STO-1020313-T-E1 is a compact W-Band vector network analyzer (VNA) frequency extender transmit (Tx/Ref) module that extends lower frequency VNA signals to 75 to 110 GHz. It is compatible with modern VNA from Anritsu, Copper Mountain, Keysight, and Rohde & Schwarz that operate at 20 GHz or higher frequencies. The VNA needs dual sources to be extended. This frequency extender, when paired with compatible receiver, can achieve a dynamic range up to 120 dB and can be used to measure one-path transmission (S21 or S12) through DUT. An AC to DC Power adapter and Proxi-Flange™ Contactless Flanges (STQ-WG-10010-FB-CF and STQ-WG-10025-FB-CF), are included. The Eravant calibration kit (STQ-TO-10-S1-CKIT1) and Wave-Glide™ Rail System (STQ-TL-RW-S10-M1) are highly recommended to complete the W-Band VNA test set. VNA extender is packaged individually in a rugged equipment box with additional hardware and tools.
