Frequency Measurement

Mercury offers a range of standard high-performance broadband Digital Instantaneous Frequency Measurement (DIFM) receivers and Digital Frequency Discrimination (DFD), which act as functional building blocks in many military electronic warfare systems. Examples include electronic counter measures (ECM) systems, electronic surveillance measures (ESM) systems and radar warning receivers (RWR).

Our experience in designing components and subsystems for military applications ensures that Mercury DIFMs are reliable and manufacturable. We also offer extensive in-house manufacturing to maintain production rates and keep schedules on time.
