The Standard Event group is programmed with Common commands
as described later in this section. Common commands also control
additional status functions such as the Service Request Enable and
the Status Byte registers.
STATus:PRESet
This command sets all defined bits in the Operation and Questionable
PTR registers. The command clears all defined bits in the Operation
and Questionable NTR and Enable registers.
STATus:OPERation[:EVENt]?
This query returns the value of the Operation Event register. The
Event register is a read-only register, which stores (latches) all events
that are passed by the Operation NTR and/or PTR filter. Reading the
Operation Event register clears it. The bit configuration of the
Operation status registers is as follows:
Bit Position
15-11 10
9

7-6
5
4-0

CC = The output is in constant current
CV = The output is in constant voltage
WTG = The unit is waiting for a transient trigger
STATus:OPERation:CONDition?
This query returns the value of the Operation Condition register.
That is a read-only register, which holds the live (unlatched)
operational status of the power supply.
STATus:OPERation:ENABle <value>
STATus:OPERation:ENABle?
This command and its query set and read the value of the
Operational Enable register. This register is a mask for enabling
specific bits from the Operation Event register to set the operation
summary bit (OPER) of the Status Byte register. This bit (bit 7) is the
logical OR of all the Operational Event register bits that are enabled
by the Status Operation Enable register. The Preset value = 0.
