[. . . ] PRODUCTSHEET Product: TEMSTMAutomatic­ScanningReceiverUnit SRU ­ SCANNING RECEIVER UNIT FOR TEMSTM AUTOMATIC SRUs (Scanning Receiver Units) are lightweight and versatile devices dedicated to GSM andWCDMAscanning. OneortwoSRUscanbe connectedtoTEMSAutomaticRTUs(RemoteTest Units)performingautonomousdatacollection. Each SRU is a standalone device that can be conveniently moved betweenRTUsasdictatedbytestingrequirements. [. . . ] InGSMnetworks, theSRUundertakesRSSIscanningofselectedchannels orentireGSMbands.
