E1969A TD-SCDMA GSM fast switch test application for the 8960 Series 10 (E5515C/E) wireless communications test set provides critical capabilities for verifying the performance of your TD-SCDMA/TD-HSDPA/TD-HSUPA mobile devices with both signaling and non-signaling modes. The GSM/GPRS/EGPRS test application is bundled together with TD-SCDMA options in E1969A to meet the test requirements for dual-mode wireless devices. With the fast switch function built into the E1969A, you have the flexibility to easily switch wireless formats between TD-SCDMA and GSM/GPRS/EGPRS. With additional feature options, E1969A also provides network emulation and mobile device design, as well as integration and validation test tools designed specifically for the needs of wireless developers. It also offers the inter-RAT scenarios, highest sustained packet-switched data rates, 3GPP standards-compliant RF measurements, and real-time protocol logging. The single-channel GPS source, simulating one satellite signal, and FM broadcast signal source are additional capabilities available with E1969A to speed GPS and FM receiver calibration. Note: Look for the November release of E1969A software containing real time encoding/decoding test capability.
