To measure the power in zero span
1. Press the Time Domain Power softkey to activate the power measurement.
The corresponding submenu is displayed.
2. To limit the power evaluation range, switch on the limits (Limits On/Off softkey) and enter the limits
by using the Left Limit and Right Limit softkeys.
3. Select the type of power measurement by using the Mean or RMS softkey. (RMS or mean power),
the settings for max hold and averaging as well as the definition of limits.
4. To calculate and display the peak value, press the Peak softkey.
5. To calculate and display the standard deviation from the mean value, press the Std Dev softkey.
To set the channel configuration
1. Press the CP, ACP, MC–ACP softkey to active channel or adjacent–channel power measurement.
The corresponding submenu is displayed.
2. To use a predefined standard for measurement, press the CP / ACP Standard softkey (for details
on available standards see "Predefined CP / ACP standards" on page 4.79).
3. To configure the parameters independently of the predefined standards, press the CP / ACP
Config softkey (for details see "Settings of CP / ACP test parameters" on page 4.80).
4. To enter the sweep time, press the Sweep Time softkey.
