6.4.3 ABORT SUBSYSTEM
This subsystem cancels any pending trigger levels previously stored and resets them to the
immediate value. ABORt also resets the WTG bit in the Operation Condition register. ABORt is
executed upon initial power-up of the power supply.
6.4.4 LIST SUBSYSTEM
The LIST subsystem is represented by the 100 memory locations (groups of settings) which are
stored in the volatile memory. Each setting contains values for: Current, Voltage, Dwell, and
Relay. The range for the first two values is constrained by the virtual model and protection limit
settings. The range for the dwell time is between 0.01 and 655.36 seconds. If the relay is config-
ured to LIST using the UTIL menu on the front panel, it can be set to 1 (on, energized) or 0 (off,
de-energized). Even when the relay is not configured to run a list, LIST:CONT (either 0 or 1)
must be executed once, otherwise the list will not execute.
6.4.5 MEASURE SUBSYSTEM
This query subsystem returns the voltage and current measured at the power supply's output
terminals.
6.4.6 OUTPUT SUBSYSTEM
This subsystem controls the power supply's output state: on or off.
6.4.7 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.
6.4.8 STORAGE SUBSYSTEM
The KLP has 40 memory locations where the current state of the power supply can be stored
and then recalled. The storage system saves five settings, Voltage, Current, Voltage protection
level, Current protection level and output on/off state. The advantage to using these 40 locations
instead of sending five commands is processing time. The Saved data is binary data and
requires no processing before applying it to the output, thereby reducing the time needed to
change from one state to another to less a millisecond. The *SAV command saves the five
power supply setting to a location. The *RCL command recalls the fives settings from a location
and applies them it to the power supply output. The MEM:LOC command allows the data to be
loaded into a location without actually programming the KLP. The MEM:LOC? query allows the
five settings to be retrieved prior to applying them to the output, providing a method of verifying
that the settings are correct before applying them to a unit under test.
6.4.9 SYSTEM SUBSYSTEM
This subsystem controls the RS 232 port, GPIB address, passwords, security, language, key-
board lockout, and compatibility with older Kepco equipment.
6.4.10 [SOURCE:]VOLTAGE AND [SOURCE:]CURRENT SUBSYSTEMS
These subsystems program the output voltage and current of the power supply.
