Command Description
ASTS? Asks for the supply’s accumulated status register. The accumulated status
register stores any bit that was entered in the status register since the
accumulated status query command (ASTS?) was last used, regardless of
whether the condition still exists. The accumulated status register has the
same bits, weights, and conditions as the status register. A bit in the
accumulated status register will be set at 1 if the corresponding bit in the
status register has been 1 (TRUE) at any time since the register was last
read. See
“Accumulated Status, Status, and Fault Registers” on page 46.
The ASTS? query clears the status register.
Response: ASTS <status mask> where status mask is the decimal
equivalent of the total bit weights for the operating conditions as listed in the
status register.
AUXA <1/ON>,<0/OFF> Controls the AUXA output signal level at rear panel connector J21-7. Active
low.
Initial value: AUXA 0
AUXA? Asks for the present set value of the AUXA output signal.
Response: AUXA 0 (OFF)
AUXA 1 (ON)
AUXB <1/ON>,<0/OFF> Controls the AUXB output signal level at rear panel connector J21-8. Active
low.
Initial value: AUXB 0
AUXB? Asks for the present set value of the AUXB output signal.
Response: AUXB 0 (OFF)
AUXB 1 (ON)
CLR Initializes the power supply to its power ON condition. If issued while in local
mode, CLR will force power supply settings to register default values as in
but these default settings will not come into effect until the power supply is
switched to remote mode operation. The CLR commands will clear faults
from the fault register. CLR will not reset CMODE.
CMODE <1/ON>,<0/OFF> CMODE ON places the power supply into calibration mode for processing
calibration commands.
Initial value: CMODE OFF or CMODE 0
CMODE? Asks for the power supply’s calibration mode status.
Response: CMODE 0 (disabled)
CMODE 1 (enabled)
