About the interface cards
*SRE?
Reads the Service Request Enable Register
*STB?
Reads the Status Byte Register, which is cle-
ared after reading
Service Request (SRQ) generation
The GPIB controller automatically handles the actions that
are triggered by the bit rsv in the status register STB.
After generating a service request and subsequent query
with *STB? from the host, the register is cleared.
The scheme is illustrated in the diagramm below.
A SRQ is generated as soon as the bit rsv in the Status Byte
register (STB) is set and the corresponding bits for events
that can cause a SRQ are activated in the Service Request
Enable Register (SRE).
Which events can cause a service request is selected with
the Service Request Enable Register by the command *SRE
<CHAR>.
The status register STB consists of these bits:

Bit :
err, Error queue full; this queue is cleared by reading
it and the bit is also reset. The list can hold up to 4
of the last errors
Bit 3:
ques, Questionable status register is active (on or
more events have occured)
Bit 4:
Not used
Bit 5:
esr, the standard Event Status Register (ESR), mas-
ked by the Event Status Enable Register (ESE), is
signalising that one or more events have occured
Bit 6:
rsv, always active
Bit 7:
oper, signalises, that one or more events have
occured and are stored in the Operation Status
Register
The event bits of the various registers report to the STB, if
events have occured that are enabled to be reported, by the
corresponding bits in the enable registers (*ESE, *SRE resp.
STAT:QUES:ENAB, STAT:OPER:ENAB).
