The remote commands required to perform these tasks are described in Chap-
ter 11.6.9, "Analyzing Statistics (APD, CCDF)", on page 701.
Both dialog boxes are identical except for the "Percent Marker" setting, which is only
available for CCDF measurements.
Percent Marker (CCDF only).......................................................................................217
Analysis Bandwidth.....................................................................................................217
Number of Samples.................................................................................................... 218
Gated Trigger.............................................................................................................. 218
Edit Gate Ranges........................................................................................................218
Adjust Settings............................................................................................................ 218
Percent Marker (CCDF only)
Defines a probability value. Thus, the power which is exceeded with a given probability
can be determined very easily. If marker 1 is deactivated, it is switched on automati-
cally.
Remote command:
CALCulate<n>:MARKer<m>:Y:PERCent on page 702
Analysis Bandwidth
Defines the analysis bandwidth.
For correct measurement of the signal statistics, the analysis bandwidth has to be
wider than the signal bandwidth in order to measure the peaks of the signal amplitude
correctly. To avoid influencing the peak amplitudes, the video bandwidth is automati-
cally set to 10 MHz. The sample detector is used for detecting the video voltage.
The calculated measurement time is displayed for reference only.
Remote command:
[SENSe:]BANDwidth[:RESolution] on page 769
