Explanation of Examples

Example 1:

Allow an overtemperature event to set the QUES summary bit.

STAT:QUES:ENAB 16;PTR 16

Example 2:

Allow both an unregulated event and the removal of that event to set the QUES summary bit

STAT:QUES:ENAB 1024;PTR 1024;NTR 1024

Example 3:

Prevent any remote inhibit event from setting the QUES summary bit.

STAT:QUES:ENAB 0

(or any value that does

not

set bit 9)

Example 4:

Allow only the removal of an existing remote inhibit event to set the QUES summary bit

STAT:QUES:ENAB 512;NTR 512

Notes:

Boldface (1) indicates programmed state; italic (1) indicates signal state. "x’’ = ’’don’t care’ condition.

Status Programming Example.

Control over Conditional Status events is the same as for Questionable Status events. See

Table C-1 for register configurations.

STAT:OPER:ENAN 32;NTR 32
Allow the OPER summary bit to be set whenever the power supply leaves CV mode

Standard Event Status Group

Register Functions.

The Standard Event Status group consists of two registers (Event and Enable) that are progammed by

common commands, not by STAT subsystem commands.

The Standard Event register latches events relating to interface communication status (see Table C-1). It is a readonly
register that is cleared when read.

The Standard Event Enable register is a read/write register that functions similarly to the enable registers of the Operation
and Questionable status groups.
