# of Samples ← APD
Opens an edit dialog box to set the number of power measurements that are taken into
account for the statistics.
Apart from the number of measurements the overall measurement time depends also
on the set resolution bandwidth as the resolution bandwidth directly influences the
sampling rate.
For details see "Selecting the number of samples" on page 313.
Remote command:
CALCulate<n>:STATistics:NSAMples
on page 793
Scaling ← APD
Opens a submenu to change the scaling parameters of x- and y-axis.
x-Axis Ref Level ← Scaling ← APD
Opens an edit dialog box to enter the reference level in the currently active unit (dBm,
dBµV, etc). The function of this softkey is identical to the "Ref Level" softkey in the
"Amplitude" menu (see
"Ref Level" on page 352).
For the APD function this value is mapped to the right diagram border. For the CCDF
function there is no direct representation of this value on the diagram as the x-axis is
scaled relatively to the measured mean power.

x-Axis Range ← Scaling ← APD
Opens the "Range" submenu to select a value for the level range to be covered by the
statistics measurement selected.
