[:SOURce]:LEVel
Syntax [:SOURce]:LEVel <value>
[:SOURce]:LEVel?
Description Set the RF output amplitude.
Query the RF output amplitude.
Parameter Name Type Range Default
<value> Real -140dBm to 20dBm -140dBm
Explanation  When <value> is set in "Number" form, the default unit is dBm, for example,
2. In addition, <value> can also be set in "Number + Unit" form, for example,
2dBm. At this point, the amplitude displayed in the interface 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 RF amplitude is set, you can use the up/down direction keys or knob
to modify the amplitude at the current step. You can query or set the current
step using the [:SOURce]:LEVel:STEP command.
 When the amplitude offset is 0 dB, the amplitude displayed in the interface
(namely the setting amplitude) is equal to the actual output amplitude.
 When the amplitude offset is not 0 dB, the output amplitude is determined by
the setting amplitude and amplitude offset. The three parameters satisfy the
equation: setting amplitude (display amplitude) = output amplitude +
amplitude offset. You can use the [:SOURce]:LEVel:OFFSet command to query
and set the RF amplitude offset.
Return Format The query returns the RF amplitude, for example, 2.00.
Example :LEV 2dBm /*Set the RF amplitude to 2dBm*/
:LEV? /*Query the RF amplitude and the query returns 2.00*/
