Spectrum
The Spectrum trace displays a graph with amplitude on the y-axis
and frequency on the x-axis. The captured IQ data is FFT
processed (fast Fourier transformed) and converted from the time
domain to the frequency domain for display as a spectrum.
Frequency vs. Time
The Frequency vs. Time trace displays a graph with frequency on
the y-axis and time on the x-axis to confirm time variation of the
measured signal frequency.
Power vs. Time
The Power vs. Time trace displays a graph with amplitude on the
y-axis and time on the x-axis to confirm changes in power with time
of measured signals.
CCDF

1
/APD
∗
2
The CCDF trace displays the power variation probability on the
y-axis and power variation on the y-axis to confirm the CCDF and
APD of measured signals.
∗
1: CCDF (Complementary Cumulative Distribution Function)
∗
2: APD (Amplitude Probability Density)
Measurement Results
■
CCDF: The CCDF display indicates the cumulative
distribution of transient power variations
compared to average power.
■
APD: The APD display indicates the probability
distribution of transient power fluctuations
compared to average power.

Phase vs. Time
The Phase vs. Time trace displays a graph with phase on the y-axis
and time on the x-axis to confirm time variation of the measured
signal phase.
