6.5.5.5 CALCulate:LIMit:UPPer Subsystem
The CALCulate:LIMit:UPPer subsystem defines the upper limit line.
CALCulate<1|2>:LIMit<1...8>:UPPer[:DATA] <numeric_value>,<numeric_value>...
This command defines the values for the upper limit lines.
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 UPPer and/or LOWer limit line
have 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.
In analyzer mode, the units DEG, RAD, S, HZ, PCT are not available.
In analyzer mode, the limit check signals errors if the measured values exceed the UPPer limit line.
Example:
"CALC:LIM2:UPP -10,0,0,-10,-5"
'Defines 5 upper limit values for limit line 2 in the preset unit.
"CALC:LIM2:UPP?"
'Outputs the upper limit values for 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>:UPPer:MARGin <numeric_value>
This command defines a margin to an upper 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:LIM2:UPP:MARG 10dB"
'Defines the margin of limit line 2 to 10 dB below the limit value.
Characteristics: *RST value: 0
SCPI: device-specific
Mode: A
CALCulate<1|2>:LIMit<1...8>:UPPer:MODE RELative | ABSolute
This command selects the relative or absolute scaling for the y-axis of the selected upper limit line. The
setting is independent of the measurement window.
Selecting RELative causes the unit to be switched to DB.
Example:
"CALC:LIM2:UPP:MODE REL"
'Defines the y-axis of limit line 2 as relative scaled.
Characteristics: *RST value: ABSolute
SCPI: device-specific
Mode: A
