B.117 STATus:QUEStionable:ENABle COMMAND
Syntax:
Short Form: STAT:QUES:ENAB <int_value>
Description: Programs Questionable Condition Enable Register (see Table B-4).The Questionable Condition
Enable Register determines which conditions are allowed to set the Questionable Condition Register;
it is a mask for enabling specific bits in the Questionable Event register that can cause the question-
able summary bit (bit 3) of the Status Byte register to be set. The questionable summary bit is the log-
ical OR of all the enabled bits in the Questionable Event register
(active, true); bit reset to 0 = function disabled (inactive, false)
NOTES: 1. The power supply is assumed to be operating in constant voltage (CV) mode.
2 Examples below are intended only to illustrate command functions. Refer to PAR. 3.5.2 for
programming techniques to optimize performance.

Sets output on.
Operation Condition and Questionable Condition registers are
reset.
Resets Enable Amplifier
Allows latching of CE and VE bits
Mask enabled for CC and CV bits.
Returns 1280 (256 + 1024) (CC and CV bits set).
Continuous triggers enabled.
Power supply returns 256 to indicate that power
supply is in constant voltage mode.
Commands power supply to current mode.
Returns 1024, indicating that since the last reading
of the Operation Event Register the power supply has entered
Constant Current mode.
Returns 0 indicating no changes since previous reading of the
Operation Event register.
Returns 0 (no questionable conditions occurred since previous
reading
--- OVERCURRENT CONDITION OCCURS
Power supply returns 0,"No error" message.
The BOP is in Voltage mode and delivering 5 Volts
Bop returns a 0 - all functions are normal
BOP is in Current mode
BOP returns 8;4097 - Current error.
BOP returns 0;4096 - no new errors, Current Error
BOP returns 0;0 - no new errors
BOP returns 1.0E-4;5.00003E0 - Voltage is 5 volts
BOP returns 4097 - error still in effect
Short is applied to the BOP
BOP returns 0;1 - Current mode is selected
BOP returns.1E-4;1.00003E0 - Current is 1 amperes
BOP switches mode, returns 3 - settling
BOP returns 8;8194
BOP returns 2, voltage mode operation OK.
