Command Syntax
7/01 LDC-3700 Series 43
CHAPTER 3
Command Tree Stucture
Many of the LDC−3700B remote commands require a compound structure. This is done to
distinguish between different commands of the same type and to designate the side of the LDC−
3700B the command is intended; TEC (thermoelectric controller) or LAS (laser current source). The
first mnemonic opens a path to a set of commands relating to that path. The second mnemonic then
defines the actual command.
The compound command structure is similar to a directory path structure, as found in DOS. For
example, commands which deal with the LDC−3700B TEC have the path "TEC:", as in the command
to set the TEC display to measured resistance,
TEC:DIS:R
This structure is illustrated in Figure 3.3. Table 4.1 on page 54 lists all of the LDC−3700B device−
dependent commands, with the full path shown for each command and a brief explanation of its
usage.
