OWON HDS300 series 3-in-1 handheld oscilloscope (HDS320S)

A complete portable test bench

The OWON HDS300 Series combines a 2-channel digital oscilloscope, a 20,000-count True-RMS multimeter and a built-in 30 MHz arbitrary waveform generator in one rugged, palm-sized device, switched with a single key — a complete portable test bench for field service, automotive, embedded and education work.

Choose from 70, 100 or 200 MHz of bandwidth with up to 1 GSa/s real-time sampling, an 8K record length and a 10,000 wfms/s refresh rate. A bright 3.5″ colour LCD, a dual 18650 battery system for extended runtime and a single USB-C port for charging and PC connection make it precise on the bench and dependable in the field.

One tool, three instruments

A full portable lab — oscilloscope, meter and signal source — with one-key switching and professional-grade specs.

30 MHz arbitrary generator

A built-in signal source up to 30 MHz — sine, square, ramp, pulse and 16 built-in special waveforms at 125 MSa/s and 14-bit resolution, on its own BNC output.

OWON HDS300 multimeter inputs and display

20,000-count True-RMS meter

A laboratory-grade auto-ranging multimeter: DC/AC voltage to 1000 V / 750 V, current to 10 A, resistance, capacitance, diode and continuity — with independent meter inputs.

Dual-battery, USB-C power

Two 18650 lithium cells deliver extended runtime in the field; one USB-C port handles both charging and the Windows PC software connection.

Who it’s for & best applications

The HDS300 Series is built for professionals who need laboratory-grade measurement away from the bench. Its handheld form, dual-battery power and rugged housing make it at home in the field, the workshop and the vehicle bay — while up to 200 MHz of bandwidth and a True-RMS meter keep it capable enough for serious design and repair work.

Ideal for

Field-service & maintenance engineers
Automotive & industrial technicians
Embedded & electronics developers
Installers and on-site troubleshooting
Education, training labs & advanced makers

Typical applications

Power-supply, audio & general electronics debugging
Automotive sensor & ignition diagnostics
Microcontroller & embedded development
Faster digital signals up to 200 MHz (HDS320S)
