Refer to the exhibit.
In an effort to identify RF characteristics at a customer location, an RF engineer uses the Spectrum Analyzer tool that is shown. Which feature that is native to the Spectrum Analyzer is identified by the exhibit?

B. Duty Cycle

Shouldn’t this be C : Max Hold ?
Because Max hold is shown in the picture which is a feature of the tool.
Real-Time FFT is a method used in spectrum analyzers but not a feature.
