PASPORT 1 MHz 2-Channel Voltage Sensor - PS-2190


Shown in use with an RLC circuit board.


The 1 MHz 2-channel Voltage Sensor is a high speed, two channel PASPORT voltage sensor that has a basic voltage range of ±10 volts. It has amplifiers that allow full-scale input ranges of ±1 volt and ±0.1 volt. The sensor uses an oversampling scheme that allows input sampling at speeds up to one million samples per second.

The 1 MHz 2-channel Voltage Sensor connects to an interface. Measurements are then recorded and displayed using PASCO Software.

Note:   When using the PS-2190 with SPARKvue the maximum sampling rate is limited to 1 kHz
