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-3.)

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
disabled (INIT:CONT OFF). (See example, Figure B-3.)

B.5

INSTrument:CATalog? QUERY

INST:CAT?

Syntax:

Short Form: INST:CAT?

Long Form: :INSTrument:CATalog?

Return Value: comma separated string with the instrument numbers found on the bitbus.

Description: Allows the host computer to determine what instruments are on the bitbus. Unlike the *RST com-

mand, this command does not scan possible bitbus addresses to determine if the device is present.
The list contains all channel numbers found and allows the host computer to determine if the power
supplies are connected and powered-up (see Figure B-1).
