The enhancements to the Signal Studio software include generation of the metrology-grade 256QAM reference signals needed to test physical downlink shared channel (PDSCH) and physical multicast channel (PMCH) implementations.
The software’s updated Test Model Wizard now supports the new 256QAM Rel-12 test models, E-TM2a and E-TM3.1a, used to evaluate BTS power amplifiers.
The software updates also support the downlink shared channel (DL-SCH) with limited data rate channel coding for the new Category 0 UE defined by Rel-12. These Internet of things (IoT) devices will use robust machine-type communications (MTC) based on low data rates, limited modulation schemes and limited multiple-input/multiple-output (MIMO) functionality, all of which are intended to improve battery life.
Other additions include multi-UE scenarios for eNB load testing through emulation of up to 100 UE devices using a single Keysight X-Series signal generator.
