subsystem commands used in the ATE-DMG Power Supply with the “root” at the left side, and
specific commands forming the branches. The following paragraphs introduce the subsystems;
subsystem commands are defined and explained in Appendix B.
3.7.3.1 ABORT SUBSYSTEM
This subsystem allows pending trigger levels to be cancelled.
3.7.3.2 DIAG SUBSYSTEM
This subsystem is used to enable/disable external analog control of the output.
3.7.3.3 DISPLAY SUBSYSTEM
This subsystem controls the second line of the LCD. The first line will always display the LOCal
or REMote operation status and the constant Voltage (CV) or constant Current functioning mode
(CC).
3.7.3.4 INITIATE SUBSYSTEM
This subsystem enables the trigger system. When a trigger is enabled, the triggering action will
occur upon receipt of a GPIB <GET>, *TRG or TRIGger command. If a trigger circuit is not
enabled, all trigger commands are ignored.
3.7.3.5 LIST SUBSYSTEM
The LIST subsystem is represented by the 40 memory locations (groups of settings) which are
stored in the nonvolatile memory. Each setting contains values for: Current, Voltage, Overcur-
rent, Overvoltage, Next memory location, and Time. The range for the first four values is the
maximum available range for the specific power supply. The Next memory location is the
address of the next group of settings and is between 1 and 40. A value of 0 means end of chain.
The Time setting is between 0.01 and 300 seconds. In order to access one of the 40 memory
locations an index value must be provided. The 40 memory locations can be very useful in
remote mode using the *RCL command (see Appendix A, PAR. A.10.)
3.7.3.6 MEASURE SUBSYSTEM
This query subsystem returns the voltage and current measured at the power supply's output
terminals.
3.7.3.7 OUTPUT SUBSYSTEM
This subsystem controls the power supply's voltage and current outputs
3.7.3.8 PROTECTION SUBSYSTEM
This subsystem allows overvoltage/overcurrent protection tripping to be delayed to prevent brief
transients (caused by application of power to a reactive load) from tripping overvoltage/overcur-
rent protection.
3.7.3.9 STATUS SUBSYSTEM
This subsystem programs the power supply status register. The power supply has two groups of
status registers: Operation and Questionable. Each group consists of three registers: Condition,
Enable, and Event.
