Auto Save... Long Recording Time
The auto save function makes it possible to continuously save up to 2Gbyte(*). It automatically saves the content of the capture memory on a high capacity compact flash (CF) card. And it continuously saves data into the measurement log of a user-specified file size, using ring recording as long as the card has space. In addition, it is useful for identifying rare communication failures of the unknown cause.
*Before using MC-2GCF
If you are using LE-3200-E with the version such as 1.09 or before, please update to 1.10 or later.
Firmware is available for downloading from the
support
page.
*Calculated for multiplexed transmission of
1,000 byte data frames per sec. Both transmission and
reception data consume 4 byte of memory with each
capture.
Logic Analyzer Display
Analyzes timing trouble in bits
Communication line timing is
analyzed and displayed as a logic analyzer display to a
time resolution of max. 50ns. This function helps to
identify the problems with hardware. Also, you can use
it as educational use, comparing documents for
communications protocol.

Online Monitoring
The online monitor feature
records communications data in the capture memory and provides
an easy-to-understand display for the type of protocol,
without affecting the communication line. LINE EYE protocol
analyzers record not only communications data but the time
(time stamp) of transmission and reception as well as idle
time. Therefore, failure time and timeout status can be
checked. In addition, it is available for the trigger function
which detects specific communication conditions and for the
recording function to select the specific address frames which
helps you to effectively use the memory.
Depending on the
test, you can select bit transfer sequence and polarity, as
well as modulation format from NRZ, NRZI, FMO, FM1 and 4PPM.
The feature allows to support effective analysis by omitting
SYN codes and using SDLC/HDLC address filter.

Time Stamp Measurement
Record the data and the time of transmission / reception for data frames. ASYNC cannot recognize the length of frame.
Thus, our analyzers decide the frame end when it find the specific character, or
when it pass the specific time of being non-communication.
Time stamp will be displayed in above 2 situations.
* Specifies OFF, day / hour / minute, hour
/ minute / second, or minute / second / 10msec.
Non-communication state which works as the frame end detection time of ASYNC and Burst communications can be set from 1 to 100ms.
* The example indicates that received time of last data was 20min. 56.37sec(M / S / 10mS setting)
* If there are some frame with same time stamp, it is because the analyzer measured the frames in 10ms.
Idle Time Measurement
The amount of idle time between communications frames can
be measured.
* Specifies OFF or a resolution of 100msec.,
10msec. or 1msec.
* The example indicates there was an idle time of 7 to 7.9ms(1mS setting)
Trigger Function
| The trigger feature allows you to specify
a communications event as the trigger condition and have
measurement operations executed automatically when that
condition is specified. Up to four pairs of conditions
and operations can be set, which is helpful towards
identifying frequent intermittent faults that occurs with communications systems.
And, the operation of a trigger condition can be
specified as the condition for another trigger, making
it possible to analyze complicated operations based on
sequential trigger.

Statistical Analysis Measurement

 |
Statistic can be compiled for
transmission and reception data sets, frames and the
number of established trigger events, and subsequently
displayed as a graph (Unit: 1 to 240min.). This helps to
understand communications traffic and error frequency
for a specific time period. |
Monitor Condition Auto Setting
Communications data received is analyzed. And the
following basic measurement conditions are automatically set
based on the findings: communication speed, the character
framing, data code, SYNC character, BCC/FCS, etc.
*Auto setting may be disabled
when there is little data on the communication line or
when data included a lot errors.
*Maximum speed for auto setting is
115.2kbps.

Delay Time Measurement
| Enables to measure min. / max. / average
time of until some signal state is changed to another
state and the number of its times. It is useful for
delay analysis of control line RTS-CTS and so on. |

Simulations
With the simulation feature,
LINE EYE protocol analyzers act as the counterpart to
the target device and perform transmission and reception
tests according to protocol. Even in the early stages of
development when matching devices are not available,
tests can be run at near to actual operatingstatus.
After performing the step-by-step check of the
communications protocol in the analyzer's ownoriginal
MANUAL mode, the developer can create a simple program
to branch conditions using the menu selection and test
more complicated communications protocols.
Example of connection for simulation
Communications speed can be freely set.
Therefore, margins can be evaluated by intentionally
shifting communications speed, and error response
processing can be checked using test data that mixes in
data with parity errors.

MANUAL Mode
| The manual mode allows you to
send data registered in the transmission table which
corresponds to the "0" to the "F" keys. Data can be sent
with the press of a key. While checking replies from a
unit under development with the
analyzer's monitoring feature, you can easily and simply
test the communications process. You can also send fixed
data by registering it under a key combination of the
SHIFT and "0" to the "D" keys, as well as turn RS and ER
signal lines on/off with the SHIFT and the "E"/"F" key
combinations. |
< Transmission table setup display
>
 |
FLOW Mode
| Flow control can be simulated on
the transmission and reception-lines using X-on/off flow
control or the control line handshake. In the
transmission mode, up to sixteen cycles of data from
transmission start until a generated
interrupt request can be displayed. In the reception
mode, you can set the number of received data cycles
until a transmission interrupt request is generated, as
well as the time until the transmission resume request
is generated. |
< Flow mode setup display

 |
ECHO Mode
In the echo mode, the analyzer internally return received
data in units of bits, bytes or frames (character string). It
is used to test display terminals and communications
terminals, and to set loop-back points for the BERT feature.
POLLING Mode
| The polling mode simulates the
slave and master units in multidrop (1:N connection)
polling protocols. In the slave mode,
the analyzer check the number of received frames that
are assigned their address and whether errors occur or
not, replying with user-set data. In the master mode,
they send polling messages to thirty two slave units,
and check and display replies from each slave. |
< Polling setup >
 |
BUFFER Mode
| In the buffer mode, you can
select transmission or reception, and send transmitted
and received data that has been captured in the
buffer using the unit's monitoring capabilities, as
simulation data without requiring further manipulation.
This mode is effective in conducting reproducibility
tests using the same data as that monitored under actual
communications conditions. |
< Buffer data reproduction setup

 |
PROGRAM Mode
| By creating a
purpose-specific command program, the communications
protocol can be flexibly simulated alongside condition
monitoring. The program is created using the menu
selection, so it is easy to master. |

BERT(Bit Error Rate Test)
BERT support enables you to
measure transmission quality of communications lines by
a loop-back or interactive connection. It is possible to
measure evaluation parameters (bit error count, block
error count) conforming to ITU-T G.821 Notification,
hence enabling bit error rate evaluations and fault
point identification. Elaborate test patterns and
functions such as bit error forced interrupt are
comparable to dedicated equipment.
< BERT display >
This function allows
to analyze in the ASYNC or SYNC mode by selecting
test mode (CONTINUE, R-BIT, RUN TIME and Repeat) and test
patterns.

Starting measurement
updates the measured results of line quality in
real
time. With REPEAT mode, you can know the bit error rate of every specific time on a communication circuit. |

PC Compatible File Management Specification
Test conditions and results such as measured data can be
saved on microdrives, compact flash cards and other memory
cards in the file management format compatible with your PC.
Of course, files can be interchangeably used between models
such as LE-7200-E, LE-3200-E, LE-2200-E, and LE-1200-E.
Therefore, measurement data can be saved on-site with
LE-3200-E, and analyzed or manipulated in greater detail using
LE-7200-E back in the office.
