Rohde & Schwarz ZVB14 10MHz – 14GHz Vector Network Analyzer with 2 or 4 Test Ports

The Rohde & Schwarz ZVB14 is a vector network analyzer spanning 10 MHz to 14 GHz, available in 2-port or 4-port configurations. Its parallel measurement architecture simultaneously drives multiple ports and captures data in parallel, reducing measurement time by up to a factor of 4 compared to single-generator instruments. The ZVB14 delivers dynamic range exceeding 123 dB between test ports, with optional direct generator/receiver access extending performance by approximately 10 dB.

Maximum output power exceeds +13 dBm per port (2-port) or +10 dBm per port (4-port).
