CALCulate<1|2>:LIMit<1...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: A
CALCulate<1|2>:LIMit<1...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).
The units DEG, RAD, S, HZ, PCT are not available.
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
