Performs statistical calculations on a signal. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application signal The input signal. This input supports the following data ...

In some situations, you might know that you want to repeat an operation, but you do not know exactly how many times you want to repeat that operation. Instead, you know only that the operation should repeat ...

A loop is a programming element that executes the same code multiple times, or iterations. Types of Loops Loop Behavior Example Diagram For Loop Repeats the code inside the loop for a set number of iterations. ...

Parsing a string into smaller pieces allows you to perform operations on individual words or groups of characters in the string. These words or groups of characters are often referred to as tokens. A token ...

Generates a signal containing a sine wave. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application Algorithm for Simulating a Sine Wave If sequence Y represents a sine ...

Generates a signal containing a square wave. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application Algorithm for Simulating a Square Wave If sequence Y represents ...

Factors like inefficient memory use, poorly designed panels, and too many I/O calls can negatively affect the execution speed of your VI. However, there are several strategies you can use to ensure that ...

Group data elements of the same type. An example of a simple array is a 1D text array that lists the eight planets of our solar system in order. Array elements are ordered. An array uses an index so you ...

By default, each call to the subVI is executed one after another. This may cause your application to execute slowly or have unexpected behavior. To allow multiple calls to a subVI to execute simultaneously, ...

Chart numeric data by displaying a history of values. How is Charting Different Than Plotting? Graphs and charts differ in the way they display and update data. VIs with a graph usually collect the data ...

Chart and plot data. What Is the Difference between Graphs and Charts? You can collect data, usually in an array, and then plot the data to a graph. This process is similar to a spreadsheet that first ...

Returns the absolute value of the input. DAQExpress does not support FPGA devices Supported in VIs that run in a web application x An input to this operation. This input supports waveforms and any data ...

Returns the sum of all of the elements in a numeric array. DAQExpress does not support FPGA devices Supported in VIs that run in a web application numeric array An array of any number of dimensions. This ...

Computes the sum of the inputs. You cannot add two timestamp values together. DAQExpress does not support FPGA devices Supported in VIs that run in a web application input An input to this operation. This ...

Computes the logical AND of the inputs. If all inputs are True, this node returns True. Otherwise, it returns False. This node performs bitwise operations on numeric inputs. DAQExpress does not support ...

Returns the maximum and minimum values found in an array, along with the indexes for each value. DAQExpress does not support FPGA devices Supported in VIs that run in a web application array An n-dimensional ...

Converts an array of strings into a relative or absolute path. If you have an empty string in the array, the directory location before the empty string is deleted in the path output. This behavior is the ...

Plot 3D data on a 2D plot by using color to display the values of the third dimension. For example, you can use an intensity graph to display patterned data, such as terrain, where the magnitude represents ...

Group and organize controls and indicators. When Should I Use a Tab Control? Tab controls are useful when you have several panel objects that are used together or during a specific phase of operation. ...

Converts a 1D array to a cluster of elements of the same type as the array elements. The maximum cluster size for this node is 256. To change the number of elements in the converted cluster, click Array ...

Converts an array of any dimension to a delimited string that mimics a spreadsheet with rows, columns, and pages. DAQExpress does not support FPGA devices Supported in VIs that run in a web application ...

Returns the value 6.022140857e23. The Avogadro constant is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole. DAQExpress does ...

Converts a Boolean array to an integer by interpreting the array as the binary representation of the number. If the number is signed, this node interprets the array as the two's complement representation ...

Represents a True or False value on the diagram. DAQExpress does not support FPGA devices Supported in VIs that run in a web application

Converts a Boolean False or True value to a 16-bit integer with a value of 0 or 1, respectively. DAQExpress does not support FPGA devices Supported in VIs that run in a web application boolean A scalar, ...
