Vector Network Analyzer

SIGLENT Vector Network Analyzers have a frequency range of 9 kHz to 8.5 GHz, with 2/4-port models that can quickly deliver reliable scattering, differential, and time-domain parameter measurements.

Compare Models

Wide dynamic range and easy-to-use interface

Siglent’s Vector Network Analyzers cover a frequency range of 9 kHz up-to 8.5 GHz and offer high performance and reliable results in a very user-friendly package. 2 and 4 port models are available with options for high stability reference source, time-domain analysis, and more.


Low noise floor for accurate measurements with a wide dynamic range

Dynamic range can up to 125 dB@10 Hz, for simultaneous in-band and out-of-band testing of filters.

S-parameters and Balance Measurement

Simultaneously view multiple trace and datatypes in different windows to speed characterization.

Enhanced Time-Domain Analysis (TDR)

Measure impedance versus distance, to distinguish between inductive and capacitive transitions. Time-domain gating and TDR is also available.

Embedding and De-Embedding

Eliminate fixture effects quickly.

Calibration Kits

SOLT calibration kits available from DC to 9 GHz. General purpose and precision-level requirements.
