PicoScope 4000A Series

The PicoScope 4000A Series from Pico Technology delivers 12-bit vertical resolution across a range of 2, 4, and 8-channel USB oscilloscopes designed for applications where signal fidelity matters more than raw bandwidth. With native 12-bit hardware resolution expandable to 16-bit through Resolution Enhancement, input ranges from +/-10 mV to +/-50 V, and a 256 MS capture buffer shared across channels, the 4000A Series resolves fine signal details — power supply ripple, sensor noise floors, and low-level analog signals — that conventional 8-bit oscilloscopes miss entirely.

The 12-bit advantage is the defining characteristic of this series: where standard 8-bit oscilloscopes divide the vertical range into 256 levels, the 4000A’s 12-bit ADC provides 4096 levels — sixteen times the vertical resolution. This makes the series the instrument of choice for characterizing power supply noise, measuring sensor output linearity, and analyzing audio or biomedical signals where small-signal details are critical. Built-in serial protocol decoders for 18 industry standards including CAN, LIN, FlexRay, I2C, SPI, and UART, combined with advanced triggering and the 14-bit arbitrary waveform generator, give the 4000A Series capabilities that rival benchtop instruments at a fraction of the cost and bench space.

The 4224A, 4424A, and 4824A share identical per-channel performance, differing only in channel count: two, four, and eight channels respectively. Engineers select based on their simultaneous observation requirements — the 4224A for focused signal-pair analysis, the 4424A for typical embedded development, and the 4824A for automotive multi-bus or production test fixtures. GSAS Micro Systems supplies all three models with probe kit selection guidance and application support for test and measurement teams across India.
