PXIe, 26.5 GHz, 90 dB PXI RF Attenuator—The PXIe-5699 is a single-channel RF attenuation module that provides 90 dB attenuation and covers from 100 MHz up to 26.5 GHz frequency range. With fast switching speeds of less than 100 ns and an additional passthrough, the PXIe-5699 can extend the gain range of a PXI Vector Signal Transceiver (VST) for high dynamic-range scenarios. You can use the software API as well as digital I/O at the front panel to control the PXIe-5699. Additionally, the PXIe-5699 features internal switches for RF signal routing, allowing you to perform system level calibration.
