Users can validate DUT performance Over-the-Air (OTA) with chambers designed for different for different test cases across the device workflow.

The E7770A Common Interface Unit (CIU) provides a bi-directional intermediate frequency (IF) interface to the device under test by up- or down-converting a sub-6GHz uplink or downlink RF signal into a 6 – 12 GHz IF signal. It also provides control, power and local oscillator frequency input to the M1740A mmWave Transceiver for 5G remote radio heads (RRHs), which up-converts the IF signal to mmWave frequency bands and down-converts the mmWave frequency bands to IF. As an up/down converter and RRH controller, the CIU supports the extension of the frequency coverage from sub-6GHz to high IF (6-12 GHz) and mmWave bands.
