R&S FSMR SENSe:POWer Subsystem
1313.9723.12 6.1-189 E-1
[SENSe<1|2>:]POWer:ACHannel:TXCHannel:COUNt 1 to 12
This command selects the number of carrier signals.
The command is available only for multicarrier channel and adjacent-channel power measurements
(
CALC:MARK:FUNC:POW:SEL MCAC
) in the frequency domain (span > 0).
Example:
"POW:ACH:TXCH:COUN 3"
Characteristics: *RST value: 4
SCPI: device-specific
[SENSe<1|2>:]POWer:BANDwidth|BWIDth 10 to 99.9PCT
This command defines the percentage of the power with respect to the total power. This value is the
basis for the occupied bandwidth measurement (command:
POWer:ACHannel:PRESet OBW
).
The command is only available in the frequency domain (span > 0).
Example:
"POW:BWID 95PCT"
Characteristics: *RST value: 99PCT
SCPI: device-specific
[SENSe<1|2>:]POWer:HSPeed ON | OFF
This command switches on or off the high-speed channel/adjacent channel power measurement.
The measurement itself is performed in the time domain on the center frequencies of the individual
channels. The command automatically switches to the time domain and back.
Depending on the selected mobile radio standard, weighting filters with cos characteristic or very
steep-sided channel filters are used for band limitation.
The command is only available in the frequency domain (span > 0).
Example:
"POW:HSP ON"
Characteristics: *RST value: OFF
SCPI: device-specific
[SENSe<1|2>:]POWer:NCORrection ON | OFF
This command switches on or off the correction of the instrument inherent noise for channel power
measurement. On activating this function, a reference measurement of the instrument inherent noise
is performed. The measured noise power is then subtracted from the power in the examined
channel.
The instrument inherent noise is then re-determined after any change of the center frequency,
resolution bandwidth, sweep time and level setting by repeating the reference measurement in the
new instrument setting.
Example:
"POW:NCOR ON"
Characteristics: *RST value: OFF
SCPI: device-specific
[SENSe<1|2>:]POWer:TRACe 1 to 3
This command assigns the channel/adjacent channel power measurement to the indicated trace in
the selected measurement window. The corresponding trace must be active, i.e. its state must be
different from blank.
The measurement of the occupied bandwidth (OBW) is performed on the trace on which marker 1 is
positioned. To evaluate another trace, marker 1 must be positioned to another trace with
CALCulate:MARKer:TRACe
.
Example: "
POW:TRAC 2"
'Assigns the measurement in screen A to trace 2.
"
SENS2:POW:TRAC 3"
'Assigns the measurement in screen B to trace 3.
Characteristics: *RST value: -
