STATus:QUEStionable:ENABle <numeric_value>
This command sets the Questionable Status Enable Register. This register de-
termines which event bits of the Questionable Status Event Register affect the
Questionable Status Bit (QSB, bit 3) of the Status Byte Register. If any bit of
the Questionable Status Event Register is set (1) while its corresponding mask
bit of the Questionable Status Enable Register is set, the QSB bit in the Status
Byte Register will be set. The value of the <numeric_value> parameter is a
number from 0 to 65535 that is the sum of the binary-weighted values of each
mask bit. The Questionable Status Event Register is described in Section
6.5.10.20.
STATus:QUEStionable:ENABle?
This query command returns the Questionable Status Enable Register (see
6.5.10.18 above).
STATus:QUEStionable[:EVENt]?
This query command reads the Questionable Status Event Register. Reading
this register clears it. The value returned indicates the condition of each of the
eight bits of the register by adding the binary-weighted values of each bit. The
meaning of each bit, when set (1), is as follows where 0 is the least significant
and 7 is the most significant:
0-3 No function, always 0.
4
Temperature. A previous temperature measurement was out-of-range or
otherwise questionable.
5-15No function, always 0.
STATus:QUEue[:NEXT]?
This query command functions identically to the SYST:ERR? command (see
below).
SYSTem:ERRor?
This query command returns a system error message if any are present in the
system error queue. Each error condition produces only one error message at a
time. The error queue may contain up to two messages. Messages are reported
in the order they occur. Reading a message from the queue removes the mes-
sage so the next message can be read. If more than two errors occur before be-
ing read the second error in the queue will be "Queue overflow" and all but the
first error will be discarded. Any error will also cause the Error Bit (ERR, bit 2)
of the Status Byte Register (Section 6.5.10.9) to be set. This command returns
error messages in the following format:
<error_number>,"<error_description>"
