The National Instruments PXI-5690 is an RF preamplifier offering fixed gain and configurable gain in a compact single-slot 3U PXI module. The PXI-5690 has gain and noise figure characteristics that optimize dynamic range and sensitivity in National Instruments RF vector signal analyzers. When used with the NI PXI-5660 analyzer, the PXI-5690 extends the testing and monitoring capability of the PXI-5660 down to -165 dBm/Hz. The PXI-5690 can also programmatically bypass its gain by switching to a direct path. This functionality enhances the testing and monitoring performance of the PXI-5660 by adding the previously unattainable capability to shift the dynamic range to easily monitor very weak and very strong signals.

•2-channel fixed or programmable gain with bypass
•-165 dBm/Hz extended noise floor for NI PXI-5660
