APPENDIX B - SCPI COMMAND/QUERY DEFINITIONS

B.1

INTRODUCTION

This appendix defines the SCPI subsystem commands and queries used with the BIT 4882 and BIT
4882-F Interface Cards. Subsystem commands are de

+fined in PAR. B.2 through B.25, arranged in groups as they appear in the tree diagram, Figure
4-1. Table B-1 provides a quick reference of all SCPI subsystem commands and queries used in
the Interface Card.

B.2

INITiate[:IMMediate]

COMMAND

INIT[:IMM]

Syntax:

Short Form: INIT:[IMM] Long Form: INITiate[:IMMediate]

Description:

Enables a single trigger. This command enables a single trigger. A *TRG command completes the
sequence. Upon receipt of the *TRG command, the power supply will return to the commanded values
of voltage and current established by the VOLT:TRIG and CURR:TRIG commands. After a *TRG com-
mand has been received, subsequent *TRG commands have no effect unless preceded by INIT or
INIT:CONT ON. Related Commands: *TRG, TRIG. (See example, Figure B-1.)

B.3

INITiate:CONTinuous COMMAND

INIT:CONT

Syntax:

Short Form: INIT:CONT {ON | OFF} or {1 | 0} ( 1 = on, 0 = off)
Long Form: INITiate:CONTinuous {ON | OFF} or {1 | 0} ( 1 = on, 0 = off)

Description:

INIT:CONT ON enables continuous triggers.; INIT:CONT OFF disables continuous triggers. If
INIT:CONT is OFF, then INIT[:IMM] arms the trigger system for a single trigger. If INIT:CONT is ON,
then the trigger system is continuously armed and INIT[:IMM] is redundant. Executing *RST command
sets INIT:CONT to OFF. (See example, Figure B-1.)

B.4

INITiate:CONTinuous

QUERY

INIT:CONT?

Syntax:

Short Form: INIT:CONT?

Long Form: INITiate:CONTinuous?

Return Value: 1 or 0

Description:

Determines whether continuous triggers are enabled or disabled. Power supply returns value of
INIT:CONT flag: “1” = continuous triggers are enabled (INIT:CONT ON); “0” = continuous triggers dis-
abled (INIT:CONT OFF). (See example, Figure B-1.)
