Used stand-alone or integrated on 3U VPX or larger carrier modules, Model 8111 series accepts 800 MHz to 3 GHz RF signals and downconverts them to 225 MHz IF signal suited for A/D conversion by signal acquisition modules. Internal frequency-synthesized local oscillator can be locked to external 10 MHz reference signal for precise tuning accuracy, or on-board 10 MHz OCXO can serve as frequency reference. Each tuner is provisioned with one of 7 different 400 MHz bandwidth preselector filters.
