Capture
Data, Status,
And Handshake
Lines
The HP 10342B bus preprocessor
captures bus activity and
provides
inverse assembly for RS-232C/V
.24,
RS-449 *, and HP-IB**
buses . This bus
analysis tool combines
the power of a
logic analyzer with
the convenience of a
preprocessor,
yielding a truly easy-to-
use
instrument .
Simply select the appropriate
operating modes from the front of
the
HP 10342B, press run on your
logic
analyzer, and you will obtain a
listing of
your bus activity . The
inverse assembler
supplied with the HP 10342B
configures
* Support both
RS-422A (balanced) and
RS-423A (unbalanced) electrical
implementations .
** Hewlett-Packard's implementation of
IEEE-488 (1978) .
The
HP 10342B bus preprocessor connects to
the HP 10269B general-purpose probe
non-intrusive monitoring of HP-IB, RS-232CIV
.24, and RS-449 .
interface for direct and
and assigns labels to
the lines used in
the logic
analyzer .
The HP 10342B,
which is compatible
with all HP
1630A/D/G and
HP 1631A/D
logic analyzers, uses the
timing analyzer to
display the condition
of the handshake
lines when a character
is received
. Easy access to an
oscilloscope
for high-resolution timing
measurements can be made by
connecting any of the input
signal lines
to one of the three
probe sockets located
on the front
panel of the HP 10342B .
The HP
1631A/D's analog inputs can
digitize two
signals at 200
megasamples/second for 5-ns timing
resolution measurements . Time-consuming
transactions can be easily
identified
with the time-histogram mode
of the
HP 1630A/D/G and HP 1631A/D
logic analyzers . Time-tagging is
provided with the
HP 1630G to
measure the actual time
between states .
The HP 10342B Bus
Preprocessor
Provides :
Asynchronous protocol
- Data rates from
50
to
19 .2k bits per
second
- Even, odd, or no parity
- Six-bit transcode, seven-bit
or
eight-bit ASCII,
eight-bit EBCDIC
- 1, 1 .5, or 2 stop
bits
Synchronous
protocol
- Data rates to
72k bits per second
- Bit protocol
(SDLC, HDLC,
BSC, etc .)
- Character protocol
(six, seven, and
eight bit)
"
HP-IB
- Eight-bit
parallel ASCII
- Supports
all eight status bits
Inverse Assembly
The HP 10342B is supplied
with a
3-1/2 inch disc inverse
assembler . The
inverse assembler
converts the data and
status into
standard text for easy
interpretation .
In the
HP-IB mode, all data,
handshake,
and status lines are
monitored and
states displayed . For
RS-232C/V
.24 and RS-449, data and
five
handshake lines are monitored
and
displayed . Four of the handshake
lines
are synchronous with the
serial
controller . The fifth, the carrier detect,
is
asynchronous and is sampled each
time a character is sent to the
analyzer .
Labels and logic
analyzer
configurations are also
provided with the
inverse
assembler . This simplifies
operation so
you spend your time
making measurements rather than
manually configuring the
analyzer .
