The application also provides sample projects that can be customized to your needs so you don't have to begin building your system from scratch. It has analysis capabilities, UI displays for scientific and engineering data, and the ability to incorporate different programming approaches. LabVIEW uses a visual programming language, known as 'G,' to help users visually create their systems.

The software is available for Windows, OS X, and Linux. It is a complete develop environment geared towards scientists and engineers taking measurements. National Instruments LabVIEW is a platform used to build measurement and control systems. Integrates with a multitude of LabVIEW devices.Provides sample projects that can be customized to your needs.Uses a graphical programming language to help users create measurement and control systems.Output expression for the Transient Analysis. You will notice the expression now appears in the Selected variables for analysisВ list as shown in the next figure:ДЇigure 5. The Analysis ExpressionВ window will look as shown below: Return to the VariablesВ list and select the V(Input)В variable.Select theВ *В symbol from the FunctionsВ list and click on Copy function to expression.Select V(Output)В from the VariablesВ list and click on Copy variable to expression.The output voltage is represented by the variable V(Output)В and the voltage taken at the input is represented by the variable V(Input). The items in the Variables in circuitВ list display the voltage and current values which can be grouped into expressions. You can now add an expression to analysis.

Refer to the Transient Analysis tutorial for more details on how to configure theВ Analysis ParametersВ tab.

Configure the Analysis ParametersВ as shown in Figure 3.ДЇigure 3.В Analysis parameters for the Transient Analysis.

Select FileВ»Open Samples.В The Open fileВ window opens.

In this example you will add a custom expression to a Transient AnalysisВ to multiply the input by the output voltages. The amplifier is configured for maximum output power at 1.5MHz. In the following example you will perform the simple steps needed to create an expression while performing Transient Analysis on a RF Amplifier circuit.Д¬onsider the RF Amplifier circuit shown in Figure 2. In Multisim this is done easily through the analysis options. There are times, however, when you might want to take these variables and combine them into expressions, such as power, to evaluate important characteristics of the circuit. These can all be outputted to the Grapher ViewВ during the simulation and analysis process. For example, in the Transient AnalysisВ window shown in Figure 1, the OutputВ tab displays variables describing node voltages and branch currents in the circuit. The analysis tools in Multisim provide a sophisticated manner in which to study the characteristics of a circuit. In Multisim you have the ability to add expressions into analyses.

This tutorial is part of the SPICE Analysis Fundamentals Series.В Each tutorial in this series provides you with step-by-step instructions on how to configure and run the different SPICE analyses available in Multisim. With this window you merely need to specify the parameter values and output nodes of interest. This abstracts away the complexities associated with SPICE syntax and configuration of an analysis. Multisim simplifies the procedure for an advanced analysis by providing a configuration window. For each analysis you need to set settings that will inform Multisim exactly what to analyze, and how.

Each analysis helps you to obtain valuable information such as the effects of component tolerances and sensitivities. These analyses range from the basic to sophisticated. Multisim features a comprehensive suite of SPICE analyses for examining circuit behavior.
