The PicoScope 4000 Series PC Oscilloscopes are extremely versatile, with an oscilloscope and spectrum analyser included in every model. These scopes support 12-bit resolution, 80MS/s real-time sampling rate, USB 2.0 interface for data and power, 32M sample buffer size, and up to 4 channels.
The 4000 Series combines a high‑resolution oscilloscope and a spectrum analyser in a single USB‑powered instrument. It offers 12‑bit ADC resolution, up to 80 MS/s real‑time sampling, a 32 M sample buffer, and up to four input channels with BNC connectors.
Key specifications include a 20 MHz bandwidth (10 MHz on the 50 mV range), 10 mV/div to 20 V/div vertical range, USB 2.0 power and data, dimensions of 200 mm × 140 mm × 35 mm, and a weight under 500 g. The device operates from +0 °C to +45 °C and complies with FCC, CE, and RoHS standards.
