SNA5000A Series
A full-featured vector network analyzer family covering 9 kHz to 26.5 GHz in 2- and 4-port configurations. With up to 125 dB of dynamic range, a −125 dBm/Hz noise floor, 1 Hz frequency and 0.05 dB level resolution and a 12.1-inch capacitive touchscreen, the SNA5000A measures full S-parameters, differential/balanced parameters and time-domain response. SOLT, SOLR, TRL, Response and Enhanced-Response calibration (with optional electronic cal kits) and a deep set of options — spectrum analysis, mixer, material, pulse, gain-compression and time-domain — make it a complete RF and microwave measurement platform for R&D and production.
Vector Network Analyzer
A full-featured vector network analyzer family covering 9 kHz to 26.5 GHz in 2- and 4-port configurations. With up to 125 dB of dynamic range, a −125 dBm/Hz noise floor, 1 Hz frequency and 0.05 dB level resolution and a 12.1-inch capacitive touchscreen, the SNA5000A measures full S-parameters, differential/balanced parameters and time-domain response. SOLT, SOLR, TRL, Response and Enhanced-Response calibration (with optional electronic cal kits) and a deep set of options — spectrum analysis, mixer, material, pulse, gain-compression and time-domain — make it a complete RF and microwave measurement platform for R&D and production.
Every model shares the same platform, 12.1-inch touch interface, calibration methods and option set, so you choose on frequency and port count — then add measurement options and an electronic cal kit to match. siglent.eu is the official EU distributor, with stock, warranty and local support.

Features in depth
A full 2- or 4-port vector network analyzer
At its core the SNA5000A is a fast, accurate VNA: full S-parameters, differential and balanced parameters, and up to 125 dB of dynamic range, driven from a 12.1-inch touchscreen with SOLT, SOLR, TRL and Enhanced-Response calibration.
- 2- or 4-port S-parameters & differential/balanced
- 125 dB dynamic range, −125 dBm/Hz noise floor
- 1 Hz frequency & 0.05 dB level resolution
- SOLT / SOLR / TRL / Response / Enhanced calibration + ECal
Far more than S-parameters
Licence options turn the SNA5000A into a broader measurement platform — scalar and vector mixer measurement, material characterisation, pulse and gain-compression measurement, spectrum analysis and time-domain reflectometry all run on the same instrument.
- Scalar (SMM) & vector (VMM) mixer measurement
- Material (MT) & gain-compression (GC) measurement
- Pulse (PM) measurement & spectrum analyzer (SA)
- Time-domain (TDA) and enhanced TDR + automatic fixture removal (AFR)
Rear panel, calibration & connectivity
LAN, USB and SCPI with an embedded web server make the SNA5000A straightforward to automate; an optional USB-GPIB adapter adds GPIB, and the SEM-series electronic cal kits speed up calibration.
- LAN · USB · SCPI · embedded web server
- Optional USB-GPIB adapter for GPIB buses
- SEM-series electronic calibration kits (2/4-port)
- High-performance reference option (HPR) for stability
