z Event Status Enable Register (ESER)

z OPERation Enable Register

z QUEStionable Enable Register

z Service Request Enable Register (SRER)

When one of the bits of the enable registers is high and the corresponding

bit in the status register is high, the enable registers will perform a

logical OR function, the output that controls the set bit of the Status Byte

Various commands set the bits in the enable registers. The following

sections describe the enable registers and the commands that set them.

Event Status Enable Register (ESER)

: The ESER controls which types of

events are summarized by the Event Status Bit (ESB) in the SBR. The

bits of the ESER correspond to the bits of the SESR.

Use the *ESE command to set the bits in ESER. Use the *ESE? query to

read it.

OPERation Enable Register

: Even though the OPERation Enable

any conditions.

QUEStionable Enable Register

: The QUEStionable Enable Register

controls which types of events are summarized by the QUES status bit in

the SBR. Use the STATus:QUEStionable:ENABle command to set

the bits in the QUEStionable Enable register. Use the

STATus:QUEStionable:ENABle? query to read it.

Service Request Enable Register (SRER)

: The SRER controls which bits

in the SBR generate a service request.

Use the *SRE command to set the SRER. Use the *SRE? query to read

it.

Queues

The output queue is included to power supplies.

Output Queue

: The DMM store query responses in the output queue by

succeeding the IEEE 488.2 protocol. If the DMM receives a new

command or query message after a message terminator, the DMM will

clear and reset this queue each time. The computer must read a query

response before it sends the next command (or query) or it loses response

to earlier queries.

Error/Event Queues

When an error or event occurs, the output queue stores the message. The

output queue stores and reports the messages on a FIFO (first in first out)

state. The SYSTem:ERRor? query reads the next item from the output

queue. If output queue overflows, the error message is –350, “Queue

overflow”; the queue can’t store or report succeeding messages till it

is read or cleared.

Error Message

Table 8 lists the SCPI error messages for the DMM.

Table 8 The error messages for the DMM:
