Keysight Agilent E7770A Common Interface Unit
The Keysight E7770A common interface unit (CIU) provides a bidirectional
intermediate frequency (IF) interface to the device under test (DUT) by up- or
down-converting a sub-6 GHz uplink or downlink RF signal into a 6 to 12 GHz
IF signal.
This solution gives you the control, power, and local oscillator frequency input to
the Keysight M1740A millimeter-wave (mmWave) transceiver for 5G remote radio
heads (RRHs). As an up / down converter and RRH controller, the CIU supports
the extension of the frequency coverage from sub-6 GHz to a high IF of 6 to 12 mmWave bands.
