The LASer:REFerence? query returns the reference power in the units of the present display mode.
None.
The response data is the reference power in the units of the present display mode.
This command has the same effect as manually switching to the dB scale, adjusting the display to
0.000 dB, switching to the mW or dBm scale and viewing the display.
"LAS:REF?" response: 0.5000, indicates the reference power is 0.5 mW.
"LAS:REFERENCE?" response: 0.0000, indicates the reference power is 0 dBm.
The LASer:STEP command sets the power step size which is used with the increment and
decrement commands.
The <nrf value> represents the step size power.
Linear Scale: .0001 to +1.0000 milliwatts
Log Scale: .0001 to 1.000 dBm
UW microwatts
MW milliwatts
W watts
DB decibels
The linear (mW) step and the log (dB) step are held in separate registers. When the increment or
decrement command is issued the display units determine which step size register is used.
If the optional <suffix> is not used, MW is assumed.
The step size can be set with the output on or off.
"LAS:STEP 0.500"action: Sets the step size to 0.5 milliwatts.
"LAS:STEP 0.01 DB"action: Sets the step size to 0.01 dB.
