Electronics Test & Measurement measurement test VNA

Siglent SNA5000A series 2- and 4-port Vector Network Analyzers offer a frequency analysis range of 9kHz up to 8.5GHz with a resolution of 1Hz, a dynamic range of 125dB, and a level resolution of 0.05dB. Product series consists of four models (2- or SIGLENT 4-port, 4.5GHz or 8.5GHz maximum frequency) that support measurements such as scattering,  differential, and time-domain parameters, Q-factor, and filter bandwidth and insertion loss. Units feature measurements that include impedance conversion, movement of measurement plane, limit testing, ripple test, fixture simulation, and adapter removal/insertion adjustments. Bias-tees are also supported. Analyzers provide five types of frequency sweep: Linear-Frequency, Log-Frequency, Power-Sweep, CW-Time, and Segment-Sweep. Operation is simplified with the VNA’s large 12.1” touch-screen display, which operates in addition to traditional front-panel controls.
