Model 2308 Portable Device Battery/Charger Simulator User’s Manual
Section 7: Status Structure
The commands to read the event registers are listed in
Table 7-5
. For details on reading registers,
see
Reading registers
.
Event enable registers
As
Figure 7-1
shows, each status register set has an enable register. Each event register bit is
logically ANDed (&) to a corresponding enable bit of an enable register. Therefore, when an event
bit is set and the corresponding enable bit is set (as programmed by the user), the output
(summary) of the register will set to 1, which in turn sets the summary bit of the status byte
register.
The commands to program and read the event enable registers are listed in
Table 7-6
. For
details on programming and reading registers, see
Programming enable registers
and
Reading
registers
.
Table 7-5
Common and SCPI commands - event registers
Command
Description
Default
*ESR?
Read standard event status register.
(Note)
STATus
:OPERation:[:EVENt]?
:MEASurement:[:EVENt]?
:QUEStionable:[:EVENt]?
STATus subsystem:
Read operation event register.
Read measurement event register.
Read questionable event register.
Note: Power-up and *CLS resets all bits of all event registers to 0. STATus:PRESet has no
effect.
NOTE
The bits of any enable register can be reset to 0 by sending the 0 parameter
value with the appropriate enable command (i.e. STATus:OPERation:ENABle 0).
