Channel Bandwidth
The Tx channel bandwidth is normally defined by the transmission standard.
The correct bandwidth is set automatically for the selected standard. The bandwidth for
each channel is indicated by a colored bar in the display.
The value entered for any Tx channel is automatically also defined for all subsequent
Tx channels. Thus, only enter one value if all Tx channels have the same bandwidth.
The value entered for any ADJ or ALT channel is automatically also defined for all
alternate (ALT) channels. Thus, only enter one value if all adjacent channels have the
same bandwidth.
Remote command:
[SENSe:]POWer:ACHannel:BANDwidth[:CHANnel<ch>]
[SENSe:]POWer:ACHannel:BANDwidth:ACHannel
[SENSe:]POWer:ACHannel:BANDwidth:ALTernate<ch>
Channel Spacings
Channel spacings are normally defined by the transmission standard but can be
changed.
If the spacings are not equal, the channel distribution in relation to the center frequency
is as follows:
Odd number of Tx channels
The middle Tx channel is centered to center frequency.
Even number of Tx channels
The two Tx channels in the middle are used to calculate the fre-
quency between those two channels. This frequency is aligned to
the center frequency.
