Does the ESG or MXG with N7625B Signal Studio support the UE receiver tests?

Yes, the E4438C (ESG) or N5182A (MXG) with the N7625B LTE TDD signal studio can generate both LTE TDD downlink and uplink signals. So it can be used for receiver components (such as power amplifiers and transmitter, receiver, or transceiver RFICs) and UE receiver tests. But since many of the UE receiver tests in the 3GPP standards are not yet completely defined, we will keep the solution updated following on the standards changes.
