Brief description

The configurable R&S^®ZVAX‑TRM extension unit is used together with an R&S^®ZVA / R&S^®ZVT (the R&S^®ZVAX-TRM24/40/50/67 can be combined with any R&S^®ZVA8/24/40/50/67 or R&S^®ZVT8/20 network analyzer; the extension unit is supplied as standard with the RF interconnection cables for the corresponding R&S^®ZVA24/40/50/67 model) network analyzer to provide signal conditioning for demanding measurements on active DUTs. For example, it allows measurements on pulsed signals or noise figure measurements on transmit/ receive (T/R) modules. Together with an R&S^®ZVA network analyzer, the R&S^®ZVAX‑TRM provides costomized test sets for applications up to 24/40/50/67 GHz (restrictions on some options for the 67 GHz model).

Features & Benefits

Configurable test system for characterizing T/R modules
- R&S^®ZVAX-TRM decouples signal conditioning from the network analyzer
- Fewer options needed for the network analyzer itself, reduced investment costs
- Basic configuration supports high-power two-port measurements up to +43 dBm
- Test set can be expanded with options
- Signal access points in the R&S^®ZVAX-TRM for integrating external components and instruments
Excellent performance data for measurements on T/R modules
- Measure a T/R module’s characteristics in both directions
- E.g. bidirectional pulse measurements
- High output power levels even with a fully configured R&S^®ZVAX-TRM
Customized configuration
- R&S^®ZVAX‑TRM base unit
- R&S^®ZVAXxxB712/B73 pulse modulators
- R&S^®ZVAXxxB112/B134 output amplifiers
- R&S^®ZVAXxxB213/B224 combiners
- R&S^®ZVAXxxB31/B32 Pre-amplifier, receiver path 1/2
Typical system configurations
- Measurements on T/R modules with combined transmit/ receive ports
- Measurements on T/R modules with an input circulator (three ports)
- High-power and hot S₂₂ measurements
