4.2.1 Substitute Parameter Names
For
clarity in programming, the (Boolean) values of one and zero may also be represented by the appropriate
substitute parameter names, as shown
in Table 4.1.
SUBSTITUTE PARAMETER NAMES
I
SUBSTITUTE NAME VALUE
ON
1
OFF 0
OLD 1
NEW 0
TRUE 1
FALSE 0
Table 4.1 Substitute Parameter Names
The ON parameter name could be used in place of the 1 in the example in Section 4.2 as follows:
"TEC:DIS ON"
4.2.2 Compound Command Structure
Many of the LDC-3700 Series Laser Diode Controller remote commands require a compound structure. This is
done to distinguish between different commands of the same type and to designate which side of the LDC-3700
Series Laser Diode Controller the command is intended,
TEC (thermoelechic controller) or LAS (laser current
source).
The compound command structure is similar to a directory
path structure, as found in DOS. For example,
commands
which deal with the LDC-3700 Series Laser Diode Controller's TEC have the path "TEC:", as in the
command to set the TEC display to
measured resistance,
This structure is illustrated in Figure 4.2. Table 4.2 lists all of the LDC-3700 Series Laser Diode Controller's
devicedependent commands, with the
full path shown for each command and a brief explanation of its usage. For
more information,
see Section 4.4.
Section 4.4 presents a more detailed look at the LDC-3700 Series Laser Diode Controller devicedependent
commands, including
syntax diagrams, and example usage.
4.3 Common Commands
Another type of command is the "common command". These commands are common to instruments which support
the ANSI-IEEE-488.2 standard and are not necessarily reflected by front panel operations. Some of the common
commands are
useful for advanced programming techniques, such as generating senice requests. However,
common commands are not necessary for remote operation,
and the beginning programmer may chose to ignore
them entirely. The common commands
are documented in Chapter 3.
Two common
commands which are reflected by front panel operations are *SAV and *RCL. These commands
remotely perform the same operations
as when the SAVE and RECALL parameters are changed during Local
(front panel) operation.
