3 Technical specifications These specifications apply to an E5515C mainframe with Option 003 (or E5515B/T upgraded to equivalent configuration) when used with the E1963A Test Application of firmware revision A or higher, or the E1985A GSM/GPRS/IS-136/WCDMA Test Application of firmware revision B or higher. Specifications describe the test set s warranted performance and are valid for the unit s operation within the stated environmental ranges, unless otherwise noted. All specifications are valid after a 30-minute warm-up period of continuous operation. Supplemental characteristics are intended to provide typical, but non-warranted, performance parameters that may be useful in applying the instrument. These characteristics are shown in Italics and labeled as typical or supplemental. All units shipped from the factory meet these typical numbers at 25 C ambient temperature without including measurement uncertainty. 3GPP W-CDMA Modes of operation: active cell, test mode, CW Resident formats: W-CDMA FDD, R99, June 2001 release Test mode functionality Test mode provides layer 1 functionality only.
