DDE
1 - Device Dependent
(specific) Error occurred.
(specific) Error occurred.
The Device specific Error (DDE) is set true (1) whenever
a hardware failure has occurred at power-up or at
execution time, such as a channel overload condition,
or a trigger or timebase circuit defect. The origin of the
failure can be localized with the DDR? query.

QYE
1 - QuerY Error occurred. The QuerY Error bit (QYE) is set true (1) whenever (a)
an attempt is made to read data from the Output
Queue when no output is either present or pending, (b)
data in the Output Queue has been lost, (c) both
output and input buffers are full (deadlock state), (d)
an attempt is made by the controller to read before
having sent an <END>, (e) a command is received
before the response to the previous query was read
(output buffer flushed).

RQC
0 - Oscilloscope never
ReQuests bus Control.
ReQuests bus Control.
The ReQuest Control bit (RQC) is always false (0), as the
oscilloscope has no GPIB controlling capability.

OPC
0 - OPeration Complete
bit not used.
bit not used.
The OPeration Complete bit (OPC) is set true (1)
whenever *OPC has been received, since commands
and queries are strictly executed in sequential order.
The oscilloscope starts processing a command only
when the previous command has been entirely
executed

STATUS - *OPC
Description
The *OPC (OPeration Complete) command sets to true the OPC bit (bit 0) in the Standard Event
Status Register (ESR).
Status Register (ESR).
The *OPC? query always responds with the ASCII character 1 because the oscilloscope only
responds to the query when the previous commands are entirely executed. Since *OPC?
executes only when processing is complete, it is recommended for synchronization purposes.
