C/N
C/No
The C/N and C/No softkeys enable and disable the measurement of the
carrier/noise ratio, the
C/No measurement also being referred to a 1 Hz
bandwidth.
The maximum value of the current trace is determined when the function is
activated and is marked by means of the
REFERENCE FIXED marker.
Note: The measurement is performed on the trace where MARKER 1 is
located. To measure another trace, MARKER 1 has to be shifted to
the trace in question using the SELECT TRACE softkey in the MKR
menu.
If no marker is active, MARKER 1 is activated when the function is
switched on.
IEC/IEEE-bus command: CALC:MARK:FUNC:POW:SEL CN
CALC:MARK:FUNC:POW:RES? CN
CALC:MARK:FUNC:POW:SEL CN0
CALC:MARK:FUNC:POW:RES? CN0
CALC:MARK:FUNC:POW OFF
CHANNEL
BANDWIDTH
The CHANNEL BANDWIDTH softkey opens a window for selecting the
measurement channel bandwidth.
The default setting is 14 kHz.
The specified channel bandwidth allows the optimal setting of the measurement
parameters of the FSP using
ADJUST SETTINGS.
IEC/IEEE-bus command:
SENS:POW:ACH:BWID 14kHz
ADJUST
SETTINGS
The ADJUST SETTINGS softkey adapts the span to the channel bandwidth
selected.
For the carrier/noise ratio measurement, the span is set to:
4 x channel bandwidth + measurement margin
The adjustment is performed once; if necessary, the setting can be changed
later on.
IEC/IEEE-bus command:
SENS:POW:ACH:PRES CN | CN0
