Siglent SNA6124A, 4-Port Vector Network Analyzer, 100 kHz–13.5 GHz

The Siglent SNA6124A is a high-performance 4-port vector network analyzer (VNA) featuring a frequency range from 100 kHz to 13.5 GHz. It supports S-parameter, differential, and time-domain (TDR) measurements, making it suitable for analyzing filters, amplifiers, cables, and passive devices. The system offers multiple sweep modes—Linear, Log-Frequency, Power, CW-Time, and Segment Sweep—and supports SOLT, SOLR, TRL, and Enhanced Response calibration. Its 12.1-inch touchscreen display and high-dynamic-range receiver facilitate precise and efficient measurements in R&D, production, and field-testing environments.
