[:SOURce]:LEVel:LIMit
Syntax [:SOURce]:LEVel:LIMit <value>
[:SOURce]:LEVel:LIMit?
Description Set the limit of the RF output amplitude.
Query the limit of the RF output amplitude.
Parameter Name Type Range Default
<value> Real -140dBm to 25dBm 25dBm
Explanation  When <value> is set in "Number" form (for example, 2), the default unit is
dBm. When it is set in "Number + Unit" form (for example, 2dBm), the limit
displayed in the RF signal generator interface is related to the setting of Level
Unit.
— When the level unit is "dBm", it is displayed as 2.00dBm;
— When the level unit is "dBmV", it is displayed as 48.99dBmV;
— When the level unit is "dBuV", it is displayed as 108.99dBuV;
— When the level unit is "Volts", it is displayed as 281.50mV;
— When the level unit is "Watts", it is displayed as 1.58mW.
 The default unit of all the return values is dBm.
 After setting the amplitude limit, you can use the up/down direction keys or
knob to modify the limit at the current step. At this point, you can query or set
the current step using the [:SOURce]:LEVel:LIMit:STEP command.
Return Format The query returns the limit of the RF output amplitude, for example, 5.60.
Example :LEV:LIM 5.6
