The Questionable Status Event Register is cleared to 0. It is
read using the STATUS:QUESTIONABLE:EVENT? Query.
*ESE Command
The *ESE command sets the value of the Standard Event Status
Enable Register . The value of this register is logically ANDed with
the contents of the Standard Event Status Register (see the *ESR?
query description). If any bits of this AND operation are set, then
bit 5 of the Status Byte is set. Bit 5 is known as the Event
Summary Bit, or ESB, and is shown in Figure 2-3.
ESB of Status Byte =
(bit 0 of ESE AND bit 0 of ESR)
OR
(bit 1 of ESE AND bit 1 of ESR)
OR
(bit 2 of ESE AND bit 2 of ESR)
OR
(bit 3 of ESE AND bit 3 of ESR)
OR
(bit 4 of ESE AND bit 4 of ESR)
OR
(bit 5 of ESE AND bit 5 of ESR)
OR
(bit 7 of ESE AND bit 7 of ESR)
where:
ESE is the value as set by the *ESE command
ESR is the value which may be read with *ESR? query
The *ESE command has the format:
*ESE <ESE value>
where the “<ESE value>” is an integer numeric value in the range
from 0 through 255.
