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.
The PicoScope 3425 Differential PC Oscilloscope is a four‑channel, USB‑powered instrument offering 12‑bit vertical resolution and up to 5 MHz analogue bandwidth. It supports differential voltage measurements up to 400 V and includes software for scope and spectrum analysis as well as data logging.
The datasheet lists detailed performance figures such as sampling rates, input impedance, common‑mode range, and environmental operating limits. It also outlines the accessories supplied in the kit, including screened BNC leads, current‑clamp adapters, test probes, crocodile clips, and a USB cable.
