U
OPTION 10
OPTION 33
u
Option 10
provides
a GPIB (
General
Purpose
Interface
Bus ) communications interface and , with the 2230 , addi
tional memory . The interface implemented conforms to the
specifications
contained
in IEEE
Standard Digital
Interface
for
Programmable
Instrumentation ( ANSI /
IEEE Std
488
1978 ) . It also
complies with a
Tektronix
Standard
relating
to GPIB
Codes ,
Formats
,
Conventions and
Features
.
Option 33 , the
Travel
Line
option
,
provides
impact
pro
tection
needed
for
rough
industrial
and
service
environments . When the instrument is ordered with Option
33 , it comes equipped with the Accessory Pouch , the
Front
Panel
cover , shock - absorbing rubber guards
mounted on
the
front and
rear
of the

ال
COMMUNICATIONS
OPTION
OPERATION
나
The
communications options
allow remote
waveform acquistion and the
transfer of
waveform data both to
and from the
oscilloscope
.
Waveform data may also
be
directly output to
compatible
digital
printers
or
plotters
for
producing
hardcopies
of
the
displayed
signals
.
1.
Query
the
state of the
oscilloscope
.
Remote
control
and waveform
transfer is
accomplished
by messages sent to the oscilloscope via one of the com
munication
option
interfaces
.
The
Option 10
interface
con
forms
to
GPIB
IEEE
- 488
bus
standard and the
Option 12
interface
conforms
to
the
standard for RS - 232 -
C serial
communication . Both
options
also
conform
to
Tektronix
standards on Codes , Formats , Conventions , and Features .
In general , messages to the oscilloscope sent via the
communication
options
have
one
of
the
following
purposes
:
u
u
2. Query the result of a measurement made .
3. Set or
change
the
instrument's
operating mode .
4. Request waveform data transfer .
