Overview of Remote Control
Status Byte
When you read the contents of the operation status event register using the
:STAT:OPER:EVEN? query, the operation status event register is cleared, and
bit 7 of the status byte is reset to “0.”
Enabling the Operation Status Event Register
An operation status register summary (bit 7 of the status byte) will be set when
any enable bit in the operation status event register is set to “1.” To
enable/disable any bits of this register, the operation status event enable
register is used. This particular register is the same length as the operation
status event register. When a bit is set in the enable register, it enables the
corresponding bit in the event register to request a service. To set any bit in the
enable register, the :STAT:OPER:ENAB command is used. The syntax of the
:STAT:OPER:ENAB command is:
:STAT:OPER:ENAB <n>
where, <n>: decimal number (-32768 to 32767)
For example,
If <n> is equal to 8 (0000000000001000 in binary), bit 3 is enabled as follows.
In this case, when bit 3 of the operation status event register is set to “1,” the
operation status register summary (bit 7 of the status byte) is set to “1.”
The default setting is :STAT:OPER:ENAB 0 (all bits of the operation status event
register are disabled).
4 16 Measurement Complete Bit This bit is set to “1” when a single point measurement is
completed. This bit indicates a corrected measured value.
5 to 15 unused always 0 (zero)

Bit 1, bit 2, and bits 5 to 15 are always 0 (zero). Thus, it is meaningless to
mask them.
