Publication number: 20240106551Abstract: A radio frequency (RF) test device such as a spectrum analyzer may include an RF attenuator to attenuate a received RF signal; a mixer to down-convert the attenuated RF signal; an IF attenuator to attenuate the down-converted signal; an analog-to-digital converter (ADC) to digitize the attenuated, down-converted signal; and a processor, which may select attenuation values for one or more of the RF attenuator and the IF attenuator based on an error magnitude vector (EVM) analysis, an RF signal type, and/or a signal level at an input of the ADC. The processor may use a look-up table for the selection. Initial attenuation values may be selected based on an expected RF signal type, RF signal frequency, and/or RF signal bandwidth. The attenuation values may also be selected in an iterative manner stepping the attenuation values up or down.Type: ApplicationFiled: September 27, 2022Publication date: March 28, 2024Applicant: VIAVI SOLUTIONS INC.Inventors: Bon-Jin KU, Seung-Gon HONG, Chang-Hyun PARK
