6.16.6 SENSe:ESPectrum Subsystem
This chapter describes all remote control commands available to configure Spectrum Emission Mask
measurements.
[SENSe<1|2>:]ESPectrum:BWIDth numeric_value
This command defines the bandwidth used for measuring the channel power in the Spectrum Emission
Mask measurement. Allowed range: 20 Hz …span of reference range.
The numeric suffix at SENSe<1|2> is irrelevant.
Example:
"ESP:BWID 3.84MHz"
'sets the channel bandwidth to 3.84MHz
Characteristics: *RST value: 3.84 MHz
SCPI: device-specific
Mode: A
[SENSe<1|2>:]ESPectrum:FILTer:RRC[:STATe] ON | OFF
This command activates or deactivates the use of a RRC filter for measuring the channel power in the
Spectrum Emission Mask measurement.
The numeric suffix at SENSe<1|2> is irrelevant.
Example:
"ESP:FILT:RRC ON"
'RRC filter switched on
Characteristics: *RST value: ON
SCPI: device-specific
Mode: A
[SENSe<1|2>:]ESPectrum:FILTer:RRC:ALPHa 0…1
This command sets the alpha value of the RRC filter for measuring the channel power in the Spectrum
Emission Mask measurement if the RRC filter is switched on.
The numeric suffix at SENSe<1|2> is irrelevant.
Example:
"ESP:FILT:RRC:ALPH ON"
'RRC filter switched on
Characteristics: *RST value: 0.22
SCPI: device-specific
Mode: A
[SENSe<1|2>:]ESPectrum:PRESet[:STANdard] 'xml_file'
This command selects the specified XML file under D:\r_s\instr\sem_std . If the file is stored in a
subdirectory, include the relative path.
The query returns information about the selected standard, the power class and the link direction. If no
standard has been selected, the query returns ''.
The numeric suffix at SENSe<1|2> is irrelevant.
