OWON TAO3104A 4CH 14bits 100MHzTablet Digital Oscilloscope
The OWON TAO3104 100MHz Digital tablet oscilloscope with a Touchscreen 8'' LCD is the new portable Tablet USB Oscilloscope series that OWON has brought to the test and measurement market that requires a more portable and flexible solution in the field.
100 MHz, four channels, up to 14-bit
The OWON TAO3104A is the top of the four-channel TAO3000 family: 100 MHz across four independent channels, with an ADC switchable between 8, 12 and 14 bits for genuinely low-noise, high-detail captures.
It combines 1 GSa/s sampling in 8-bit mode, up to 40 Mpts of record length and a 45,000 wfms/s refresh rate with an 8″ multi-touch capacitive display, multi-level triggers and optional I²C, SPI, UART and CAN bus decoding — all in a rugged, battery-powered tablet you can carry to the job.
Why the TAO3104A
Four channels, an 8-inch touchscreen and a rugged, battery-powered body — a full bench oscilloscope you can carry to the fault.
8″ touch, real knobs
An 800 × 600 multi-touch display for pinch, swipe and tap — with rotary knobs for vertical, horizontal and trigger, and shortcut keys for Autoset, Run/Stop, Single and Copy.
Four BNC channels
Four independent 100 MHz inputs on one panel, with LAN, USB host, USB device, a Pass/Fail trigger output and the probe-compensation signal on the side.
Built for the field
An anti-slip elastic belt on the back for one-handed use, a fold-out bracket to stand it on the bench, and an optional shoulder bag for the trip in between.
Deep memory, fast refresh
A low noise floor, up to 40 Mpts of record length and a 45,000 wfms/s refresh rate catch long and rare events, with ten trigger types, waveform math and optional serial-bus decoding.
Who it’s for & best applications
With 100 MHz across 4 channels on a touchscreen you can carry, the TAO3104A is made for power integrity, sensor and analogue design, embedded bus debugging and demanding four-channel field work.
- Field-service & maintenance engineers
- Embedded, power & general electronics benches
- Education, training labs & advanced makers
- Production test and automated (SCPI / LabVIEW) setups
- Anyone who prefers a touchscreen to a wall of knobs
- General electronics, audio & power-supply debugging
- Microcontroller & embedded development
- I²C, SPI, UART/RS232 & CAN bus decoding (optional)
- Signals up to 100 MHz
- Watching four rails, buses or phases at the same time

Other models in the series
The TAO3074A offers the same 14-bit resolution at 70 MHz; the 8-bit TAO3074 and TAO3104 cover the same bandwidths at a lower price. Every TAO3000 shares the same 8″ multi-touch platform, 1 GSa/s sampling, 40 Mpts memory and 45,000 wfms/s refresh rate — only bandwidth, channel count and ADC resolution differ.
