Configuring sources
Follow the general procedures below to set source and compliance values for the laser
diode current source as well as bias voltage values for the two photodiode sources.
Editing source values
Use the following keys to edit source values:
•
LASER IL, DETECTOR 1 VB, and DETECTOR 2 VB
— selects the laser
diode, photodiode #1, or photodiode #2 source for editing.
•
EDIT
— edits the last selected source. A blinking cursor will appear in the field to
be edited, and the EDIT annunciator will turn on while in the edit mode. If no key
is pressed within a few seconds, the edit mode will be cancelled automatically.
•
COMPL
— allows editing of the laser diode current source voltage compliance.
•
EDIT
and
— places the display cursor on the display digit to be changed.
•
EDIT
▲
or
▼
— increments or decrements the source value. Note that pressing
either of these keys will automatically enable the source edit mode.
•
RANGE
▲
or
▼
— selects the laser diode source range (500mA or 5A) while in
edit mode.
•
ENTER
— Completes source editing without waiting for time-out period.
•
Numeric keys (0-9
) — allow you to directly enter source values.
•
EXIT
— exits the edit mode without waiting for the time-out period.
