CALCulate<1|2>:LIMit<1 to 8>:LOWer:SHIFt <numeric_value>
This command shifts a limit line by the indicated value in Y direction. In contrast to
CALC:LIM:LOW:OFFS, the line is shifted by modifying the individual Y values but not by means of an
additive offset. The shift is independent of the measurement window.
Example: "CALC:LIM3:LOW:SHIF 20DB" 'Shifts all Y values of limit line 3 by 20 dB.
Characteristics: *RST value: --
SCPI: device-specific
Mode: A, FM
This command is an event and therefore has no *RST value and no query.
CALCulate<1|2>:LIMit<1 to 8>:LOWer:SPACing LINear | LOGarithmic
This command selects linear or logarithmic interpolation for the lower limit line.
Example: "CALC:LIM:LOW:SPAC LIN"
Characteristics: *RST value: LIN
SCPI: device-specific
Mode: R, A
CALCulate<1|2>:LIMit<1 to 8>:LOWer:THReshold <numeric_value>
This command defines an absolute threshold value for limit lines with relative Y axis scaling
independently of the measurement window. The absolute threshold value is used in the limit check
as soon as it exceeds the relative limit value.
The unit must correspond to the unit selected with CALC:LIM:UNIT (except dB which is not
allowed). If no unit is indicated, the unit defined with CALC:LIM:UNIT is automatically used
(exception: dBm instead of dB).
Example: "CALC:LIM2:LOW:THR -35DBM" 'Defines an absolute threshold value
'for limit line 2.
Characteristics: *RST value: -200 dBm
SCPI: device-specific
Mode: A, FM
