R&S FSP Remote Control – Description of Commands
SENSe Subsystem
6.194 Operating Manual 1164.4556.12 - 06
[SENSe<1|2>:]POWer:ACHannel:PRESet:RLEVel
This command adapts the reference level to the measured channel power and – if required - switches
on previously the adjacent channel power measurement. This ensures that the signal path of the
instrument is not overloaded. Since the measurement bandwidth is significantly smaller than the signal
bandwidth in channel power measurements, the signal path can be overloaded although the trace is
still significantly below the reference level. If the measured channel power equals the reference level,
the signal path is not overloaded.
The command is only available in the frequency domain (span > 0).
Example:
"POW:ACH:PRES:RLEV;*WAI"
'Adapts the reference level to the measured channel power.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A-F
[SENSe<1|2>:]POWer:ACHannel:PRESet:RLEVel:OFFSet 0 … 100 dB
This command allows to modify the ADJUST REF LEVEL function for user standards. It defines an
additional level offset to be taken into account for the analyzer's reference level setting. It is only
available if Fast ACP is not active and no predefine standard is selected.
Example: "POW:ACH:PRES:RLEV:OFFS 10dB"
'set the level adjust offset to 10dB
Characteristics: *RST value: 0 dB
SCPI: device-specific
Mode: A
[SENSe<1|2>:]POWer:ACHannel:REFerence:AUTO ONCE
This command sets the reference value for the relative measurement to the currently measured
channel power.
The command is only available in the frequency domain (span > 0).
Example:
"POW:ACH:REF:AUTO ONCE"
Characteristics: *RST value: -
SCPI: device-specific
Mode: A-F
This command is an event and therefore has no *RST value and no query.
Subsequent commands have to be synchronized with
*WAI
,
*OPC
or
*OPC?
to the
end of the auto range process which would otherwise be aborted.
