OWON TAO3072(A) 2CH 70MHz Tablet Digital Oscilloscope
OWON TAO3072 / TAO3072A Handheld Oscilloscope is a compact dual-channel scope with 70 MHz bandwidth, up to 1 GSa/s real-time sampling, and 40 Mpts memory depth. Equipped with a large 8″ TFT LCD (800×600) and a portable design, it is perfect for field engineers, service technicians, and education labs.
-
TAO3072: Standard 8-bit resolution for general-purpose testing.
-
TAO3072A: Advanced model with switchable 8-bit / 12-bit / 14-bit resolution for higher precision and more detailed signal analysis.
70 MHz on an 8-inch touchscreen
The OWON TAO3072 is the most affordable way into the TAO3000 tablet platform — a 70 MHz, 2-channel digital oscilloscope behind a large 8″ multi-touch capacitive display, with a 4½-digit multimeter and data logger built into the same housing.
It samples at 1 GSa/s on a single channel, stores up to 40 Mpts and redraws at 45,000 wfms/s, so long captures and rare glitches stay visible. Pinch, swipe and tap the waveform the way you would on a tablet — or use the rotary knobs when your hands are dirty.
Why the TAO3072
A bench oscilloscope, a multimeter and a data logger behind one 8-inch touchscreen — light enough to carry, quick enough to actually enjoy using.
8″ multi-touch screen
A bright 800 × 600 capacitive display — pinch to zoom, swipe the timebase and tap menus. Rotary knobs and shortcut keys are still there when you want them.
2 channels plus a real meter
Two BNC channels at 70 MHz sit next to dedicated multimeter terminals, with LAN, USB host, USB device and a Pass/Fail trigger output on the side panel.
4½-digit multimeter & logger
A 19,999-count auto-ranging meter shares the screen with the scope: DC/AC volts to 1000 V / 750 V, 10 A current, resistance to 100 MΩ, capacitance, diode and continuity — plus data logging.
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 70 MHz across 2 channels on a touchscreen you can carry, the TAO3072 is made for general electronics, audio, power-supply and education work, where signals stay well below the tens of megahertz and portability matters most.
- 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 70 MHz with a ≤ 5.0 ns rise time
- Multimeter measurements and data logging alongside scope work
Choose your version
Click a version below and it is selected in the picker at the top of this page — the price and the Add to cart button follow immediately. The “A” versions swap the 8-bit ADC for one that is switchable between 8, 12 and 14 bits — more vertical detail and a lower noise floor, at a lower sample rate in the higher-resolution modes. The Wi-Fi option adds the wireless module, so the OWON app on your phone or tablet can mirror the screen, control the instrument and store waveforms.
Prices shown incl. VAT, exactly as listed in the variant picker above. All versions share the same 70 MHz bandwidth, 2 channels, screen, memory and connectivity.
