Anritsu‘s patent involves a measurement system and method for testing spurious emissions in mobile terminal signals more efficiently. The system divides the frequency band, measures spurious emissions in each band, and determines pass/fail criteria based on peak power levels. The threshold for pass criteria is lower than the 3GPP standard. GlobalData’s report on Anritsu gives a 360-degree view of the company including its patenting strategy. Buy the report here.

Measurement system for testing spurious emissions in mobile terminals
A recently granted patent (Publication Number: US11965921B2) discloses a measurement system that includes a measurement device and a control device. The control device is equipped with a band division unit, a spurious measurement control unit, and a pass/fail determination unit. The system is designed to measure spurious signals in a signal transmitted from an object to be measured by dividing the measurement frequency band into multiple bands and determining whether the peak power of the spurious signals in each band meets the pass determination criteria. The threshold value for the pass determination criteria is set lower than the standard determination criteria defined by the 3GPP standard.
Furthermore, the measurement system includes a partial band determination unit, a second spurious measurement control unit, and a second pass/fail determination unit. The partial band determination unit identifies a specific bandwidth containing spurious signals that do not meet the pass determination criteria. The second spurious measurement control unit then conducts a more accurate measurement of the spurious signals in the identified partial band. The second pass/fail determination unit evaluates whether the peak power of the spurious signals in the partial band meets the standard determination criteria. This system aims to improve the accuracy of spurious signal measurements by implementing a multi-step process for identifying and measuring spurious signals in the transmitted signal, ultimately ensuring compliance with industry standards and regulations.
