The Rohde & Schwarz ZC170 Vector Network Analyzer Extender expands VNA measurement capability into the D-band (110 GHz to 170 GHz) through heterodyne downconversion. This specialized instrument converts high-frequency signals to an intermediate frequency (9.167 GHz to 14.167 GHz) for processing by compatible host analyzers, enabling precise S-parameter characterization and RF/microwave analysis at millimeter-wave frequencies.
