  • Page 19: Analog Output Channels

    Analog Output Channels DDA-08 boards contain two quad DACs (quad DAC0 and quad DAC1), which provide eight analog output channels. DDA-16 boards contain four quad DACs (quad DAC0, quad DAC1, quad DAC2, and quad DAC3), which provide 16 analog output channels. Quad DAC0 contains channels 0 through 3;...

  • Page 20: Output Ranges

    In multi-channel list mode, the DDA-08/16 writes all data to a random list of analog channels. The channel-gain list may contain channels in any order but only with unity gain. In simultaneous mode, the list may not repeat the same channel.
  • Page 21 All channels on a quad DAC have the same voltage output Notes: range; you cannot select a voltage output range on a channel-by-channel basis. Make sure that you select a voltage output range that includes all the output values required by the device connected to your board. In addition, make sure that the range does not exceed the required values excessively;...

  • Page 22: Clocks

    Pacer Clocks The pacer clock determines the update rate (the time between each update of all the channels on the quad DACs in the update group). DDA-08/16 boards provide the following software-selectable pacer clocks: Hardware internal pacer clock — The internal pacer clock uses an onboard time base.

  • Page 24: Output Clock

    Also keep in mind the settling time of the channels on the DDA-08/16 board; refer to Appendix A for information. At power-up, the pacer clock is disabled.
  • Page 25 (no delay). The DDA-08/16 can write analog output samples after the hardware detects a digital trigger condition. Use post-triggering in DriverLINX when you want to synchronize the start of data acquisition with an external signal.

  • Page 26: Pulse Length

    Pulse Length The period of the output pulse is equal to the prescaler value. Since the prescaler generates a square wave, the length of the output pulse is equal to half of the prescaler value. For example, if the prescaler value is 10 ms, the length of the output pulse is 5ms.

  • Page 27: Hardware Trigger

    In DriverLINX, Timing Events specify how the hardware paces or clocks the sample output. DriverLINX uses the Timing Event to program when the DDA-08/16 writes the next analog output sample to the DACs. The DDA-08/16 supports the following Timing Events: None —...

  • Page 28: Figure 2-4. Using A Hardware Trigger

    External pacer clock — When the trigger event occurs, the board begins monitoring the state of the external pacer clock signal. At the next active edge of the external pacer clock, the channels are updated. Figure 2-4 illustrates how the channels are updated when using a rising-edge hardware trigger.

  • Page 29: Hardware Gate

    Hardware Gate You can enable a hardware gate through software. A hardware gate is an externally applied, level-sensitive, digital signal that determines when the analog output channels on the quad DACs in the update group are updated. You connect the gate signal to the GATE IN pin (pin 21) of the main I/O connector.

  • Page 30: Figure 2-5. Using A Hardware Gate

    In DriverLINX, use an internally clocked rate generator when Note: you want to write analog output samples at equally spaced time intervals. The DDA-08/16 hardware can write the selected analog output channels simultaneously at each timing event, or individually, with one channel per timing event.

  • Page 31: Interrupts

    Interrupts You can enable DDA-08/16 boards to automatically generate an interrupt each time the analog output channels on the quad DACs in the update group are updated. To enable interrupts, you specify an interrupt level (3, 5, 7, 10, 11, or 15) through software. On power-up, interrupts are disabled.
