OWON HSA3075-R Handheld Real-Time Spectrum Analyzer — 9 kHz to 7.5 GHz
Handheld real-time spectrum analyser, 9 kHz to 7.5 GHz — the full Wi-Fi 6E band and 5G n77/n78/n79 — with 100 MHz of real-time analysis bandwidth and a 6.25 us 100% probability of intercept. GPS map and track logging as standard; tracking generator, vector network analyser and cable-and-antenna test available as a factory option.
9 kHz to 7.5 GHz, in real time and in the field
The OWON HSA3075-R is a handheld real-time spectrum analyser covering 9 kHz to 7.5 GHz — enough for everything up to and including the full Wi-Fi 6E band at 5.925–7.125 GHz, plus 5G n77/n78/n79. 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.
Options turn it into two more instruments. A tracking generator over 100 kHz – 7.5 GHz, a vector network analyser measuring S11 and S21 with 90 dB of dynamic range, and a cable-and-antenna mode with distance-to-fault, return loss and VSWR mean the same box that finds the interference also tests the feeder you suspect. Add the standard GPS map, a 20 dB preamplifier, −165 dBm/Hz DANL and an 8-inch multi-touch screen, and one instrument covers hunting, survey and commissioning.
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 HSA3075-R watches 100 MHz at once and catches any burst longer than 6.25 µs — every time, not on average.
What the HSA3075-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.
VNA & cable test (option)
A tracking generator over 100 kHz – 7.5 GHz, vector S11/S21 with 90 dB dynamic range and a Smith chart, plus distance-to-fault, return loss and VSWR on feeders and antennas.
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.

The HSA3075-R shares its chassis, screen, keypad and connector panel with the HSA3036-R, and these are photographs of that chassis — the front-bezel model badge is out of frame rather than showing you another model's. Ask us for a photograph of the exact unit before you order if that matters.

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.
