+ | {{ : | ||
+ | -**LDAC COntrol** | ||
+ | * Always check the box before starting any test | ||
+ | -**Write to DAC Button** | ||
+ | * Enter the digital input code in “DIN” | ||
+ | * When “WRITE TO DAC” button is clicked, the digital input code is sent to the DAC | ||
+ | -**Output Indicator** | ||
+ | * The LED string indicates the digital input code being written to the DAC (from bit 15 to bit 0) | ||
+ | -**System Status String / LED Indicator** | ||
+ | * The string indicator displays a message to the user detailing the current state of the software | ||
+ | * The LED indicator displays the current state of the software in the form of an LED. There are three status LED colors\\ {{: | ||
+ | -**Code Step Control** | ||
+ | * Enter the code step between each digital input to be written to the DAC | ||
+ | -**Agilent 3458A GPIB Address Control** | ||
+ | * Enter in the GPIB address of the multimeter | ||
+ | * GPIB Address can be determined from the multimeter by manually pressing down on SHIFT+Local. | ||
+ | -**Current Code / Voltage Indicator** | ||
+ | * This indicates the current digital input code and output voltage of the DAC | ||
+ | -**File Directory Control** | ||
+ | * This allows you to enter the file directory and name to save the INL/DNL measurement data | ||
+ | -**INL / DNL measurement graphs** | ||
+ | * These graphs display the INL and DNL vs. input digital code when data collection is done\\ \\ {{ : | ||
+ | -**Transfer Function Graph** | ||
+ | * This graph shows the transfer function of the DAC output voltage vs. input digital code\\ \\ {{ : | ||
+ | -**SDP Board Firmware Information** | ||
+ | * This gives you the up to date information on the SDP board firmware | ||

+ | ==== Connecting the Hardware and Taking Measurements ==== | ||
+ | |||
+ | - Connect the SDP Board to the CN0348 Board | ||
+ | - Connect +6V and analog ground to the CN0348 board (J1) | ||
+ | - Connect the USB cable supplied with the SDP board to the USB port on the PC and the SDP board | ||
+ | - Connect Vout (J3) to a multimeter | ||
+ | - Open **CN0348.exe**. | ||
+ | - The application will attempt to connect to the board immediately | ||
+ | - Check **LDAC** box | ||
+ | - Perform functionality test by entering the following in **DIN** and click **WRITE TO DAC** | ||
+ | - 0000; multimeter should read close to 0V | ||
+ | - FFFF; multimeter should read close to 5V | ||
+ | - **OUTPUT** (Bit 15 to Bit 0) should also light up the associated LED indicator | ||
+ | |||
+ | For INL/DNL data collection: | ||
+ | - Connect Vout to the Agilent 3458A multimeter | ||
+ | - Connect the Agilent 3458A to the PC using a GPIB to USB Type A connector (for data collection via Labview software) | ||
+ | - Set the multimeter to have “NPLC” as 1 | ||
+ | - Enter GPIB Address of Agilent 3458A. | ||
+ | - Enter desired **Code Step** | ||
+ | - Code Step = 16 takes about 4min 10sec to finish measurement | ||
+ | - Code Step = 32 takes about 2min 5sec to finish measurement | ||
+ | - Enter the file name and path you want to save data in **Enter file name to save data before running** | ||
+ | - Click on **Start** | ||
+ | - **Current Code** and **Current voltage** should show the progress of measurements | ||
+ | - To exit, go to File > Exit. | ||
