National Instruments' RF vector signal analyzer, RF vector signal generator and PXI Express 18-slot chassis offer flexible RF measurements up to 10x faster than traditional RF instrumentation. These software-defined modular instruments (the PXIe-5663 6.6 GHz RF vector signal analyzer and the PXIe-5673 6.6 GHz RF vector signal generator) are complemented by the PXIe-1075 18-slot high-bandwidth chassis. The PXIe-5663 can perform signal analysis from 10 MHz to 6.6 GHz with up to 50 MHz of instantaneous bandwidth. The PXIe-5673 delivers signal generation from 85 MHz to 6.6 GHz and up to 100 MHz of instantaneous bandwidth. These instruments are suitable for high-speed RF and wireless automated test environments.
