Power Measurements – MEAS Key R&S FSL

C/No (span > 0)
Switches the measurement of the carrier/noise ratio with reference to a 1 Hz bandwidth on or
off. If no marker is active, marker 1 is activated.
The measurement is performed on the trace where marker 1 is located. To shift marker 1 and
measure another trace, use the Marker to Trace softkey in the marker menu. To determine the
maximum value of the current trace, use the Phase Noise/Ref Fixed softkey in the marker
menu.

Channel Bandwidth (span > 0)
Opens an edit dialog box to enter the measurement channel bandwidth. The default setting is 14
kHz.
Remote: POW:ACH:BWID 30kHz
Adjust Settings (span > 0)
Enables the RMS detector (see also "Detector overview" on page 4.42) and adjusts the span to
the selected channel bandwidth according to:
4 x channel bandwidth + measurement margin
The adjustment is performed once; if necessary, the setting can be changed later on.
Remote: POW:ACH:PRES CN | CN0
CP, ACP, MC–ACP
Activates the active channel or adjacent–channel power measurement either for a single carrier
signal or for several carrier signals, depending on the current measurement configuration, and
opens a submenu to configure the channel power measurement. With default settings the
measurement is performed by integrating the powers at the display points within the specified
channels (IBW method).
If multi–carrier ACP measurement is activated, the number of measured values is increased to
ensure that adjacent–channel powers are measured with adequate accuracy.

CP / ACP Standard
Opens an edit dialog box to select the settings according to predefined standards. For details on
the available standards see "Predefined CP / ACP standards" on page 4.79. By default no
standard is set.
