R&S FSL SENSe Subsystem
1300.2519.12 6.225 E-11
Characteristics
*RST value: 1
SCPI: device–specific
Mode
A–F
[SENSe<1|2>:]POWer:ACHannel:SPACing[:ACHannel]
This command defines the spacing between the carrier signal and the adjacent channel (ADJ).
The modification of the adjacent–channel spacing (ADJ) causes a change in all higher
adjacent–channel spacings (ALT1, ALT2, ...): they are all multiplied by the same factor (new
spacing value / old spacing value).
The numeric suffixes <1|2> are not relevant.
Parameter
100 Hz to 2000 MHz
Example
POW:ACH:SPAC 33kHz
Sets the spacing between the carrier signal and the adjacent channel to 33 kHz, the alternate
adjacent channel 1 to 66 kHz, the alternate adjacent channel 2 to 99 kHz, and so on.
Characteristics
*RST value: 14 kHz
SCPI: device–specific
Mode
A–F
[SENSe<1|2>:]POWer:ACHannel:SPACing:ALTernate<1...11>
This command defines the spacing between the alternate adjacent channels and the TX
channel (ALT1, ALT2, ...). A modification of a higher adjacent–channel spacing causes a
change by the same factor (new spacing value / old spacing value) in all higher adjacent–
channel spacings, while the lower adjacent–channel spacings remain unchanged.
The numeric suffixes <1...11> defines the alternate adjacent channel. The numeric suffixes
<1|2> are not relevant.
Parameter
100 Hz to 2000 MHz
Example
POW:ACH:SPAC:ALT1 100kHz
Sets the spacing between TX channel and alternate adjacent channel 1 (ALT1) from 40 kHz to
100 kHz. In consequence, the spacing between the TX channel and all higher alternate adjacent
channels is increased by the factor 100/40 = 2.5: ALT2 = 150 kHz, ALT3 = 200 kHz, ALT4 = 250
kHz.
Characteristics
*RST value: 40 kHz (ALT1), 60 kHz (ALT2), 80 kHz (ALT3), ...
