C/N

Switches the measurement of the carrier/noise ratio on or off. If no marker is active,
marker 1 is activated.

The measurement is performed on the trace that marker 1 is assigned to. To shift
marker 1 and measure another trace, use the "Marker To Trace" softkey in the
"Marker" menu (see 

" Assigning the Marker to a Trace "

 

on page 427).

C/N0

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 that marker 1 is assigned to. To shift
marker 1 and measure another trace, use the "Marker To Trace" softkey in the
"Marker" menu (see

Channel Bandwidth

Defines the channel bandwidth.

The default setting is 14 kHz.

Remote command: 

[SENSe:]POWer:ACHannel:BANDwidth[:CHANnel<ch>]

 

on page 545

Adjust Settings

Enables the RMS detector and adjusts the span to the selected channel bandwidth
according to:

"4 x channel ban measurement margin"

The adjustment is performed once; if necessary, the setting can be changed later on.

Remote command: 

[SENSe:]POWer:ACHannel:PRESet
