The PXI-1430B RF Downconverter Module is a PXI 3U, 1-slot downconverter module. It works in conjunction with the PXI-1450B Local Oscillator Module to convert microwave signals in the 100 kHz to 2.9 GHz frequency range into baseband intermediate frequency (IF) signals to drive today’s newest generation of digitizers.

The PXI-1430B RF Downconverter Module is intended for use in applications such as synthetic instrumentation, microwave receivers, signal intelligence, and anywhere a microwave signal needs to be down converted to a baseband frequency for data capture, analysis, and measurement. When combined with a companion high-speed digitizer (> 1 Gs/s) and user-provided software (e.g., LabVIEW®), the PXI-1430B provides a total measurement solution in support of microwave test and measurement applications within the 100 kHz to 2.9 GHz frequency range.
