CN-0269 Software User Guide

Overview

CN-0269 is a high performance industrial signal level multi-channel data acquisition circuit that can process 16-channels of single-ended inputs or 8-channels of differential inputs with up to 18-bit resolution.

A single channel can be sampled at up to 1.33 MSPS with 18-bit resolution. A channel-to-channel switching rate of 250 kHz between all input channels provides 16-bit performance.

The signal processing circuit combined with a simple 4-bit up-down binary counter provides a simple and cost effective way to realize channel-to-channel switching without an FPGA, CPLD or high speed processor. The counter can be programmed to count up or count down for sequentially sampling multiple channels, or can be loaded with a fixed binary word for sampling a single channel.


Required Equipment

  • EVAL-SDP-CB1Z Evaluation Board (SDP-B Board)
  • EVAL-CN0269-SDPZ Daughter Board (CN0269 Board)
  • EVAL-CFTL-6V-PWRZ Power Supply or equivalent +6V power supply
  • CN0269 SDP Evaluation Software
    • (supplied with provided CD in kit)
  • PC with the following Minimum Requirements
    • Windows XP Service Pack 2 (32-bit)
    • USB type A Port
    • Processor rated at 1GHz or faster
    • 512 MB RAM and 500 MB available hard disk space
  • USB type A to USB type mini-B cable
  • Signal Generator for Sin Wave with +/-10V Vpp and frequency upto 500KHz

General Setup

Installing the Software

  1. Extract the file CN0269 SDP Eval Software.zip and open the file setup.exe.

    NOTE: It is recommended that you install the CN0269 SDP Evaluation Software to the default directory path C:\Program Files\Analog Devices\CN0269\ and all National Instruments products to C:\Program Files\National Instruments\







  2. Click Next to view the installation review page.



  3. Click Next to start the installation.



  4. Upon completion of the installation of the CN0269 SDP Eval Software, the installer for the ADI SDP Drivers will execute.

    NOTE: It is recommended that you close all other applications before clicking “Next”. This will make it possible to update relevant system files without having to reboot your computer.




  5. Press “Next” to set the installation location for the SDP Drivers.

    It is recommended that you install the drivers to the default directory path
    C:\Program Files\Analog Devices\SDP\Drivers




  6. Press “Next” to install the SDP Drivers and complete the installation of all software. Click “Finish” when done.



Connecting the Hardware

  1. Connect J1 of the EVAL-CN0269-SDPZ (CN0269 Board) to CON A of the EVAL-SDP-CB1Z (SDP-B Board)
  2. Set the JP3 and JP4 on EVAL-CN0269-SDPZ (CN0269 Board) to select the input range and Connect the signal correctly according to the pin definition.



  3. Connect the USB Cable to the SDP-B Board and leave the other side of the cable unconnected.
  4. Connect the 6V DC power to CN2 and +/-12V DC power to CN1 and Turn on the DC power supply to power up the board.
  5. Connect the USB Cable to PC



Using the Evaluation Software

Software Control and Indicator Descriptions

Software Overview


  1. Connect Button
    • When this button is pressed, the SDP-B Board makes a USB connection to the CN0272 Board. A connection to the SDP-B Board must be made to use the software.
  2. Start Acquisition Button
    • When this button is pressed, the SDP-B Board starts to acquire data from EVAL-CN0269-SDPZ Board.
  3. Save Data Button
    • When this button is pressed, the SDP-B Board save the data into the same directory where the application is installed.

      NOTE: If the CN0269 SDP Evaluation Software is installed in the default directory, the data files could be found in C:\Program files\Analog Devices\CN0269\.







  4. Control Tabs
    • Configuration Tab: All the configuration items through EVAL-SDP-CB1Z Board to EVAL-CN0269-SDPZ board are organized on this tab. More details about Configuration Tab will be introduced in the following Section.
    • Multi-Channel Tab: This tab shows all the signals on one tab which is convenient to compare the signals from different channels. More details about Multi-Channel Tab will be introduced in the following Section.
    • Single Channel Tab: This tab shows the specific channel which is more clearer than Multi-Channel Tab. More details about Single Channel Tab will be introduced in the following Section.
    • SDP Information: The Firmware version of EVAL-SDP-CB1Z Board is shown on this tab. More details about SDP Information Tab will be introduced in the following Section.
