Solartron 1260 - For IEEE 488 Protocol

2.6 PARALLEL
POLL
The
instrument can
be
configured
to give
a
parallel
poll trueifalse response on a
selected
GPIB data line,
to
indicate
whether or not the
instrument is requesting
service. However,
the instrument must
first be
configured for
serial
poll (see
Section
2.5.1 above).
To set up
a
parallel
poll configuration send the remote
command PPn, where n is an
integer from 1
to 8 defining which GPIB data line is to
carry the response.
Setting PARALLEL
POLL to zero or sending PPO
unconfigures parallel poll.
To select the
sense of the parallel
poll
line
send the remote command PSn, where
n
=
1
signifies true and
n
=
0 signifies
false.
The parallel
poll response is also
cleared
by
any change
to
the SERIAL POLL value,
by any BREAK
action-key selection, and by
power-off.
Unlike serial poll,
parallel
poll
need
not
be
reconfigured after each service request. It
is, however, cleared
by the
command *SREn.
2.7 SUMMARY OF COMMANDS FOR IEEE 488 PROTOCOL
The
following
comands
are
supported by the instrument for IEEE
488
protocol:
Cmd Action
*RST Reset command, equivalent
to the
break command (BK).
*CLS Clears the
status byte register and the
event
status register. Any *OPC
command
is cancelled.
*STB? Queries
the status byte register, leaving it unchanged.
*SREn Sets the service
request
enable register
to
the bit pattern corresponding
to
n.
*SRE? Queries the
service request enable
register, leaving
it unchanged.
*ESR? Queries
the
event
status register,
clearing it
in the process.
*ESEn Sets the event
status enable register to the bit pattern corresponding
to
n.
*ESE? Queries
the event status enable register, leaving it unchanged.
*OPC Enables
the instrument
to set
the operation complete
bit
in
the event status
register
when the idle state is next entered.
*IDN
Intrument
outputs
the identifier string
"SCHLUMBERGER
TECHNOLOGIES, 1260 IMPEDANCE ANALYZER,
0,
0”
*TST?
Starts
a
self
test,
on completion of which the instrument
outputs the result:
"0”
for
fail
or
"1”
for
pass.
The front panel is
left in self test mode, scrolling
the
rows.
The
next command clears this,
or the operator can clear it by
keying
ENTER twice.
*RCLn
Recalls a
stored
setup. Equivalent action to the
RS/ command.
*SAVn Stores
the present setup. Equivalent action
to
the
SS/ command.
