CH FILTER
ON OFF
The CH FILTER ON/OFF softkey switches a modulation filter for the channel
power and adjacent channel power measurement on or off.
When selecting the digital mobile-radio standards NADC, TETRA and W-
CDMA 3 GPP (FWD and REV) using the ACP STANDARD softkey, the
softkey is automatically set to ON. When the other standards are selected,
weighting is not selectable and the softkey is not available.
CH FILTER ON The channel bandwidth is defined by the filter weighting
alone. Therefore, the CHANNEL BANDWIDTH softkey
cannot be operated.
The activated modulation filter influences the channel
and adjacent channel power measurement.
Within the definition range of the filter, the individual
pixels are weighted with the calculated filter attenuation
as a function of the spacing to the channel center. The
weighted display points are then added to the total
channel power.
CH FILTER OFF No modulation filter is switched on.

CHANNEL
BANDWIDTH
The CHANNEL BANDWIDTH softkey opens an entry window for setting the
channel bandwidth for the transmission channel and the corresponding
adjacent channels.
For all channels, the default setting is 14 kHz.

CHAN BANDWIDTH
CH 14 kHz
ADJ 14 kHz
ALT1 14 kHz
ALT2 14 kHz
Note:
If the bandwidth of one channel is changed, the new value is also
assigned to all subsequent channels in the table. The bandwidths
for the individual channels can be set independently, however, by
overwriting the table from the top to the bottom.
