Wide Dynamic Range and Easy-to-Use Interface

Siglent Vector Network Analyzer

Siglent’s Vector Network Analyzers (VNAs) cover a frequency range of 9 kHz to 8.5 GHz and 100 kHz to 26.5 GHz, which offer high performance and reliable results in a very user-friendly package. 2 and 4 port network analyzers 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 26.5 GHz. General purpose and precision-level requirements.
