The IFR Aeroflex Cobham 3070A is a high-performance PXI wideband RF digitizer module that down-converts and digitizes RF signals across 250 MHz to 6.0 GHz, delivering amplitude- and phase-corrected digital IF or IQ data pairs. Built for R&D and manufacturing test environments, it handles instantaneous bandwidths to 160 MHz, making it ideal for wide-bandwidth systems including WLAN 802.11ac, radio communications, wireless, radar, and electronic warfare testing.
