CHANNEL
SPACING
The CHANNEL SPACING softkey opens a table for defining the
channel spacings.
ACP CHANNEL SPACING
CHAN SPACING
ADJ 20 kHz
ALT1 40 kHz
ALT2 60 kHz
Since all the adjacent channels often have the same distance to
each other, the entry of the adjacent-channel spacing (ADJ)
causes channel spacing ALT1 to be set to twice and channel
spacing ALT2 to three times the adjacent-channel spacing. Thus
only one value needs to be entered in case of equal channel
spacing. The same holds true for the ALT2 channels when the
bandwidth of the ALT1 channel is entered.
Note: The channel spacings can be set separately by
overwriting the table from top to bottom.
The entry "TX" is only available for the multicarrier
ACP measurement.
IEC/IEEE-bus command: SENS:POW:ACH:SPAC:CHAN 20kHz

ACP REF
SETTINGS
The ACP REF SETTINGS softkey opens a table for selecting
the transmission channel to which the adjacent-channel relative
power values should be referenced.
ACP REFERENCE CHANNEL
TX CHANNEL 1
TX CHANNEL 2
TX CHANNEL 3
TX CHANNEL 4
MIN POWER TX CHANNEL
MAX POWER TX CHANNEL
LOWEST & HIGHEST CHANNEL
TX CHANNEL 1 - 4 Selection of one of channels 1 to 4.
MIN POWER
TX CHANNEL
The transmission channel with the
lowest power is used as a reference
channel.
MAX POWER
TX CHANNEL
The transmission channel with the
highest power is used as a reference
channel.
LOWEST & HIGHEST
CHANNEL
The outer lefthand transmission
channel is the reference channel for
the lower adjacent channels, the outer
righthand transmission channel that
for the upper adjacent channels.
