A.13 *STB? — STATUS BYTE REGISTER QUERY
*STB?
Syntax: *STB? Response: value from 0 to 255 per Table A-3.
Description: Reads Status Byte Register without clearing it. This Query reads the Status Byte Register (bit 6 =
MSS) without clearing it (1 = set = function enabled, 0 = reset = function disabled). The register is
cleared only when subsequent action clears all set bits. MSS is set when the power supply has one
ore more reasons for requesting service. (A serial poll also reads the Status Byte Register, except that
bit 6 = RQS, not MSS; ands RQS will be reset.) Related Commands: *SRE, *SRE?. (See example,
Figure A-1.)
A.14 *TRG — TRIGGER COMMAND
*TRG
Syntax: *TRG
Description: Triggers the power supply to be commanded to preprogrammed values of output current and
voltage. When the trigger is armed (checked by examining WTG bit in Status Operational Condition
register) *TRG generates a trigger signal. The trigger will change the output of the power supply to the
output voltage and current levels specified by VOLT:TRIG and CURR:TRIG commands and clear the
WTG bit in the Status Operation
Condition register. If INIT:CONT has been issued, the trigger
subsystem is immediately rearmed for subsequent triggers, and the WTG bit is again set to
1. *TRG or GET are both addressed commands (only devices selected as listeners will exe-
cute the command). Related Commands: ABOR, INIT, TRIG, CURR:TRIG, VOLT:TRIG. (See
example, Figure A-1. )
