What's New in Capstone 2

Circuits Emulation

Reinforce circuit concepts and tackle student misconceptions using circuit visualization. Combine real-world circuits with simulations, animation, and live measurements.

With the Circuits Emulation tool in Capstone 2, you can:

  • Construct and modify circuits
  • Show conventional current and electron flow animation
  • Animate circuits with live sensor data

Drag components out from the components list. Rotate components, and connect pieces together by drawing wires.

Trials Table

This is how science is actually done.

You never take only one run in science. You take multiple runs, and calculate averages. Next, you vary a parameter while holdinb other constant; again, taking more runs and calculating averages. Most software data tables don’t actually allow this to be done easily.

The Capstone Trails table was created for how data is collected in the science lab, and allows for the kind of analysis students need to perform.

  • Organize your data to easily define physical relationships.
  • Track variables
  • Average runs
  • Plot derived values

Using the simple pendulum lab as an example, students will time a simple pendulum under various conditions. They will vary the mass, length, and starting angle. The Capstone Trials Table allows you to vary and keep track of experimental parameters between trials, and runs taken in each trial. You can also keep track of statistics for averaged runs and experimental error.

Blockly Coding

Helps students develop computational thinking skills

Physics educators want more experimental control and programming access to all PASCO interfaces and sensors. Students need tools to develop creative programming and problem-solving skills in science. Blockly coding has been built into Capstone 2, giving teachers and students the tools they need to develop these skills.

Graph Pop-Up Tools

Now, whenever tools are activated, the most common actions will be easily accessible on the graph. The pop-up tools allow for easy access to tool features and options.


PASCO Capstone allows users to quickly layout custom pages, automatically recognizes sensors when connected, has a powerful set of analysis tools and much, much more.

PASCO Capstone was built from the ground up to be the most powerful and flexible option for physics and engineering applications.

  • Windows/Mac compatibility
  • Can be used with all current and legacy PASCO USB interfaces.
  • Works with all PASCO sensors -- ScienceWorkshop, PASPORT, and Wireless.
  • Completely customizable lab pages
  • Multiple displays including graphs, tables, oscilloscope, bar meters, FFT and more
  • Deep video analysis tools
  • Opens DataStudio, Xplorer GLX and SPARKvue files.

The PASCO Advantage

Student Journal

As students complete their lab assignment, they can capture aspects of their lab into the student journal for later assessment in their lab writeups.

Modern User Interface (UI/UX)

Other software still relies heavily on dialog boxes whereas Capstone has incorporated more modern UI design elements such as in-context options and display tools. We are constantly improving our user experience to eliminate barriers to usage and improve student learning.

Customizable User Interface

Features can be turned on/off so when an assignment is opened, the student only has access to the necessary tools for the assignment.

Signal Generator

Capstone’s signal generator controls allow for advanced settings to accommodate the demands of advanced circuits labs.

  • Waveforms: DC, Sine, Square, Triangle, Positive/Negative Ramp, Positive Square, Positive Up/Down Ramp.
  • Sweep: Single, Repeat, Bi-directional
  • Voltage offset
  • Voltage and Current and Limit


Capstone provides a display that behaves like a digital oscilloscope with tools specific to how oscilloscopes are used (trigger, single trace collection, sample rate tied to time axis scale, set trace offset). This is very different from other software that uses the same graph display for slow and faster sampling rates.

Video Analysis Unique Features

  • Object vectors
  • Frame Skipping for analyzing high speed video
  • Magnifying glass for more accurate data placement

Graph Display Unique Features

  • Multiple area selection for data analysis
  • Exclude data points
  • Mutli-Y Coordinate tool
  • Axis Quick-calcs

What's New

Bar Meter

A bar meter has one or more bars that go up and down as the measurement value changes. In this example, eight temperature sensors are distributed along a metal bar and one end is immersed in boiling water and the other is immersed in ice water. The eight bar meters show the temperatures along the metal bar as it reaches a dynamic equilibrium.

Sync Multiple Wireless Sensors

With PASCO's new syncing technology, wireless sensors are automatically synced as soon as more than one is plugged in. If you desire to sync them more closely just before recording, you can click on the new sync button on the Sampling Control bar.

Open SPARKvue Files in PASCO Capstone

Collect data using a mobile device running SPARKvue Software and then open the SPARKvue file in Capstone for more extensive analysis.

Smart Fan Control

  • When the new Smart Fan Accessory is plugged into a Smart Cart, you can control the Smart Fan directly from Capstone.
  • Use the slider to set the thrust.
  • Set the fan to turn on and off based on a measurement (such as Smart Cart Position) or time.
  • Hands off: Start the fan remotely in the software.
  • Use a calculation to define the thrust: Thrust = 10*[Force] will make the thrust proportional to the force exerted on a force sensor.



Importing and Exporting


  • External data (as .csv files) can be imported into Capstone and analyzed
  • Text, images, and videos can also be easily brought into your Capstone workbook
