Interfaces for Data Acquisition
| The oscilloscope is really the go-to piece of laboratory equipment for many electrical measurements. A ’scope shows you voltages as a function of time. (It can also plot one voltage against another, which is sometimes handy.) See the Oscilloscopes page for more detailed information. |
| Pasco ScienceWorkshop 750 — Connects to a Macintosh or Windows computer via a USB port. Can acquire data at up to 250 kHz. This is the primary data acquisition platform for the mechanical oscillation experiments that involve carts. |
| Vernier LabQuest Mini — 100-kHz data acquisition platform. We have one of these, along with a rotary motion sensor, an ultrasonic position sensor, an accelerometer, and a force sensor. |
| LabJack — 50 kHz multifunction input and output. Very simple to program in Python. |
Sensors
| Rotary motion sensors — useful both for rotational and translational motion |
| Motion sensors — they use ultrasound to achieve about 1-mm resolution |
| Force Sensors — can measure forces up to 50 N |
| Accelerometers — can detect the accelerations of a shaking building |
