R&S FSP Remote Control – Description of Commands
CALCulate Subsystem
6.5.5.4 CALCulate:LIMit:LOWer Subsystem
The CALCulate:LIMit:LOWer subsystem defines the lower limit line.
CALCulate<1|2>:LIMit<1...8>:LOWer[:DATA] <numeric_value>,<numeric_value>...
This command defines the values for the selected lower limit line.
Up to 8 limit lines can be defined at the same time. This command is independent of the measurement
window.
The number of values for the CONTrol axis and for the corresponding LOWer limit line has to be
identical. Otherwise default values are entered for missing values or not necessary values are deleted.
The unit must be identical with the unit selected by
CALC:LIM:UNIT
. If no unit is indicated, the unit
defined with
CALC:LIM:UNIT
is automatically used.
If the measured values are smaller than the LOWer limit line, the limit check signals errors.
In analyzer mode, the units DEG, RAD, S, HZ, PCT are not available.
Example:
"CALC:LIM2:LOW -30,-40,-10,-40,-30"
'Defines 5 lower limit values for limit line 2 in the preset unit.
"CALC:LIM2:LOW?"
'Outputs the lower limit values of limit line 2 separated by a comma.
Characteristics: *RST value: - (LIMit:STATe is set to OFF)
SCPI: conform
Mode: A
CALCulate<1|2>:LIMit<1...8>:LOWer:MARGin <numeric_value>
This command defines a margin to a lower limit line, at which out-of-limit values are signaled (if the
limit check is active), but not handled as a violation of the limit value. The margin is independent of the
measurement window.
Example:
"CALC:LIM:LOW:MARG 10dB"
Characteristics: *RST value: 0
SCPI: device-specific
Mode: A
CALCulate<1|2>:LIMit<1...8>:LOWer:MODE RELative | ABSolute
This command selects the relative or absolute scaling for the y-axis of the selected lower limit line.
The setting is independent of the measurement window.
Selecting RELative causes the unit to be switched to DB.
Example:
"CALC:LIM:LOW:MODE REL"
'Defines the y-axis of limit line 2 as relative scaled.
Characteristics: *RST value: ABSolute
SCPI: device-specific
Mode: A
