OWON HDS320S 200MHz 2CH Handheld Oscilloscope
OWON HDS320S handheld oscilloscope: 200 MHz, 2 channels, 1 GSa/s, with 20,000-count True-RMS multimeter and 30 MHz waveform generator. 3.5" LCD, dual 18650 battery, USB-C.
200 MHz flagship performance, handheld
The OWON HDS320S is the flagship of the HDS300 series: a 200 MHz, 2-channel digital oscilloscope with 1 GSa/s real-time sampling, a 20,000-count True-RMS multimeter and a built-in 30 MHz arbitrary waveform generator — bench-class bandwidth in a rugged, palm-sized device.
A ≤ 1.75 ns rise time and a 2 ns/div timebase resolve the fastest edges in the range, while the 8K record length, 10,000 wfms/s refresh rate and 2 × 2600 mAh dual-battery power keep it dependable through a full day in the field. If you want one handheld instrument that will not run out of bandwidth, this is it.
One tool, three instruments
Oscilloscope, meter and signal source in one housing — with one-key switching and professional-grade specs.
Three instruments, one key
A 200 MHz 2-channel oscilloscope, a True-RMS digital multimeter and an arbitrary waveform generator in one housing — switch between them with a single key press.
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.
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 (2 × 2600 mAh) 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
With 200 MHz of bandwidth, the HDS320S is made for fast digital and embedded work, RF-adjacent debugging and demanding field service — laboratory-grade measurement away from the bench.
