PWR-01 Interface Manual
Event status register
The event status register bits are set when certain events occur during PWR-01
operation. All bits of the event status register are set by the error event queue.
The register is defined by the IEEE488.2 standard and is controlled by the
IEEE488.2 common commands *ESE, *ESE?, and *ESR?.
See SYST:ERR? for the descriptions of the errors.

Query Error(QYE)
Set when an attempt is made to read data
from the output queue when there is no
output or the error queue is in wait status.
Indicates that there is no data in the error
queue.

Device Dependent
Error(DDE)
Set when there is a device-specific error. -300 to -399
100 to 999

16
Execution Error(EXE) Set when the PWR-01 evaluates that
the program data following the header is
outside the formal input range or does not
match the performance of the PWR-01.
This indicates that a valid SCPI command
may not be executed correctly depending
on the conditions of the PWR-01.

Command Error(C-
ME)
ISet when an IEEE 488.2 syntax error is
detected, when an unidentifiable header is
received, or when a group execution trig-
ger enters the internal IEEE 488.2 SCPI
command input buffer.
