PicoScope 3425 Differential PC Oscilloscope is a 4-channel, 12-bit resolution, 5 MHz bandwidth, 20 MS/s sampling rate, 400 V differential and common-mode range oscilloscope, including PC oscilloscope and spectrum analysis software PicoScope and PC data logger software PicoLog. It is powered by USB port and includes Application Programming Interface (API) and example code. This oscilloscope does not require expensive differential preamplifiers or probes, and is ideal for measuring low-level signals in physics and biology laboratories, and for capturing power waveforms from switch mode power supplies and motor inverters.
