R&S FSMR SENSe:SWEep Subsystem
1313.9723.12 6.1-195 E-1
[SENSe<1|2>:]SWEep:IF:SHIFt[:MODE] OFF | A | B | AUTO
Input signals at a frequency of half the 1
st
IF (in the frequency range of 2270 MHz to 2350 MHz) will
reduce the dynamic range of the analyzer. This problem only occurs for low RF attenuation values. It
can be overcome by shifting the 1
st IF
.
OFF: Normal operation .
A: For signals from 2270MHz to 2310 MHz .
B: For signals from 2310 MHz to 2350 MHz.
AUTO: Automatically selects the suitable 1
st IF
shifting.
The signal frequency has to specified with SWE:IF:SHIFT:FREQ.
The 1
st
IF shifting is automatically done for ACP measurements if center frequency ( =
signal frequency) is in the range of 2270 MHz … 2350 MHz. The IF SHIFT setting is
therefore ignored for ACP measurements.
Example:
"SENS:SWE:IF:SHIF A" '
activates IF SHIFT A
Characteristics: *RST value: OFF
SCPI: device-specific
[SENSe<1|2>:]SWEep:MODE AUTO | ESYNchroize | LIST
This command controls the sweep continuation.
AUTO
free running sweep
ESYNchronize external synchronization of sweep steps via the signal of the AUX PORTinterface
LIST Activates the spurious emissions measurement, the sweep list is defined using
the
SENS:LIST:RANGE
commands.
AUX-Port interface, requires option FSP-B10.
Example: "
SWE:MODE ESYNC
" 'enables external synchronization sweep mode.
Characteristics: *RST value: AUTO
SCPI: device-specific
[SENSe<1|2>:]SWEep:POINts 625, 1251, 1999, 2501,5001,10001,20001,30001
This command defines the number of measurement points for one sweep run.
Parameter: SENSe<1|2>]SWEep:POINts <numeric_value>
Characteristics: *RST value: 625
SCPI: conforming
