Table C-5. Bit Configuration of Status Reister Groups

Meaning

Operation Status Group

The interface is waiting for a trigger

The power supply is in the positive constant-voltage mode

The power supply is sourcing current in the constant-current mode

Questionable Status Group

The power supply overvoltage protection circuit has tripped The power supply overcurrent protection circuit has tripped The power supply has an overtemperature condition

The power supply remote inhibit status is active The power supply output is unregulated

Standard Event Status Group

Operation complete

Query error

Device-dependent error

Execution error

Command error

Power on

Status Byte and Service Request Enable Registers

Questionable status byte summary

Message available

Event status byte summary

Master status summary

Request for service

Operation status byte summary

Status Programming Examples. Table C-3 shows four examples that set the Questionable Status register group bits to enable specific conditions. Refer also to Figure C-4.

NOTE

PTR and NTR Filter programming is shown for consistency. In many cases, the default filter values make

 

programming them unnecessary.

 

 

Operation Status Group

Register Functions. The Operation Status registers record signals that are part of the power supply’s normal operation. As shown in Figure C-4, the group consists of a set of registers similar to the Questionable Status group. The output of the Operation Status group is logically-ORed into the OPER(ation) summary bit (7) of the Status Byte register.

Register Programming. Programming for this group is derived from the STAT:OPER commands (Table C-4).
