    Chapter 6 Through software, specify the range as 0 to 10 V for unipolar signals or − 10 V to +10 V for bipolar signals. Note that the range applies to the entire analog input subsystem, not to a specific channel. DT3010 Series boards also provide gains 1, 2, 4, and 8, which are programmable per channel.

  • Page 110: Internal A/D Sample Clock

    Principles of Operation Note: If you enter digital I/O channel 32 in the channel list, the A/D sample clock (internal or external) also paces the acquisition of the 16 digital input lines. The following subsections describe the internal and external A/D sample clocks in more detail.

  • Page 111: Analog Input Conversion Modes

    Chapter 6 Note: The DT3010-268 board only provides an External A/D Trigger and Clock Enable signal. This signal is pulled high on the DT3010-268 board by a 22 kΩ resistor. You can use this signal to enable or disable the external digital trigger and the external A/D sample clock. A high signal enables both the external digital trigger and the external A/D sample clock, while a low signal disables both the external digital trigger and the external A/D sample clock.

  • Page 112: Triggered Scan Mode

    Principles of Operation To select continuously-paced scan mode, use software to specify the dataflow as Continuous, ContinuousPreTrigger, or Continuous PrePostTrigger; refer to page 115 for more information about these trigger acquisition modes. The initial trigger source depends on the trigger acquisition mode selected; refer to page 113 for more information on the supported trigger acquisition modes and trigger sources.

    Chapter 6 For example, if you are using 512 channels in the channel list, scanning the channel list 256 times every trigger or retrigger, and using an A/D sample clock with a frequency of 1 MHz, set the maximum retrigger frequency to 7.62 Hz, since 7.62 Hz = ( 512 * 256) +2 μs 1 MHz...

  • Page 114: Triggers

    Principles of Operation The conversion rate of each channel is determined by the frequency of the A/D sample clock; refer to page 108 for more information on the A/D sample clock. The conversion rate of each scan is determined by the period between external retriggers; therefore, it cannot be accurately controlled.

  • Page 115: External Digital (Ttl) Trigger

    Chapter 6 External Digital (TTL) Trigger For analog input operations, an external digital trigger event occurs when the DT3010 Series board detects either a rising or falling edge on the External A/D TTL Trigger input signal connected to screw terminal 77 on the DT740 screw terminal panel, screw terminal 49 on the STP268 screw terminal panel (attached to connector J1), or screw terminal 14 on the STP268-EC screw terminal panel.

  • Page 116: Trigger Acquisition Modes

    Principles of Operation Note: If you are using an analog threshold trigger to trigger both the A/D and the D/A subsystems, ensure that you use the same analog trigger type for both subsystems (either external or one of the analog input channels). The polarity of the triggers, however, can be different.

The multiscan count is 2 indicating that the channel list will be scanned twice per trigger or retrigger. In this example, post-trigger analog input data is acquired on each clock pulse of the A/D sample clock until the channel list has been scanned twice;...
  • Page 118 Principles of Operation If you are using software-retriggered scan mode and the post-trigger event has not occurred, the board continues to acquire pre-trigger data using the Triggered Scan Counter to clock the operation.

  • Page 128: Waveform Generation

    Principles of Operation Waveform Generation Use waveform generation mode if you want to output waveforms repetitively. Before this process can begin, the host computer must transfer the entire waveform pattern to output to the DACs from a single buffer allocated in computer memory into the output FIFO on the board.

  • Page 215 Appendix C Data acquisition boards can perform only as well as the input connections and signal integrity you provide. If you choose not to use the DT740, STP268, or STP268-EC screw terminal panel, considerations must be given as to how the signals interact in the real world as well as how they interact with each other.

  • Page 216: Analog Inputs

    Using Your Own Screw Terminal Panel Analog Inputs Typical data acquisition boards have three different types of analog input configurations that you can use: • Single-ended • Pseudo-differential • Differential Single-Ended Inputs With single-ended inputs, you have the maximum number of inputs but have the worst-case noise immunity without external signal conditioning.

  • Page 217: Differential Inputs

    Appendix C Differential Inputs Differential inputs offer the maximum noise rejection at the expense of half your total channel count. For the best results, shielded twisted pairs are a must. The shield must connect at one end so that ground currents do not travel over the shield. In low-level voltage applications, differential inputs reduce problems not only due to electrostatic and magnetic noise, but due to cross-talk and thermal errors.

  • Page 218: Analog Outputs

    Using Your Own Screw Terminal Panel Analog Outputs Most data acquisition boards have a minimum of two analog output channels, with a resolution of 12 to 16 bits (even though the accuracy may be less). On all Data Translation boards, we ensure that the analog outputs do not break into a high frequency oscillation with high capacitance loads that may be experienced with long cables.

  • Page 219: Digital Inputs And Counter/Timer Inputs

    Appendix C Digital Inputs and Counter/Timer Inputs TTL-type inputs must have current limiting so that circuitry is not damaged when power is removed. On all Data Translation PCI boards, current limiting is used to prevent damage in this fault condition. On high-speed clock inputs, a ground that is located in the connector next to the clock must be connected as a twisted pair with the high-speed clock input.

  • Page 220: Digital Outputs

    Using Your Own Screw Terminal Panel Digital Outputs If you are using the high drive capability of any of the PCI boards, ensure that the load is returned to the digital ground provided in the connector next to the outputs. If just eight of the digital outputs are switching 16 mA per output, then 128 mA of current flows.
