APPENDIX A - IEEE 488.2 COMMAND/QUERY DEFINITIONS

A.1

INTRODUCTION

This appendix defines the IEEE 488.2 commands and queries used with the BHK-MG Power Sup-
ply These commands and queries are preceded by an asterisk (*) and are defined and explained in
Figures A-1 through A-14, arranged in alphabetical order. Table A-1 provides a quick reference of
all IEEE 488.2 commands and queries supported in the BHK-MG Power Supply.

A.2

*CLS — CLEAR STATUS COMMAND

*CLS

Syntax:

*CLS

Description: Clears status data. Clears the following registers without affecting the corresponding Enable Regis-

ters: Standard Event Status Register (ESR), Operation Status Event Register, Questionable Status
Event Register, and Status Byte Register (STB). Also clears the Error Queue. Related commands:
*OPC, *OPC?. (See example, Figure A-1.)

A.3

*ESE — STANDARD EVENT STATUS ENABLE COMMAND

*ESE

Syntax:

*ESE where = positive whole number: 0 to 255 per Table A-2.
Default Value: 0

Description: This command programs the standard Event Status Enable register bits. The contents function

as a mask to determine which events of the Event Status Register (ESR) are allowed to set the ESB
(Event Summary Bit) of the Status Byte Register. Enables the Standard events to be summarized in
the Status Byte register (1 = set = enable function, 0 = reset = disable function). All of the enabled
events of the standard Event Status Enable register are logically ORed to cause ESB (bit 5) of the Sta-
tus Byte Register to be set (1 = set = enable, 0 = reset = disable)

(See example, Figure A-1.)

A.4

*ESE? — STANDARD EVENT STATUS ENABLE QUERY

*ESE?

Syntax:

*ESE?

Return value: Integer> value per Table A-2.

Description: Returns the mask stored in the Standard Event Status Enable Register. Contents of Standard

Event Status Enable register (*ESE) determine which bits of Standard Event Status register (*ESR)
are enabled, allowing them to be summarized in the Status Byte register (*STB). All of the enabled
events of the Standard Event Status Enable Register are logically ORed to cause ESB (bit 5) of the
Status Byte Register to be set (1 = set = enable function, 0 = reset = disable function). (See example,
Figure A-1.)
