Command Syntax Description
Get Laser Status LASer:SETpoint?
When the following conditions are all true, a 1 is returned
and a steady green dot shows in the laser field of the
instrument’s touchscreen. Otherwise, a 0 is returned.
The hardware key switch interlock on the front
panel is in the “on” position.
The instrument’s microcontroller, in response to
remote or touchscreen control, has commanded
the laser to power on.
The laser’s currently active dither state (on or off)
matches the last requested dither state.
The laser’s currently active ITU channel matches
the last requested ITU channel.
The laser currently reports it is in the “ready” state.
The laser currently reports it is in the “enabled”
state.
The laser currently reports its optical output power
is greater than 12.0 dBm.

Power in dBm
LASer:TAP:DBM?
Returns a floating point value with units of dBm. This is a
measurement of the optical output power measured
downstream from the laser module using an optical tap.
The value returned by LAS:OOP? is a measurement made
by a photodiode integrated into the laser module. The two
measurements may differ slightly. Optical output power will

LASer:TAP:MW?
Returns a floating point value with units of mW, with the
measurement details identical to those described for
LAS:TAP:DBM?.
Get Nominal
Laser Wavelength
LASer:WAVE_NOMinal?
Returns a positive integer for the calculated wavelength,
generated from the nominal frequency of the ITU channel,
with the current fine-tuning frequency offset added or
subtracted. The value is in units of 10 fm (femtometers).
This is the same value that is displayed on the LCD GUI
laser settings page. Note that it is derived from the
requested frequency and does not represent a live
