Virtual Instruments
Bring in-class instruction to life
Multisim is the only software of its kind to provide a suite of virtual instruments, 9 in total. Introduce students to the world of electronic instrumentation with unbreakable virtual instruments that look and operate just like their real-world counterparts. Best of all, the need for expensive hardware is reduced, students learn without risk to their safety, and access to virtual instruments is extended to all students in the computer lab. Begin by creating a circuit. Next, connect an instrument to the circuit in exactly the same way you would with real test equipment, make adjustments to the controls (SPICE commands are sent transparently to the simulation engine) and the appropriate signals are displayed on the face of the instrument. With Multisim's virtual instruments, SPICE quirks and peculiarities are hidden from view. Students can, therefore, tap into the full power of SPICE without having to focus on messy code and syntax.
 
Post Processor
Simulation results can be plotted to a fully customizable grapher, then mathematically manipulated using a wide range of functions (arithmetic, trigonometric, calculus, algebraic, boolean logic). Graphs can be easily copied to student assignments or placed on a schematic to illustrate a signal. Alternatively, use the powerful ability of OLE (included in Multisim) to export your data to math applications (eg. Mathcad) or spreadsheets applications (eg. Microsoft Excel) for further investigation and analysis.
 
VIRTUAL INSTRUMENTS
 
 
  • Oscilloscope
     Time base adjustable from nanoseconds to seconds with internal or external triggering.
  • Function Generator
     Produces square, triangular, or sinusoidal waves. Adjustable frequency, duty cycle, amplitude, and DC offset.
  • Multimeter
     Measures AC and DC current, voltage, resistance and decibel loss.
  • Bode Plotter
     Measures frequency response of a circuit. Plots both gain or phase shift against frequency.
  • Network Analyzer
     Measures the S-parameters of networks, with Smith Charts and impedance matching.
  • Word Generator
     Drives digital logic one word at a time, bursting through user-defined sets of data, or cycling continuously
  • Logic Analyzer
     Triggered internally or externally by recognition of a pre-set defined bit pattern.
  • Spectrum Analyzer
     Measures amplitude versus frequency with adjustable span and amplitude range.
  • Distortion Analyzer
    Provides distortion measurements for signals. Measures both intermodulation distortion and total harmonic distortion.
  • Wattmeter
     Performs power readings at any point in the circuit.
 
 
Multisim's virtual oscilloscope works just
like a real oscilloscope on your bench.
