Page 5: About The Extension Unit
1 About the Extension Unit 1.1 Features The R&S ZVAX-TRM is a configurable extension unit for the R&S ZVA and R&S ZVT families of vector network analyzers, enabling enhanced measurements with high sig- nal power, pulsed stimuli, two-tone stimuli or a combination thereof. The focus is on performing measurements on active devices such as T/R modules, receivers or power amplifiers without the need to reconnect the DUT ("single connection measurement"). - Page 6 The extension unit is fully controlled by the analyzer firmware (V3.30 or higher); the management connection is established via USB. Internal components and external user paths of the R&S ZVAX-TRM can be selectively enabled/disabled from the firm- ware on a per-channel basis. Also, the adequate a-wave access can be selected per channel and port.
