MODE Area Description
The MODE area allows you to access and change the parameters that you want to
configure.
It consists of 8 keys that light up when the corresponding function is active.
Function Keys
Key Description
λ .f Edits the current value of the emission wavelength λ or the optical
frequency f ., and enables the entry of a new value (see section Changing the
Emission Wavelength or Frequency, p. 27 ).
P • Edits the current value of the output power P , and allows the entry of a
new value (see section Changing the Optical Output Power and Diode
Current, p. 33 ).
• Switches to the constant-power mode (see section Switching Between
Constant-Power and Constant-Current Modes, p. 34)
.
I • Edits the current value of the diode current I , and allows the entry of a
new value.
• Switches to the constant-current mode (see section Switching Between
Constant-Power and Constant-Current Modes, p. 34 ).
STEP Changes the wavelength increment (STEP) value (see section Setting a
Predefined Increment/Decrement Step, p. 28 ).
It is also possible to increase or decrease the wavelength STEP-by-STEP, at
any time, by pressing the
←
or
→
keys on the keypad.
APC Automatic Power Control. Switches between constant-current (APC light
off) and constant-power (APC light on) modes.
See section
Switching Between Constant-Power and Constant-Current
Modes, p. 34 .
FSC Enables/Disables the Fine SCanning mode. (see section Using the Fine
Scanning Mode (Fine Tuning), p. 28 ).
2nd Enables you to access advanced functions.
λ .f To set the motor-speed for swept-mode wavelength scanning
(see section
Setting the Sweep Speed, p. 32) .
P To perform power calibration (see section Performing Power
Calibration, p. 37 ) .
I To perform system auto-calibration (see section Performing
Internal Wavelength Referencing, p. 38) .
APC To disable/enable active cavity control (see section Disabling/
Enabling Active Cavity Control, p. 35 ).
dBm/mW To turn on active wavelength monitoring (see section Enabling
Active Wavelength Monitoring, p. 39 ) .
