3.3 Command Reference
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
Section 3.4 Accumulated Status, Status, and Fault Registers. The 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 <state >
Parameters:
1/ON, 0/OFF
Controls the AUXA output signal level at rear panel connector J7
-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 <state >
Parameters:
1/ON, 0/OFF
Controls the AUXB output signal level at rear panel connector J7
-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 Table 2.5-1 Remote Mode
Power On Default Settings. These default settings will not come into effect until the
power supply is switched to remote mode operation.
CLR will not reset AUXA, AUXB, or
CMODE.
CMODE <state>
Parameters:
1/ON, 0/OFF
CMODE ON places the power supply into calibration mode for processing calibration
commands.
Initial value:
CMODE 0 (OFF)
