Model 2700 Multimeter/Switch System User’s Manual Status Structure 11-19
Event enable registers
As Figure 11-1 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 11-5 . For
details on programming and reading registers, see “Programming enable registers,”
page 11-5 , and “Reading registers,” page 11-6 .
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).

Event enable registers commands
Command Description
*ESE <NRf> Program Standard Event Enable Register (0 to 255).
*ESE? Read Standard Event Enable Register.
STATus:OPERation:ENABle <NRF> Program Operation Event Enable Register (0 to 32767).
STATus:OPERation:ENABle? Read enable register.
STATus:MEASurement:ENABle <NRf> Program Measurement Event Enable Register (0 to 32767).
STATus:MEASurement:ENABle? Read enable register.
STATus:QUEStionable:ENABle <NRf> Program Questionable Event Enable Register (0 to 32767).
STATus:QUEStionable:ENABle? Read enable register.
Note: Power-up and STATus:PRESet resets all bits of all enable registers to 0. *CLS has no effect.
