Syntax
:CALCulate:DBM:REFErence?
:CALCulate:DBM:REFErence { <range> |MIN|MAX|DEF}
Function
Sets the reference resistance for dBm operations in Ω.
The query returns an integer.
Explanation
 <range> is an integer ranging from 2 to 8000.
 The “DEF” is 600.
15. :CALCulate:LIMIt:STATe
Syntax
:CALCulate:LIMIt:STATe?
:CALCulate:LIMIt:STATe {ON|OFF|1|0}
Function
Turns on or off the Limit operation function.
The query returns ON or OFF.
Default
OFF
16. :CALCulate:LIMIt?
Syntax
:CALCulate:LIMIt?
Function
Queries the current Limit operation result.
The query returns PASS or FAIL.
Explanation
Limit operation function must be turned on before sending this
command.
17. :CALCulate:LIMIt:LOWEr
Syntax
:CALCulate:LIMIt:LOWEr?
:CALCulate:LIMIt:LOWEr { <range> |MIN|DEF}
Function
Sets the lower value for Limit operations.
The query returns the lower value of Limit operation in the form of
scientific notation.
Explanation
 The lower value should be lower than upper value, for more
details refer to :CALCulate:LIMIt:UPPEr.
