware sample clocking mode.
- Select continuous or burst updating mode.
- Selecta synchronization option for a multi-board system.
Subject to irregular time delays from task scheduling, some special processing commands can bypass the output clocking and send updates directly to output ports.
- Bypass output clocking and send data directly to a digital-to-analog converter port.
- Bypass output clocking and send data directly to a digital port.
