A list of all of the IEEE 488.2 Common Commands supported by the LDC−3908 follows.
The IEEE 488.2 common commands and LDC−3908 mainframe commands are documented in
Chapter 4, Command Reference.
LDC-3908 Mainframe Specific Commands
The LDC-3908's command set can be divided into three categories: 1) IEEE 488.2 common
commands, 2) LDC-3908 mainframe commands, and 3) module-dependent commands. The IEEE
488.2 common commands and LDC-3908 mainframe commands are documented in this manual.
The commands which apply to each module are found in that module's instruction manual.
Status Reporting
This section contains information for understanding instrument error and status reporting. It also
contains information regarding the use of the instrument status for generating interrupts for
interrupt-driven programs or subroutines. Understanding the Operation Complete definition for the
instrument is useful for programming synchronization. The Output Off Register section also
contains information about setting some of the conditions that force the laser current source and/or
TEC output to turn off.
The following sections describe the Event and Condition registers, Operation Complete flag, Output
Off registers, and Error Messages.
Event and Condition Registers
In addition to the required IEEE 488.2 status reporting structures, the LDC−3908 remote interface
provides Event and Condition registers for module operations. The ALLEVE register is used to
report events that occur during the operation of the LDC−3908 and that are enabled to be passed to
the status byte. The ALLEVE register contains summary bits from each of the sixteen modules.
Likewise, the ALLCOND register is used to report conditions which occur during the operation of the
LDC−3908, and are enabled to be passed on to the status byte. The ALLCOND register contains
summary bits from each of the sixteen modules.
The bits in the ALLCOND and ALLEVE registers are logically ORed to form a summary message in
the status byte for that particular register.
Events are different from conditions. Events signal one−time occurrences and are not reset until
either the corresponding module’s Event Register(s) is queried, the *CLS command is issued, or the
LDC−3908 is powered off. Conditions reflect the current state of the device and therefore may
change many times during operation.
