OWON HDS300 Series
A professional 2-channel oscilloscope, a 20,000-count True-RMS multimeter and a built-in 30 MHz waveform generator — 70 to 200 MHz of bandwidth with dual-battery power, in the palm of your hand.
A complete portable test bench
The OWON HDS300 Series is a professional handheld instrument that 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 — 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 wfrms/s refresh rate. A bright 3.5″ colour LCD, a dual 18650 battery system for extended runtime and a single USB-C for charging and PC/SCPI control 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.
Three instruments in one
A 2-channel oscilloscope, a 20,000-count True-RMS digital multimeter and a built-in waveform generator, switched with a single key.
30 MHz arbitrary generator
A higher-bandwidth 30 MHz signal source — sine, square, ramp, pulse and arbitrary waveforms — for stimulus and injection right in the field.
Dual-battery, all-day power
A dual 18650 lithium battery system delivers extended runtime; charge and talk to a PC over a single USB-C connection.
20,000-count True-RMS meter
Laboratory-grade True-RMS multimeter: DC/AC voltage and current, resistance, capacitance, diode and continuity.
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, 600 V-rated inputs make it at home in the field, the workshop and the vehicle bay — while up to 200 MHz of bandwidth, deep automation and a True-RMS meter keep it capable enough for serious design and repair work.
