The Rohde & Schwarz ZNLE3 is a two-port Vector Network Analyzer delivering full S-parameter measurements across 1 MHz to 3 GHz (expandable to 100 kHz with the R&S®ZNLE-B100 option). Built as a standalone instrument with integrated Windows 10 PC and 10.1″ capacitive touchscreen, it eliminates external computing requirements and enables immediate operation after power-on. The ZNLE3 combines laboratory-grade measurement performance with field-portable form factor, making it ideal for design verification, production testing, and service applications.
