What is NI SignalExpress?

SignalExpress National Instruments SignalExpress is interactive software designed to meet the needs of design and test engineers who need to quickly acquire and analyze electronic signals. SignalExpress simplifies your exploratory and automated measurement tasks by offering:

  • A drag-and-drop, nonprogramming environment
  • Rapid measurement configuration
  • Integration of simulation data
  • Extended functionality through NI LabVIEW

What's New in SignalExpress 1.1?

New Hardware Support

Nonprogramming Environment

SignalExpress introduces an innovative approach to configuring your measurements using intuitive drag-and-drop steps that do not require developing code. Unlike traditional benchtop measurement tools, SignalExpress combines the optimal balance of measurement functionality and ease of use to assist you in streamlining a variety of applications:

  • Design modeling
  • Design verification
  • Design characterization
  • Device validation
  • Automated test troubleshooting

Rapid Measurement Configuration

There are many built-in steps available for immediate use in SignalExpress. You can instantly focus on the signal measurements and analysis you need by using steps from the following categories:

  • Signal I/O - Generation and acquisition of signals from a variety of hardware devices
  • Processing - Functions such as signal alignment, filtering, and averaging
  • Time Domain - Analysis such as amplitude measurement, timing, and histograms
  • Frequency Domain - Measurements for power, frequency response, tone, and distortion
  • Test Operations - Sweep and limit tests for measurement automation

Integration of Simulation Results

SignalExpress also contains steps to integrate simulation data into your measurement environment. With these steps, you can import simulation data from popular electronic design software tools such as OrCAD SPICE, PSpice, and Multisim from Electronics Workbench. You can use this powerful feature to quickly compare measured data against simulation data.

Extended Functionality through LabVIEW

If you ever need a specific measurement, analysis, or comparison step that is not built in to SignalExpress, you can use LabVIEW to create user-defined steps that you can insert into SignalExpress projects. You also can convert SignalExpress projects into LabVIEW block diagrams to maximize code reuse throughout the product-development cycle.
