Siglent SHN920A – 20 GHz Handheld 2-Port Vector Network Analyzer
The SHN920A brings 20 GHz vector network analysis to the tower, the shelter and the workshop. With 110 dB dynamic range, S-parameter and time-domain (TDR) analysis, built-in GPS and a hot-swappable battery, it handles antenna matching, cable fault-finding and 5G component verification on site — while staying accurate enough for lab characterisation back at the bench. Just 3.2 kg.
Product overview
The SHN920A is a handheld 2-port vector network analyzer covering 30 kHz to 20 GHz with up to 110 dB of dynamic range and very low trace noise (0.0005 dB rms). It measures full and differential S-parameters and displays them in every standard format — Smith chart, polar, SWR, log-mag and phase.
A Cable & Antenna Test (CAT) mode with distance-to-fault, a built-in GPS and an internal bias-tee make the SHN920A ideal for installing and maintaining antenna and cable systems in the field. Multiple calibration methods, an 8.4-inch touchscreen and a hot-swappable battery keep it accurate and comfortable anywhere — just 3.2 kg.
Key highlights
30 kHz – 20 GHz, 2-port
Full forward and reverse S-parameter measurement in a rugged handheld.
110 dB dynamic range
High dynamic range with very low trace noise (0.0005 dB rms, 0.015° rms) for precise, repeatable results.
Cable & Antenna Test
CAT and distance-to-fault (DTF) for installing and maintaining antenna and cable systems on site.
Built-in GPS & bias-tee
GPS geotags every measurement, while the internal bias-tee feeds DC to active devices under test.
Optional SA, TDA & TDR
Add spectrum analysis, time-domain analysis and enhanced TDR with eye-diagram simulation and jitter.
8.4-inch touch, 3.2 kg
A spacious capacitive touchscreen and hot-swappable battery in a light, rugged 3.2 kg chassis.
Core capabilities
Full 2-port S-parameters
S11, S21, S12 and S22 plus differential S-parameters (Sdd, Sdc, Scd, Scc), shown as Smith chart, polar, SWR, log-mag, phase and every standard format.
Multiple calibration methods
SOLT, SOLR, TRL, response and enhanced-response calibration — compatible with many cal kits and user-defined standards for different interfaces.
Cable & Antenna Test (CAT)
Assess RF/microwave transmission systems: distance-to-fault, single-port cable loss and antenna matching, right where the system is installed.
GPS & internal bias-tee
Built-in GPS tags measurements with location; the internal bias-tee conveniently supplies DC to the device under test — no external tee.
De-embedding & conversion
Impedance conversion, fixture simulation and adapter removal/insertion move the measurement plane onto the DUT for accurate results.
High dynamic, low noise
110 dB dynamic range and very low trace noise (0.0005 dB rms) meet the need for precise, high-confidence measurement.
Highlights in detail
Multi-window display & every format
The SHN900A shows results the way you need to read them — Smith chart, polar, SWR, log-magnitude, phase, group delay and real/imaginary — across up to four independent windows at once. Each window carries its own channel, trace, format and markers, so you can watch S11 return loss on a Smith chart while S21 insertion loss runs as log-mag right beside it. Switching measurement, format or scale takes a single tap on the 8.4-inch touchscreen, and complete instrument states save and recall in one step for fast changeovers between jobs. The result is a fluid workflow that keeps every parameter you care about in view without diving through menus.
Rugged and ready for the field
Despite integrating a full vector network analyzer, spectrum analysis and cable-and-antenna test, the SHN900A weighs just 3.2 kg in a rugged, protectively-cornered chassis built to travel. The spacious 8.4-inch capacitive touchscreen stays readable on site, and quick-access hard keys plus an intuitive menu structure make standardized measurements fast and repeatable — even in a hurry. Engineers can manage windows, channels and traces directly, and a custom-designed carrying bag stores the instrument and all of its accessories together for safe transport between sites. It is designed to survive the realities of installation, maintenance and commissioning work, not just the lab bench.
Ports & connectivity
Everything you need for field work sits on one rugged top panel. Two precision test ports handle the measurement, a GPS antenna input geotags every result, and an internal bias-tee feeds DC to the device under test — while trigger and 10 MHz reference inputs let you synchronise with other instruments. USB host and device ports cover storage, a mouse or keyboard and PC/SCPI control, and LAN adds full remote operation over VXI-11, Socket, Telnet and the built-in web server, powered from the hot-swappable battery or the 12 VDC input.

Optional accessories
You’ll need a calibration kit
A vector network analyzer is only as accurate as its calibration. The SHN920A does not include a calibration standard — pair it with the SEM5002A ECal module or a mechanical cal kit so you can measure to a trusted reference plane, right in the field.
Browse calibration kits & ECal
A VNA measures relative to its calibration plane. Calibration removes the errors of the cables, adapters and connectors between the instrument and the device under test.
Re-calibrate whenever the cabling, frequency span, output power or temperature changes — so a good kit travels with the instrument on site.
The one-connection SEM5002A ECal calibrates in seconds, or use SOLT, SOLR and TRL mechanical kits and user-defined standards.
Software licences & options
S-parameter measurement, CAT/DTF, calibration and de-embedding are standard. These licences expand the SHN920A further — activated by key. Limited offer: buy the SHN900-TDR and get the SHN900-TDA licence free.
Adds a spectrum-analyzer mode — channel power, ACPR and occupied bandwidth. Marker→SA jumps from VNA to SA at the marker frequency.
Time-domain transformation, windowing and gating for device characterisation from both time and frequency domains.
Reflection and transmission analysis and fault localisation, plus eye-diagram simulation and jitter injection for signal-integrity work.
