SNA6000A Series
Siglent's flagship vector network analyzer — 100 kHz to 13.5 or 26.5 GHz, in 2- and 4-port versions, with 135 dB dynamic range, very low trace noise and a 12.1-inch touchscreen. A complete options set adds TDR, spectrum, mixer, pulse and material measurement.
One VNA for the whole RF lab
The SNA6000A is built for engineers who characterise RF and microwave components and high-speed digital interconnects: antenna, filter, amplifier and cable/connector designers; signal-integrity and PCB engineers; wireless, radar, satcom and automotive-radar teams; production-test and QA lines; and university RF labs.
With up to 26.5 GHz, 135 dB dynamic range and very low trace noise, it resolves deep filter rejection and isolation with confidence. The 4-port models add differential / mixed-mode S-parameters and TDR for signal integrity, while five sweep types and IF bandwidths to 10 MHz keep production throughput high.
A broad option set turns one instrument into many — time-domain / TDR, spectrum, scalar mixer, pulse and material measurement — and it scales with an SSM5000A switch matrix for multiport test and VDI modules for millimeter-wave. Microwave VNA performance within reach, backed by a 3-year warranty, factory ISO calibration and local European support.
Models
Eight models — 2- or 4-port, 13.5 or 26.5 GHz. The 61xx models add a front-panel jumper (direct receiver access) for advanced measurements.








All models: 135 dB dynamic range · 1 Hz frequency resolution · IFBW 1 Hz – 10 MHz · −55 to +10 dBm source · 0.05 dB level resolution · 12.1″ touchscreen · 3.5 mm NMD connectors.
Measurement capabilities
Far more than S-parameters — the SNA6000A is a full measurement platform.
S-parameters & differential
Full 2-/4-port S-parameters plus differential (mixed-mode) parameters, with SOLT/SOLR/TRL and enhanced-response calibration.
Time domain & TDR
Time-domain analysis (SNA6000-TDA) and enhanced TDR (SNA6000-TDR) locate impedance discontinuities and gate out reflections.
Spectrum analysis
Add a built-in spectrum-analysis mode (SNA6000-SA) to check harmonics, spurs and interference without a second instrument.
Mixer & pulse
Scalar mixer measurement (SNA6000-SMM) and pulse measurement (SNA6000-PM) for frequency-converting and pulsed devices.
Material measurement
Characterise dielectric materials with the material-measurement option (SNA6000-MT).
Analysis tools
Impedance conversion, reference-plane movement, limit & ripple test, fixture simulation and adapter removal/insertion built in.
Applications & advanced measurements
From millimeter-wave device test to high-speed signal integrity and multiport production — the SNA6000A scales to the job.

Extend into mmWave with VDI modules
Pair the SNA6000A with frequency-extender modules to take S-parameter measurements far beyond 26.5 GHz into the millimeter-wave bands — for 5G/6G, automotive radar, satcom and emerging high-frequency components, all driven from the same familiar interface.
Scale up with the SSM5000A switch matrix
Combine the VNA with a Siglent SSM5000A switch matrix to measure many ports and devices automatically — expand well beyond 4 ports for module banks, multiport filters and high-throughput production lines, without constant re-cabling.


Time-domain, TDR/TDT & eye diagrams
The enhanced time-domain option (SNA6000-TDR) turns frequency-domain data into impedance vs. distance, eye diagrams and mask tests — locate discontinuities on PCB traces, connectors and cables and validate high-speed links with adjustable differential or single-ended TDR probes.
Pulse & mixer measurement
With the pulse-measurement option (SNA6000-PM) you can characterise pulsed devices such as T/R modules and radar amplifiers, with flexible pulse profiles and IF-path gain control. The scalar mixer option (SNA6000-SMM) adds frequency-converting device test for mixers and converters.

Frequently asked questions
Siglent SNA6000A vector network analyzer.
What's the difference between the models?
Choose 2- or 4-port and 13.5 or 26.5 GHz. The 60xx models (e.g. SNA6034A) are the standard versions; the 61xx models (e.g. SNA6134A) add a front-panel jumper interface for direct receiver access and advanced configurations.
Which options can I add?
Time-domain analysis (TDA), enhanced TDR, spectrum analysis (SA), scalar mixer measurement (SMM), pulse measurement (PM), material measurement (MT) and a high-performance reference source (HPR). Most are software options.
What calibration do I need?
Either an SEM5000A electronic calibrator (ECal) for fast one-connection calibration, or a mechanical kit matched to your connector and frequency — N-type up to 18 GHz, 3.5 mm up to 26.5 GHz, plus a waveguide kit. We'll recommend the right one.
Can it do TDR / signal-integrity work?
Yes — with the TDR option and adjustable differential or single-ended TDR probes (ADP-18/26, ASP-18/26) for impedance and signal-integrity measurements to 26.5 GHz.
How is it controlled / connected?
A 12.1-inch touchscreen plus USB and Gigabit LAN, with HDMI/DVI/DP video out and an optional USB-GPIB adapter for ATE integration.
Are calibration certificates available?
Yes. Every unit ships with a factory ISO calibration certificate, and we offer accredited ISO/DKD (DAkkS) calibration and recalibration on request — see our calibration services.
