Abstract
Methods, devices, and systems for coherent time-gated residual spur characterization and correction in signal analyzers. In some cases, the method includes: displaying a signal on the display of the signal analyzer that is present without an input signal being provided to an input of the signal analyzer; establishing a predetermined amplitude threshold above which energy spikes in the signal being displayed on the display of the signal analyzer are considered spurious; automatically identifying one or more spurious energy spikes in the signal being displayed on the display of the signal analyzer based on the predetermined amplitude threshold; and automatically reducing or removing the one or more spurious energy spikes from the signal being displayed on the display of the signal analyzer. The method can be performed using one or more processors, application specific integrated circuits (ASICs), field-programmable gate array (FPGA), or other circuitry on any suitable signal analyzer.
