R&S FSP Remote Control – Description of Commands
SENSe Subsystem
[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
Mode: A-F
[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
Mode: A-F
[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
Mode: A
This command is available from firmware version 1.40 or higher.
If the high-speed power measurement is switched off, the complete channel/adja-
cent channel power measurement is switched off.
