A query error indicates that the output queue control has detected a problem. This could occur if
either an attempt was made to read data from the instrument if none was available, or when data
were lost. Data could be lost when a query causes data to be formatted for the controller to be read,
and the controller sends more commands without reading the data.

System Events
System events have positive valued codes. They are not defined by SCPI, but are specific to the
instrument. Sending the :STATus:PRESet command will disable these events from being reported.

Warnings
The execution of some commands might cause an undesirable instrument state. The commands are
executed, but a warning is issued. Sending the :STATus:PRESet command disables reporting of
warnings. The existence of these conditions causes a bit in the Status Questionable Condition register
to be set (refer to section Questionable Condition).

"Trigger rate short" means that the period of the waveform is larger than the value of the internal
trigger rate. Thus not every trigger will generate a cycle (or burst) of the waveform.

Query INTERRUPTED.
Data were sent before the entire response of a previous query was read.
Query UNTERMINATED.
An attempt was made to read a response before the complete program
message meant to generate that response was sent.
Query DEADLOCKED.
The input buffer and output queue are full, and the controller is
attempting to send more data. In this case the output queue and input
buffers will be cleared. Parsing will resume after the END message is
detected.
Query UNTERMINATED after indefinite response.
A query was received in the same program message after a query
requiring an indefinite response was formatted. Essentially this means
that the *IDN? common query and the :ARB:DATA? query should not be
followed by more query messages in the same program message.
Power on
Operation complete
The *OPC command has been executed.
Trigger rate short on channel 1
Trigger rate short on channel 2
Output overload on channel 1
