SNA5032A 26.5 GHz 2-Port Vector Network Analyzer | Siglent
The Siglent SNA5032A is the flagship two-port of the SNA5000A series, reaching 26.5 GHz to cover the full K-band for radar, satellite communications, automotive radar components and advanced microwave research. It delivers the family's 125 dB dynamic range, 1 Hz frequency resolution and 10 Hz–3 MHz IF bandwidth across the entire span, so demanding low-loss and high-isolation devices remain measurable right up to 26.5 GHz — with five sweep types and a −55 to +10 dBm source for precise stimulus control.
Product overview
The SNA5032A is a 2-port vector network analyzer covering 100 kHz – 26.5 GHz with up to 125 dB of dynamic range. Full S-parameters, 1 Hz frequency resolution and an IF bandwidth from 10 Hz to 3 MHz make it a precise, complete instrument for RF and microwave component and network characterisation.
Beyond magnitude-and-phase S-parameters it adds differential, receiver and time-domain (TDR/TDT) analysis, five sweep types, automatic fixture removal for de-embedding and limit / ripple testing. Built-in bias-tees and a large 12.1-inch capacitive touchscreen round out an automation-ready platform — with optional spectrum-analysis, mixer, gain-compression, pulse and material-measurement modes activated by licence.
Key highlights
100 kHz – 26.5 GHz, 2-port
Full forward and reverse S-parameter characterisation through 2 N-type test ports.
125 dB dynamic range
Up to 125 dB dynamic range with a −55 dBm to +10 dBm source for high-isolation and low-loss devices.
1 Hz res · IFBW 10 Hz–3 MHz
1 Hz frequency resolution and an IF bandwidth from 10 Hz to 3 MHz trade sweep speed against trace noise.
Time-domain, TDR & TDT
S-parameter, differential, receiver and time-domain analysis, with automatic fixture removal for de-embedding.
Built-in bias-tees
Integrated bias-tees feed DC to amplifiers and other active parts through the RF port — no external tee.
12.1-inch touchscreen
A large capacitive touchscreen with multi-window display, plus LAN/USB/HDMI and SCPI/LabVIEW/IVI remote control.
Core capabilities
Full 2-port S-parameters
Measure S11 and S21 with vectored magnitude and phase — the basis for reliable RF component and network characterisation, with output power adjustable from −55 to +10 dBm.
Time-domain, TDR & TDT
Transform to the time domain for TDR/TDT, gating and fault location — pinpoint impedance discontinuities and characterise interconnects, cables and connectors (SNA5000-TDA / TDR options).
Fixture error compensation
Automatic fixture removal, de-embedding and adapter removal/insertion move the measurement plane onto the device under test, calibrating out cables, adapters and test boards.
Five sweep types
Linear-frequency, log-frequency, power-sweep, CW-time and segment-sweep modes give full control over stimulus, resolution and acquisition time.
Bias-tees for active devices
Built-in bias-tees feed DC to amplifiers and other active parts through the RF port, and gain-compression and pulse options extend active-device testing.
Modern connectivity
LAN, USB device & host, HDMI video output and an optional USB-GPIB, plus an optional high-stability OCXO reference (SNA5000-HPR).
Advanced measurement suite
The SNA5000A goes far beyond basic S-parameters — a multi-window platform that grows from a network analyzer into a full RF measurement system.
Arrange up to 25 traces across multiple windows and channels to view S-parameters, time-domain and Smith-chart formats side by side on the 12.1-inch screen.
Transform S-parameters into the time domain to locate reflections, impedance changes and discontinuities along cables, PCB traces and connectors.
Advanced time-domain reflectometry and transmission for fault location and impedance profiling of interconnects and channels, with step / impulse stimulus.
The optional SA function turns the VNA into a spectrum analyzer for harmonics, spurious, channel power and occupied bandwidth on the same instrument.
Characterise frequency-converting devices — mixers and converters — with scalar (SMM) and vector (VMM) mixer-measurement options.
The optional MT package measures the dielectric properties (permittivity / permeability) of materials directly from the S-parameters.

Factory calibration certificate
You’ll need a calibration kit
A vector network analyzer is only as accurate as its calibration. The SNA5032A does not include a calibration standard — pair it with an ECal module or a mechanical cal kit (rated for 26.5 GHz) so you can measure to a trusted reference plane from day one.
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 your device — without it, S-parameter readings can’t be trusted.
You re-calibrate every time the cabling, frequency span, output power or temperature changes, so a good kit is used constantly — it is essential, not optional, for any VNA.
One-connection SEM-series ECal modules calibrate in seconds, or use precision N-type, 3.5 mm and 2.92 mm mechanical kits as reference standards.
Software licences & options
Full calibration (SOLT, SOLR, TRL, ECal), impedance conversion, fixture simulation and five sweep types are standard. These eleven licences expand the SNA5032A into spectrum, mixer, gain-compression, pulse and material measurement — all activated electronically.
Adds a spectrum-analyzer mode — harmonics, spurious, channel power, ACPR and occupied bandwidth on the same instrument.
Transforms S-parameters into the time domain to locate reflections, impedance changes and discontinuities.
Advanced TDR/TDT for fault location and impedance analysis of cables, PCB traces and connectors, with step / impulse stimulus.
Mathematically de-embeds test fixtures to measure SMD, PCB and non-coaxial devices, with Touchstone export.
High-performance OCXO time-base for tighter frequency stability in demanding, drift-sensitive measurements.
Measures conversion loss and match of mixers and frequency converters without a phase reference.
Full vector characterisation of mixers and converters — magnitude, phase and group delay of the conversion.
Swept and 2-D gain-compression measurements (P1dB) for amplifiers and active devices.
Pulsed-RF S-parameter measurements for devices that operate or are tested under pulsed conditions.
Extracts dielectric properties (permittivity / permeability) of materials directly from the S-parameters.
Guided performance-verification test package for periodic instrument checks and calibration validation.
