In the submenu measurement of amplitude probability density (APD) and complementary
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 FSQ is set into zero span mode automatically.
The R&S FSQ 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: CALC:STAT:APD ON
CCDF (ON OFF) The CCDF (ON OFF) softkey switches on or off the complementary cumulative distribution
function. When the CCDF function is switched on, the APD function is
switched off automatically.
Remote command: CALC:STAT:CCDF ON
