As single-box solution, E6610A aids those involved with remote radio head (RRH) testing. Dual RF Tx/Rx channels and Common Public Radio Interface (CPRI) optical interface are included to emulate connection between the RRH and baseband unit. Capabilities cover testing LTE-FDD and LTE-TDD RRHs over 700 MHz to 2.7 GHz range, and functionality further enables testing of complete RRH in both uplink and downlink modes.
