R3770 - Advantest Network Analyzers

The R3768/3770 Network Analyzer is a high-performance multi-port analyzer designed with a greater emphasis on measuring passive components.
Higher frequencies are also supported, with the R3768 supporting frequencies from 300 kHz to 8 GHz and the R3770 supporting frequencies from 300 kHz to 20 GHz.
All models have the software fixture function that perform real-time simulation of virtual matching circuits and standardized impedance conversion in addition to S-parameter analysis.
At a high-speed sweep of 5 µs/point, simulations of even complex analysis are accomplished instantly. Moreover, multi-port models can perform software balun simulations and balance parameter analysis. If these models are combined and used with the flexible multi-window and multi-trace functions, they can also measure complex analysis items instantly.
The large high-visibility display is a key factor in improving the analysis efficiency because it enables the simultaneous display of multiport paths in addition to the simultaneous display of fixture simulation traces. 

• Measurement frequency range from 300 kHz to 8/20 GHz based on model configuration
• Very fast sweep rate of 5µs/point
• Model options available for 2 to 4 ports 
• System dynamic range of 125 dB (typical) 
• Balance measurement at 20 GHz
