NI CLAD Exam Objectives :

Section Weight Objectives
Hardware 10% • Connecting Hardware:  Sensors, DAQ, Devices under test (DUT.
• Acquiring and validating a signal
• Processing signals
• Using appropriate sample rates
LabVIEW Programming Environment 25% • Setting up and using a LabVIEW Project to:
    o Add, delete, and move elements
    o Use libraries and appropriate types of folders
    o Avoid cross-linking
• Data Types:
    o Recognize data types on the front panel
    o Recognize data types on the block diagram from terminals and wires
    o Choose appropriate controls, indicators, data types, & functions for a given scenario
• Predicting order-of-execution and behavior of  
    o A non-looping VI
    o A Simple State Machine
    o An Event-driven UI Handler
    o Parallel Loops (without queues)
• Using basic functions to create a simple Acquire-Analyze-Visualize application
• Troubleshooting by identifying and correcting the cause of a broken arrow or incorrect data
• Error handling using error clusters and merge error functions to ensure errors are handled well
• Navigating LabVIEW help to get more information about inputs, outputs, and functions
LabVIEW Programming Fundamentals 50% • Loops
    o Create continuous HW acquisition or generation loop by applying a Open-Configure-Perform Operation-Close model.
    o Retain data in shift registers
    o Use input and output terminals effectively, including:
? Determining the last value output
? Indexing input and output terminals
? Concatenating output
? Using conditional output
? Using shift registers, both initialized and uninitialized.   
    o Use timing of loops appropriately, including:
? Software timing
? Hardware timing
    o Use For Loops and While Loops appropriately
• Arrays
    o View data from an n-channel HW acquisition VI (using the DAQmx Read VI) using a waveform graph, waveform chart, or numeric/waveform array indicator.
    o Extract a single channel of data (waveform or 1D Array) from a:
? 1D waveform array representing acquired data from multiple channels
? 2D numeric array representing acquired data from multiple channels
? 1D numeric array representing single measurement from multiple channels
    o Use a For Loop with auto-indexing and conditional tunnels to:   
? Iterate through an array  
? Iterate processing code on each channel of data in a 1D waveform array   
? Generate an array of data that meets required conditions   
    o Identify by sight and be able to use and predict the behavior of the following array functions and VIs:   
? Array Size
? Index Array
? Replace Subset
? Insert Into Array
? Delete From Array
? Initialize Array
? Build Array
? Array Subset
? Max & Min
? Sort 1D Array
? Search 1D Array
? Split 1D Array
• Writing conditional code to perform an action based on the value of a user input or a measurement result.   
• Reading and Writing data to a file
    o Use Open/Act/Close model for file I/O
    o Write data to a text file using high-level file I/O functions
    o Continuously stream data to a text file or a TDMS file
    o Append data to an existing data file
    o Log data using simple VIs
    o Acquire data from DAQmx functions
    o Display data on a graph  
    o Save data to a CSV file   
    o Choose single measurement/multiple channel and single channel/multiple measurements configurations appropriately  
Programming Best Practices 15% • SubVIs – Reusing Code
    o Create SubVIs to increase readability and scalability of VIs   
    o Configure the subVI connector pane using best practices
    o Choose appropriate code as a SubVI source  
• Clusters – Grouping Data of Mixed Data Types
    o Create, manipulate, analyze, and use cluster data in common scenarios
    o Group related data by creating a cluster to improve data organization and VI readability
• Type Defs – Propagate Data Type Changes
    o Create Type Defs and use Type Defs in multiple places
    o Update Type Defs to propagate changes to all instances of the Type Def
