In a radio receiver application, the Spurious-Free Dynamic Range (SFDR) is commonly used in a radio receiver to determine the input power range in which the received signal can be detected in the presence of noise and amplified without nonlinear disturbance. In the traditional sense of an amplifier or transmitter, SFDR is the level where the power of the intermodulation distortion (IMD) products are equal to the noise floor. Characterize and troubleshoot links up to 100 km with a dynamic range of 39 dB Find more problems closer to the splitter than other OTDRs thanks to the highest resolution for PON testing and the shortest PON dead zone available Key Features Handy, lightweight, powerful, tablet-inspired design 7-inch, outdoor-enhanced touchscreen–the biggest Feb 10, 2024 · This paper presents a novel adaptive reconfigurable rectifier architecture for radio frequency energy harvesting (RFEH); in addition, a new metric for high-efficiency dynamic range (DR) is proposed. The following discussion explains the relationships among parameters to help understand and evaluate spectrum analyzer dynamic range specifications. This article shows how to build a front end which achieves a two-tone dynamic range of 111 dB and an intercept point of + 33 dBm with 20 kHz test-tone spacing, RF amplifier on, and using an IF bandwidth of 2. Dynamic range refers to the nominal input power range over which a radio receiver functions efficiently. This is different from the dynamic range that is the concentration range that can be measured without saturation of the detection system.
