Model 2520 User’s Manual Getting Started 1-21
The main operation keys listed in Table 1-6 program these functions:
•
PW
— Sets laser diode current source (I
L
) pulse width.
•
DELAY
— Sets laser diode current source pulse delay.
•
COMPL
— Sets laser diode current source voltage compliance (limit).
These operating modes are covered in more detail in later sections of this manual.
Configuration menus
There are a number of configuration menus that can be accessed by pressing the CONFIG
key followed by the appropriate function or mode key. For example, you can configure the
measurement functions by pressing CONFIG then LASER V
L
, DETECTOR 1 I
PD
, or
DETECTOR 2 I
PD
. Configuration menus, which are summarized in Table 1-7 through
Table 1-9 , are available for the following operating modes:
• Measure and source functions (LASER and DETECTOR keys): Table 1-7 .
• TRIG and FILTER: Table 1-8 .
• SWEEP and MATH: Table 1-9 .
These various configuration menus are covered in detail in the pertinent sections of this
manual.
