5-Filter PXI IF Conditioning Module—The PXIe‑5694 IF conditioning module is well suited for spectrum monitoring applications in which some interfering signals are spaced too close in frequency to the measurement signal. It provides additional filtering in the IF stage. The PXIe‑5694 adds a wide range of analog filters centered at the final IF frequency to help you balance selectivity and measurement speed. These analog filters prevent adjacent high-power signals from overloading the analog‑to‑digital converters in the digitizer. This capability helps resolve low-power signals and increases the probability of intercept.
