When there is an active connection between the UE and the test set, the UE can perform measurements on the test set's downlink signal and report the measurement results. By pressing the Send Measurement Request (F1) on the front panel or sending the CALL:MS:REPorted:MEASurement:REQuest command, the test set sends a single measurement control message to the UE, with the following measurement information:
the Measurement type is Intra-frequency;
the Measurement quantity is P-CCPCH RSCP;
the Measurement reporting criteria is Periodical, with the reporting interval to be 250ms.
You can view the measurement result either from the front panel, or retrieve it using the GPIB command (See CALL:MS:REPorted[:CELL]:PRIMary:CCPChannel:RSCP?).
P-CCPCH RSCP (Received Signal Code Power): the received power on P-CCPCH. The reporting range for P-CCPCH RSCP is from -120 to -25 dBm. 3GPP standard TS 25.123 defines the following mapping table of the measurement quantity.

This measurement results can be cleared by sending a new Measurement Request or Partial/Full Preset operation.
