-110dBm to 20dBm 
-10dBm 
Explanation    When <value> is set in "Number" form (for example, 2), the default unit is dBm. 
When <value> is set in "Number + Unit" form (for example, 2dBm), the start 
level displayed in the interface of the RF signal generator is related to the setting 
of Level Unit.   
—  When the level unit is "dBm", 2.00dBm is displayed. 
—  When the level unit is "dBmV", 48.99dBmV is displayed. 
—  When the level unit is "dBuV", 108.99dBuV is displayed. 
—  When the level unit is "Volts", 281.50mV is displayed. 
—  When the level unit is "Watts", 1.58mW is displayed. 
  The default unit of the return value is dBm. 
  After the start level is set, you can rotate the knob to modify the start level at 
the current step. At this point, you can query or set the current step using the 
[:SOURce]:SWEep:STEP:STARt:LEVel:STEP command. 
Return Format  The query returns the start level of the sweep. For example, 2.00.
