High rez 20MHz oscilloscopes deliver up to 8 channels

PICO TECHNOLOGY PicoScope PS4000A Series of 20MHz USB 3.0-connected PC oscilloscopes providing two, four, or eight high-resolution analog channels. The portable units have a compact footprint with BNC connectors that accept all common probes and accessories. With a high vertical resolution of 12 bits, 20MHz bandwidth, 256MSa buffer memory, and a fast sampling rate of 80MS/s, product has the advanced measurement power and functionality to provide precision results. Units are unlike conventional oscilloscopes with 8-bit resolution and limited capture memory, or card-based digitizers that require an expensive mainframe. The 12 bits of hardware resolution extends to 16 bits using the Resolution Enhancement mode. Scopes include a built-in Signal Generator / AWG, and a SuperSpeed USB 3.0 interface that both powers the instrument and delivers 480Mbit/s communications to the host PC.
