In the submenu measurement of amplitude probability density (APD) and comple-
mentary cumulative distribution (CCDF) can be selected alternately. Only one of the
signal statistic functions can be switched on at a time.
In default mode all statistic functions are switched off.
With a statistic function switched on the R&S ESU is set into zero span mode auto-
matically.
The R&S ESU measures the statistics of the signal applied to the RF input with the
resolution bandwidth set. In order not to influence the peak amplitudes the video
bandwidth is automatically set to 10 times the resolution bandwidth. The sample
detector is used for detecting the video voltage.
APD ON | OFF The APD ON/OFF softkey switches on or off the amplitude probability distribution
function. When the APD function is switched on, the CCDF function is switched off
automatically.
Remote command:
CCDF ON | OFF The CCDF ON/OFF softkey switches on or off the complementary cumulative distri-
bution function. When the CCDF function is switched on, the APD function is
switched off automatically.
