The SI-7138 is a companion to the SI-9138 distributing the master ADC clock to each channel as a reference to synchronize multiple units for sample accurate time tagging.

The SI-7138 and SI-9138 work together to create the SI-8938 subsystem providing phase-coherent, wideband tuning of up to eight tuner channels across the 2 MHz to 6 GHz range. Based on proven RF technology and an open backplane standard, the SI-8938 provides a powerful and low-SWaP software-definable receiver development platform that can easily be integrated and deployed in a range of missions.
