[
SENSe<1|2>:]POWer:ACHannel:BANDwidth|BWIDth:ALTernate<1...11>
This command defines the channel bandwidth of the alternate adjacent channels of the radio
transmission system. If the channel bandwidth of alternate adjacent channel 1 is changed, the
bandwidth of alternate adjacent channels 2 to 11 is automatically set to the same value.
With [SENSe<1|2>:]POWer:HSPeed set to ON, steep–edged channel filters are available.
For further information on filters refer to chapter "Instrument Functions", section "List of
available RRC and channel filters".
Parameter
100 Hz to 1000 MHz
Example
POW:ACH:BWID:ALT2 30kHz
Characteristics
*RST value: 14 kHz
SCPI: device–specific
Mode
A–F
[SENSe<1|2>:]POWer:ACHannel:MODE
This command switches between absolute and relative adjacent channel measurement. The
command is only available with span > 0 and if the number of adjacent channel is greater than 0.
The numeric suffixes <1|2> are not relevant.
This command is available from firmware version 1.10.
Parameter
ABSolute | RELative
Example
POW:ACH:MODE REL
Sets the adjacent channel measurement mode to relative.
Characteristics
RST value: RELative
SCPI: device–specific
Mode
A–F
[SENSe<1|2>:]POWer:ACHannel:PRESet
This command adjusts the frequency span, the measurement bandwidths and the detector as
required for the number of channels, the channel bandwidths and the channel spacings selected
in the active power measurement. If necessary, adjacent–channel power measurement is
switched on prior to the adjustment.
To obtain correct results, a complete sweep with synchronization to the end of the sweep must
be performed after the adjustment. Synchronization is possible only in the single sweep mode.
The result is queried with the CALCulate<1|2>:MARKer:FUNCtion:POWer:RESult?
command.
The numeric suffixes <1|2> are not relevant.
