STO-1220305-R-E1 is a compact E-Band vector network analyzer (VNA) frequency extender receive (Rx) module that extends lower frequency VNA signals to 60 to 90 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 can be used to measure one-path transmission (S21 or S12) through DUT when paired with compatible transmitter. When Rx module is paired with Tx/Rx module, the setup can be used to measure reflection at input of DUT and transmission through DUT. An AC to DC Power adapter and Proxi-Flange™ Contactless Flanges (STQ-WG-12010-FB-CF and STQ-WG-12025-FB-CF), are included. The Eravant calibration kit (STQ-TO-12-S1-CKIT1) and Wave-Glide™ Rail System (STQ-TL-RW-S10-M1) are highly recommended to complete the E-Band VNA test set. VNA extender is packaged individually in a rugged equipment box with additional hardware and tools.
