Key Features
2, 4 or 8 Analog Channels
Choose the channel count that matches the application, from two-channel lab work to eight-channel multi-sensor and power measurements.
12-bit Hardware Resolution
Higher vertical resolution than basic 8-bit scopes helps reveal smaller waveform details in audio, ultrasonic, vibration, power and sensor work.
256 MS Deep Capture Memory
Long record length supports detailed analysis of extended events, serial-bus activity and low-speed mechanical or physical signals.
Built-in 14-bit Generator and AWG
Integrated stimulus output supports function generation and arbitrary waveform generation without adding a separate bench source.
USB 3.0 PC Oscilloscope Workflow
SuperSpeed USB 3.0 powers the instrument and transfers data to the host PC for waveform viewing, logging and automated control.
Advanced Analysis Tools
DeepMeasure, serial decoding, digital triggering, math functions, spectrum analysis and segmented capture support engineering debug.

Applications
Education
High-resolution multi-channel oscilloscope for instrumentation, signals, sensors and measurement laboratories.
Mechanical / Vibration
Multi-channel low-frequency and vibration measurement with long records and high vertical resolution.
Power Electronics
Observe control, gate-drive, current-sense and low-voltage power signals with several analog channels.
NDT / Ultrasonic
Capture ultrasonic and non-destructive testing waveforms with 20 MHz bandwidth and deep memory.
Production Test
Use PicoSDK and USB control for compact multi-channel automated measurement stations.
Research
Multi-sensor scientific measurement where higher resolution and channel count matter more than GHz bandwidth.
