OWON HSA3140-R Handheld Real-Time Spectrum Analyzer — 9 kHz to 14.0 GHz
Handheld real-time spectrum analyser reaching 14 GHz in a 4.7 kg instrument, with 100 MHz of real-time analysis bandwidth, a 6.25 us 100% probability of intercept and GPS track logging. A pure analyser: no tracking generator or vector network analyser is available at this frequency, and the RF input is a 2.92 mm connector.
9 kHz to 14.0 GHz, in real time and in the field
The OWON HSA3140-R is a handheld real-time spectrum analyser covering 9 kHz to 14.0 GHz — enough for X-band radar, satellite links, point-to-point microwave backhaul and every band below them. Rather than sweeping the band one slice at a time, it digitises a 100 MHz span continuously, so any event lasting 6.25 µs or longer is captured with 100% probability of intercept instead of falling between sweeps.
At this frequency there is no tracking generator and no vector network analyser — the HSA3140-R is a pure analyser, and the RF input is a 2.92 mm connector rather than N-type. What it does bring is reach: 14.0 GHz in a 4.7 kg handheld, with the same 100 MHz real-time engine, the standard 20 dB preamplifier, −165 dBm/Hz DANL, GPS track logging and the 8-inch multi-touch screen.

Nothing gets past it
A swept analyser looks at one slice of the band at a time and loses whatever happens while it is looking somewhere else. The HSA3140-R watches 100 MHz at once and catches any burst longer than 6.25 µs — every time, not on average.
What the HSA3140-R does
Real-time capture
100 MHz real-time analysis bandwidth, 60 dB real-time spurious-free dynamic range and a 6.25 µs 100% POI — probability density, waterfall, 3D and power-vs-time views with a 50,000-frame spectrogram.
GPS map & bearings
A GPS receiver, directional-antenna input and gyroscope log position, route, level and antenna bearing on a map on the instrument — so a site walk becomes a triangulation.
Reach without a rack
14.0 GHz in a 4.7 kg handheld with a 2.92 mm RF input, a 20 dB standard preamplifier and 1 Hz resolution bandwidth — microwave measurements taken where the equipment actually is.
Automatable
LAN, USB Type-C host and micro-USB device with SCPI, LabVIEW and IVI over USB-TMC, VXI-11, socket or Telnet — plus NI-MAX, a web browser interface and OWON Spectrum Vision.
Ideal for
- Field work across X-band radar, satellite links, point-to-point microwave backhaul and every band below them
- Interference hunting with the GPS map and a directional antenna
- Spectrum monitoring, site survey and commissioning
- Microwave link, radar and satellite work away from the bench
Measurement functions
- Real-time views: density spectrum, waterfall, 3D, power vs. time
- CHP, ACPR, OBW, CNR, harmonic, monitor, CCDF, SEM, TOI
- AM, FM and PM modulation analysis
- EMI pre-compliance with 200+ built-in templates (option)

Compare the HSA3000-R range
One platform, four frequency ranges. The real-time engine, the GPS logging, the preamplifier and the 8-inch touchscreen are identical on all four — above 7.5 GHz the tracking generator, the vector network analyser and the cable-and-antenna mode are not available, and the RF input changes to 2.92 mm.
