Getting
Started
This
chapter
describes
the
use
of
the
MB100
Multi
- Channel
BER
Tester
Remote
Interfaces .
Since the
remote
interfaces
enable automatic
testing ,
the user
does not
have
to
complete
any of the
manual
procedures
necessary for
front
panel
operation
.
However
, the
user
can write
programs
to
conduct
the
test
sessions
.
Using
the
GPIB
Interface
The
MB100
supports
remote
control
through
the
GPIB
interface
bus
connector
on
the
rear panel .
The
unit
can
be
operated
from the
front
panel
and over
the
remote
interface simultaneously
. Any unit
changes made
remotely are
displayed
on
the
front
panel . All
of the
front
panel
functions can
be
controlled
over
the
GPIB
interface
, except
`
POWER . '
Remote
commands
sent to the
MB100
differ from
front
panel control . The
current
operating
mode is
entered
directly
rather
than
through
submenus .
GPIB Interface Device Settings
For
proper
GPIB
Interface
communication
and
handshaking
, the
GPIB
controller
(
system
that
controls
the
operation )
and
the
device (
MB100
)
must
have
their
addresses
and
terminating
characters
set up
before
use . To
change
these
GPIB
parameters
,
refer to
the section
in
this
manual on
"
Utility ”
.
Each
instrument
on the
GPIB
interface
bus
needs a
unique
INSTRUMENT
address
.
The
INSTRUMENT
address
range for the
MB100
is
- 30
decimals
.
The
GPIB
Message
Terminator is et
to either
EOI
or
EOL
/
LF . For
EOI
, the
EOI
line
will be
asserted when
the last byte of
a message
is transmitted
. For EOI / LF
,
the
last byte
of the
message
will be the
line feed
character
,
and the
EOI
line will
be
asserted
with its
transmission .

uses
the
standard

24 pin
GPIB

on the
rear
panel
.
All
signals
and
pins
conform
to
the

GPIB
Remote
Commands
There
are
two
types
of
remote
commands
for
the
MB100
:
Set
commands
(
commands )
Queries
commands
(
queries
The
set
commands
force
the
MB100
to
take a
specific
action .
The
query
commands
direct
the
MB100 to
return
status
information
.
The
controller
sends
commands to
the
MB100
as
strings
terminated at
EOI
or
EOI /
LF
characters
.
These
command
lines
can
contain
either a
single
command
or
multiple
commands
.
The
command
line
may
contain
both
queries
and
commands
.
Each
individual
command
within
the
command
line must
be
separated by
semi -
colons
(
; ) ,
parameters
must be
separated
by
comma ( , )
.
Hexadecimal
parameters must
be
preceded
by
a '
#H
' .
Each
query
command
sent
to
the
MB100
will return
one

Status
Reporting
There
is a
status
reporting
function
provided
for the
GPIB
interface
,
which
is
based on
the
SRQ (
Service
Request ) and
is
defined in
the
ANSI /
IEEE
standard
488.2-1987
. The
implementation
used by
MB100 for status
reporting includes
one
additional
register
from what is
specified
within the
IEEE -
488.2
standard
.
Status
Byte
Bits 1 to 3
Bit

There is
a status byte
which is
used to
define the
SRQ status .
The
individual bits
within the
status
byte represent

which might
cause
the

Different

contains
the

For

,
either

Service Request ( SRQ )
The

enables
the
creation of
a

Whenever
a
condition
requiring
service
from
the

occurs
and is
enabled ,
the
SRQ
line is
set . It
is
reset
after
the

Standard Event Status Enable Register
Different conditions within the Standard Event Status Register can be
individually
enabled or
disabled . The
Standard Event Status
Enable
Register
contains
enabling
bits .
Each time one
of the
event
conditions or
one of the
enabling bits
change
, the
status of the ESB
bit is re
- evaluated
. If any
status bit is
set
and its
corresponding
enable bit
is set
, the
ESB bit is
set
also .
Each
time the
MB100
is powered
on , this byte
is reset so
that no bits
are
enabled .
The bit
definition
for the
Standard
Event
Status Enable
Register
is the
same as it
is for the
Standard
Event Status
Register
.
Test Status Event Register
The
TSB bit is the
summary of the
Test
Status
Event
Register . This
byte
has
an
enabling
byte which
works
in a
similar
manner
to the
above
Status

The
individual bits
within
the
Test

The
different
conditions
within the Test
Status

Register can
be
individually
enabled and

. The
Test

Enable
Register
contains
enabling
bits .
Each
time one of
the
event
conditions or
one of
the
enabling
bits change ,
the
status of the
TSB bit is
re - evaluated
. If
any status bit
is
set
and its
corresponding
enable

is set
,
the TSB bit
will
set .
Each
time

IEEE - 488.2 Programming Manual Requirements
Certain
programming
requirements
are
specified
for GPIB
interfaces
by
the
American
National
Standard
Institute
( ANSI )
document
,
ANSI / IEEE
Std .
488.2
1987 ,
which
are detailed
in
this
section .
Power - on
settings
The
MB100
will restore
the
device
settings
to
their same
values
from when it
was
last powered
off
. No
remote
commands
affect
this .
The
only exception
to
this
is
when the non
- volatile
RAM
becomes
corrupted (
which should
never
happen
during
normal
operation
) .
RAM
corruption ,
if it
occurs ,
will be
displayed
on
the
unit's
LCD
display
. When
this happens
, the
MB100
will revert
to its
factory
- default
settings
.
Message
Exchange
The
message
exchange
options
are
as
follows :
The
input buffer
is
command
line oriented .
There is
a
new input
buffer for
each
command
line or
program
message
.
The
maximum
input
buffer
length
is
80
characters .
The only remote commands that return more than one response message unit
are
: * Irn ?,
meas_all ?,
meas_agg ?.
All
queries
immediately
generate
their own
response
messages
when parsed .
No
queries
wait
until
the
responses
are
read for
them
to
be
generated .
No commands are coupled .

Functional Elements
The IEEE 488.2 standard requires a list of the functional elements which are
used
by the
MB100
receiver . These
are the
functional
elements used in
constructing
the remote

that
control the
receiver . For more
information , see
the IEEE 488.2
standard
,
sections 4.3 , 7.1.1
, and 7.3.3 . From

interface ,
except
