The Rohde & Schwarz ZNBT20 is an 8-port vector network analyzer delivering simultaneous two-port measurement capability at each port across 100 kHz to 20 GHz. Built for multiport device characterization, it enables parallel testing of multiple DUTs or comprehensive analysis of single multiport components. The architecture combines high dynamic range up to 140 dB with electronically adjustable output power and sweep times as fast as 2.5 ms for 201 points, making it suitable for aerospace, defense, and telecommunications applications.
