LAS:ALL:CALMD? NONE Returns all the channels' CAL PD (monitor responsivity)
constants.
LAS:ALL:LDI 4 User to set all the channels' constant current mode set
point values.
LAS:ALL:LDI? NONE Used to return all the channels' constant current source
measured values (measured about every 600 mS).
LAS:ALL:LDV? NONE Used to return all the channels' measured laser voltage
values (measured about every 600 mS).
LAS:ALL:LIM:I 4 Used to set all the channels' LASER constant current
source limit values.
LAS:ALL:LIM:I? NONE Used to return all the channels' LASER constant
current source limit values.
LAS:ALL:LIM:P 4 Used to set all the channels' constant optical power
(from monitor PD) limit values.
LAS:ALL:LIM:P? NONE Used to return all the channels' optical power (from
monitor PD) limit values.
LAS:ALL:MDI 4 Used to set all the channels' constant optical power set
points, if PD responsivity is 0.
LAS:ALL:MDI? NONE Used to return all the channels' monitor PD current
measured values (measured about every 600 mSec.)
LAS:ALL:MDP 4 Used to set all the channels' constant optical power set
points, if PD responsivity is non-zero.
LAS:ALL:MDP? NONE Returns all the channels' actual monitor PD power
values (measured about every 600 mSec.).
LAS:ALL:MODE? NONE Returns all the channels' LAS operating modes.
LAS:ALL:MODE:IHB
W
NONE Sets all the LAS channels to constant current, high
bandwidth mode.
LAS:ALL:MODE:ILB
W
NONE Sets all the LAS channels to constant current, low
bandwidth mode.
LAS:ALL:MODE:MDP NONE Sets all the LAS channels to constant power mode.
LAS:ALL:ONLY:OUT 4 Set all the channels' LAS output (only) on or off. Useful
with combination modules.
LAS:ALL:OUT 4 Same action as setting all the LAS channel's OUTPUT
switches on/off.
LAS:ALL:OUT? NONE Returns the OUTPUT switch status for all the LAS
channels.
LAS:CALMD 1 Used to set the present channel's CAL PD (monitor
responsivity) constant.
LAS:CALMD? NONE Returns the present channel's CAL PD (monitor
responsivity) constant.
LAS:CAL:LDI NONE Used to enter current calibration mode on the present
LAS channel.
LAS:CAL:LDI? NONE Returns the ready state for entering a constant I
calibration value on the present LAS channel.
LAS:CAL:LDV NONE Used to enter the laser voltage calibration mode on the
present LAS channel.
