CCDF - Complimentary Cumulative Distribution Function
The Complementary Cumulative Distribution Function (CCDF) represents the probability that the peak
power above average power of a measured signal exceeds a threshold.
CCDF is a plot of the percent of time that a signal’s power value exceeds it average value versus the
amount by which it exceeds the average. The CCDF plot has a log of probability on the Y-axis (100% at
the top) and dB above average amplitude on the X-axis (0 at the left).
CDMA
Acronym for Code Division Multiple Access.
Center Frequency
The frequency corresponding to the center of a frequency span of the analyzer display.
Check Mark Indicator
The check mark indicator in the upper-left corner of the display indicates the display for which the
acquisition hardware is optimized. When you have more than one display open, the display with the
check mark indicator has control over the acquisition hardware. To give a display priority over any
others, click its title bar.
CISPR
International special committee on radio interference. (Comité international spécial des perturbations
radioélectriques)
CW
Acronym for Continuous Wave.
