The most powerful educational lab interface in the world.
The 850 is PASCO’s most flexible interface and is designed specifically to be used in conjunction with the powerful PASCO Capstone software.
The 850 interface boasts four digital inputs, four analog ports, four PASPORT sensor ports, a 15 W function generator, dual high speed function generators and much more. For a limited time, it also includes a PASPORT High Current Sensor.
The Four Digital Inputs allow direct use of photogates and other digital sensors (such as Time-of-Flight), with no adapter needed! The four analog inputs can be used with PASCO’s entire line of analog CI sensors. Plug voltage sensors into them and measure voltages to ±20 V at sample rates of up to 10 MHz on 1 or 2 channels or 1 MHz on four channels.
The four PASPORT sensor ports accept any of the more than 70 available PASPORT sensors. And ScienceWorkshop and PASPORT sensors can be used together meaning that there are over 120 sensors to choose from to meet any application.
The outputs on the 850 include a 15 Watt Function generator which supplies up to ±15 V @ 1 A, DC and AC. Both the output voltage and current are measured directly by the 850 and can be recorded as data.
Waveforms include sine, triangle, square and ramp (all with DC offset), with a frequency range of 0.001 Hz to 100 kHz. The two additional Function Generators supply low power at higher frequencies (up to 500 kHz), with independent control of frequency, waveform, amplitude and phase shift.
