Command Description
ASTS? Returns 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. Bits in the accumulated status register
represent the same bits and conditions as the bits in 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
49. The ASTS? query clears the accumulated 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> Sets the AUXA output signal level at rear panel connector J7-7. Active low.
Initial value: AUXA 0
AUXA? Returns 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 J7-8. Active
low.
Initial value: AUXB 0
AUXB? Returns 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? Returns the power supply’s calibration mode status.
Response: CMODE 0 (disabled)
CMODE 1 (enabled)
