A Layer 1 sweep was performed at a customer location, and you are asked to review a capture taken
during the survey.What is the meaning of the chart shown in the exhibit and how should it be interpreted?

A.
Real Time FFT means Real Time First Fundamental Trace and shows the value of the first signal
detected on each frequency at each sweep interval.

B.
Real Time FFT means Real Time Fast Frequency Timing and shows the RF pulses measured by the
Layer 1 sweep tool.

C.
Real Time FFT means Real Time Fast Fourier Transform and shows the max value of the signal
detected on each frequency in real time.

D.
Real Time FFT means Real Time Frequency Fundamental Texture and shows the value of the noise
background generated by the card used to perform the Layer 1 sweep.
