  • Page 13: Overview

    Overview The DAS-4300 Series consists of the DAS-4301/8K board. The ® DAS-4301/8K is an 8-bit data acquisition board available for IBM ® PC AT or compatible computers, with a conversion rate of up to 1 Gsamples/s. This chapter describes the features of the DAS-4301/8K board, the software that supports it, and available accessories.

    Functional Description This chapter describes the features of the DAS-4301/8K board from a functional point of view. The intent of these descriptions is to familiarize you with the operating options and to enable you to make the best use of your board.

  • Page 18: Channels

    Channels The DAS-4301/8K board can acquire data from one of two analog input channels at a time: Channel A, accessed from the Ch A connector, or Channel B, accessed from the Trg/Ch B connector. You use software to specify Channel A. To specify Channel B, leave a jumper installed in positions 1 and 2 of jumper block J103 (the factory-default configuration), and use software to select Channel B.

The scope and test program supports binary, twos complement, and absolute value data coding of the digitized analog input values. The DAS-4300 Series Function Call Driver and VTX use twos complement data coding only. Memory This section describes memory on the DAS-4301/8K board and on the host computer.
  • Page 20: Host Computer Memory

    Host Computer Memory DAS-4301/8K boards require part of both the host computer I/O address space and the host computer memory address space. I/O Address Space The DAS-4301/8K board uses a block of 16 bytes (ports) in the I/O address space of the host computer to set up the board’s parameters. These ports can be located anywhere below 400h, provided that they are not used by your host computer.

  • Page 22: Bus Interface

    Bus Interface The ISA bus interface provides 16-bit data transfers and allows the host computer to initialize all onboard parameters, read from and write to onboard memory, and trigger the board. As mentioned in the previous section, the bus interface uses two distinct address spaces of the host computer: a 16 byte consecutive segment in the I/O address space for control information and a 16K byte segment in the memory address space for data exchange.

  • Page 27: Trigger Acquisition

    Trigger Acquisition Depending on your application, you can sample data before and/or after a trigger event occurs. If you want to collect data after a specific trigger event, use post-trigger acquisition. If you want to collect data before or before and after a specific trigger event, use about-trigger acquisition. The maximum number of samples you can collect for each trigger event is 8,192.
  • Page 28: About-Trigger Acquisition

    Once the board is armed, the next valid trigger event starts the acquisition. When the trigger event occurs, the post-trigger length, which includes the post-trigger delay and the number of samples to acquire (defined by the buffer length), is decremented until it reaches zero, at which point acquisition stops.
  • Page 29: Equivalent Time Sampling (Ets)

    (where the number of post-trigger samples is zero) and about-trigger acquisition (where you specify the number of post-trigger samples); refer to the DAS-4300 Series Function Call Driver User’s Guide for information. The DAS-4300 scope and test program uses the term pre-trigger mode for both pre-trigger acquisition and about-trigger acquisition.

  • Page 33: Random Interleave Sampling (Ris)

    Random Interleave Sampling (RIS) In addition to ETS, the DAS-4301/8K board provides Random Interleave Sampling (RIS). Like ETS, RIS allows the DAS-4301/8K board to sample a repetitive signal at rates above 1 Gsamples/s. Unlike ETS, however, the signal does not have to be coherent with the pacer clock. This feature is particularly convenient in scope-type applications where you may not be overly concerned about the time it takes to complete the acquisition but you want to watch the screen filling with data.

  • Page 48: Setting The Memory Address

    Setting the Memory Address The onboard 8K byte memory on the DAS-4301/8K board is mapped into a 16K byte window in upper memory (above 640K bytes). The DAS-4301/8K board is shipped with a memory address of CC00:0000. If your application requires a different setting, use jumper block J401 to set the memory address, as shown in Table 3-3.
  • Page 49: Setting The Interrupt

    The host computer must leave room for the onboard memory of the DAS-4301/8K board in its memory address map. To ensure that the host computer is configured to leave room in its memory address map, you must exclude the memory area of 16K bytes (CC00:0000 to CFFF:000F or your memory address setting) from the memory available for the EMS manager of your system (for example, QEMM or EMM386).
