Product-Specific Commands—Description

Notes

No modulation is associated with a setpoint.

Therefore, a setpoint created in Normal or

Normal with Dither modulation mode will be

considered Normal (APC) mode. A setpoint

created in either HWS or On/Off modulation

mode will be in HWS (ACC) mode. In turn, a

setpoint in Normal mode can be used in Normal

or Normal with Dither mode. Also, a setpoint in

HWS mode can be used as well in On/Off

modulation mode. The mode must be supplied

because setpoints in Normal and HWS modes

may have the same name. Therefore, the

application will search for the specified setpoint

with the specified mode. If such a setpoint exists,

the application will adjust the wavelength,

power, current step, and temperature step

according to the setpoint. If the setpoint does not

exist, there will be no change.

Modes: If the instrument is in Normal or Normal

with Dither modes and the setpoint is in Normal

mode, there will be no change to the mode of

the instrument. If the setpoint is in HWS mode,

the application will go to HWS mode. If the

instrument is in HWS or On/Off mode and the

setpoint is in HWS mode, there will be no change

in mode. If the setpoint is in Normal mode, the

instrument will go to Normal mode.
