OWON ADS900A Series
A modern 12-bit benchtop scope with a 7-inch multi-touch Android display, up to 250 MHz bandwidth and 2.5 GSa/s sampling — with an optional built-in waveform generator and 16-channel logic analyser. From €375.
High-resolution measurement, a modern touch experience
The OWON ADS900A series is a compact, modern benchtop oscilloscope built around a 12-bit ADC — 16 times the vertical resolution of a standard 8-bit scope. That lets it reveal the small detail on large signals — power-supply ripple, sensor noise, audio distortion — that an 8-bit instrument buries in quantisation. Choose 125 or 250 MHz bandwidth in 2 or 4 channels.
Every model runs a responsive Android operating system on a 7-inch multi-touch capacitive display, with up to 2.5 GSa/s sampling, 100M record length and a 50,000 wfms/s capture rate. Serial-bus decoding (RS232/UART, I²C, SPI, CAN, LIN), FFT, waveform math and pass/fail testing come as standard — and an optional built-in waveform generator and 16-channel logic analyser turn it into a complete mixed-signal bench.
Why the ADS900A
12-bit resolution, a touchscreen Android interface and optional generator + logic analyser — a mixed-signal bench in one compact instrument.
12-bit high resolution
A 12-bit ADC gives 4096 vertical levels (vs 256 on an 8-bit scope), resolving ripple, noise and small signal detail with far greater clarity — from just €375.
7-inch Android multi-touch
A 1024 × 600 capacitive touchscreen on a responsive Android OS: pinch-to-zoom waveforms, tap menus and navigate as easily as a tablet.
2.5 GSa/s & 100M memory
Up to 2.5 GSa/s real-time sampling and 100M record length capture long, fast events in fine detail — with FFT, math, pass/fail and serial decoding built in.
Optional AWG + 16-ch logic analyser
Add a built-in arbitrary/function generator and a 16-channel logic analyser to any model — plus HDMI output, LAN, USB and Wi-Fi for a full mixed-signal bench.
Who it’s for & best applications
The ADS900A suits anyone who needs to see small signal detail clearly — and to fold a generator, logic analyser and decoder into a single compact bench instrument.

Base scope
The 12-bit oscilloscope with serial decoding, FFT, math and pass/fail as standard.
+ AWG generator
Built-in arbitrary/function generator: sine to 30 MHz, square, ramp, pulse and arbitrary waveforms with AM/FM/PM/FSK modulation.
+ 16-channel LA
Built-in 16-channel logic analyser (D0–D15) for mixed-signal and digital-bus debugging. Combine with the AWG for a full mixed-signal bench.
All models: 7-inch 1024 × 600 multi-touch display, 12-bit, up to 2.5 GSa/s, 100M record, serial decoding, FFT and pass/fail. Prices include VAT and are the base configuration; click a model for the AWG/LA options and current stock.
