Display of Two Divided Areas for Ease of Comparison [New Function]
[Example of two divided areas]
The display of two divided areas is convenient for the comparison of normal and abnormal communications log records.
It is possible to scroll the two divided areas on the upper half and lower half of the screen individually or simultaneously, which allows the comparison of the two communications records efficiently.
Freely Set with Four Effective Digits for Transmission and Reception
[Example of communications protocol settings]
Using high-precision DPLL technology for open baud rate support, transmission and reception speeds can be separately set with 4 effective digits to a baud rate range between 50 bps and 4 Mbps.
The required conditions of transmission or reception data, such as the bit configuration, bit transfer sequence, polarity, and modulation format can be freely selected to meet many test situations.
High-precision Time Stamp Recorded at 1-μs Intervals [New Function]
The time stamp shows the transmission or reception time of the head data of each communications frame.
In addition to the conventional real-time time stamp, the LE-8200 incorporates a high-precision time stamp that records the elapsed time of transmission or reception at minimal 1-μs intervals from the start of measurement.
This function has widened the range of applications from the narrowing down of data on a specified time-anddate basis to the checking of delicate timing. Moreover, the LE-8200 displays idle time, thus making it possible to check the response time and timeout of transmission or reception at a glance.
In addition, it is possible to judge each frame in asynchronous communications by specifying a non-communications period of 1 to 100 milliseconds or end data.

Long Recording Time Allowing Rolling back to Points of Communications Failures
The LE-8200 has 100MB capture memory that gains high-speed access to megaspeed communications, and is provided with ring and fixed buffer modes.
The user can select the ring buffer mode for endless recording or the fixed buffer mode to stop recording automatically when the memory is full. Furthermore, the LE-8200 incorporates an auto save function that makes it possible to save the monitored content of captured memory on a high-capacity compact flash (CF) card in a specified file size continuously.
This is useful for identifying rare communications failures of unknown causes.
Applicable transmission speed Continuous recording time reference *1
Main memory only 16GB CF card *2
9600bps Approximately 6 hours Approximately 960 hours
1Mbps Approximately 220 seconds Approximately 10 hours
*1) In the case of full-duplex transmission of 1-kilobyte data at 1-millisecond intervals, both transmission and reception data will consume 4-byte memory for each capture.
*2) With the optional CF-16GX used.
Supporting Logic Analyzer Analysis and Analog Waveform Analysis [New Function]
The logic analyzer, which digitally displays the waveforms of communications line timing, operates at
a sampling rate up to as high as 40 MHz. Furthermore, this feature realizes the simultaneous display
of 12 lines by making use of the large-sized screen.
Besides, the adoption of function keys ensures the operation of the time cursor with ease.
Furthermore, if the OP-SB85 optional expansion kit is used, measurement of analog voltage waveforms at a maximum rate of 40M samples per second will be possible.
Therefore, you will be able to realize detailed waveform observation without carrying a heavy general-purpose measuring instrument when you are on a business trip.
These functions help to identify hardware problems.
You can also use it for educational purposes, comparing documents for communications protocol.

Trigger Function with Detection Capability Reinforced Twice [Functional Enhancement]
Trigger 4

Trigger 5
The trigger function controls the operation of measurement when the function detects specific communications status.
Conventional models have four combinations of trigger conditions and trigger actions.
On the other hand, the LE-8200 is provided with eight combinations for ease of making settings that are more flexible.
This function not only enables the detection of eight types of conditions simultaneously but also makes it possible to detect particular conditions in sequence.
Complicated communications events can be precisely grasped.
[Contents of trigger settings]
Trigger 0 External trigger output in case of error generation .
Trigger 1 Saves the data before and after idle time on the CF card when the idle time exceeds the set value.
Trigger 2 Starts timer 0 when the specified signal line is 1.
Trigger 3 Stops timer 0 when the specified signal line is 0.
Trigger 4 Enables trigger 5 when start flags 01h, 02h, 03h, and F1h or 01h, 02h, 03h, and F3h are detected in sequence in SD.
Trigger 5 Stops measurement immediately when 58h, 59h,
5Ah, arbitrary 2-byte data, and the end flag are detected in sequence in RD.
Trigger 6 Stops measurement when timer 0 coincides with the set value.
Voltage Measurement of Communications Line with Ease [New Function]
[Example of analog & delay time measurement]
With the feature of delay time measurement, a period of change of the communications control line from the present state to another can be measured at a 0.1-ms resolution.
The feature is added with a function to measure the maximum, minimum, and present voltage amplitudes of SD, RD, DTR, and external EXT signals over RS-232C.
This allows ease of the voltage amplitude measurement of wiring in connectors where the probes of testers cannot reach smoothly, thus contributing to the investigation of communications trouble caused by an insufficiency in the amplitudes of signals resulting from a circuit voltage drop.
Graphic Display of Hourly Communications Status
[Example of graphical display of statistical analysis]
This statistical analysis feature is used to measure the volume of communications and the number of occurrence times of specific communications status for a specified period ranging from 1 to 240 minutes with the results graphically displayed. Condition 0 and condition 1 of the trigger function can be specified as target items.
Therefore, it is possible to grasp not only the change of communications traffic (the rate of line usage) but also the number of transmission and reception times of specific data strings and the occurrence frequency tendency of errors on a time zone basis.
Furthermore, the auto range display with increased graphic resolution allows ease of seeing slight changes.

Simulation function provides the actual operating environments

[Example of connection for simulation]
With the simulation feature, LINEEYE 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, it provides six types of simulation modes.
Error handling process can be checked by sending data with parity errors. Margins can be evaluated by intentionally shifting communications speed.
For example, test the 9600bps target device at 9840bps speed. In addition, data transmission can be linked with the changes in the signal lines, and an automatic control of RS-485 transmission driver IC is supported.
MANUAL mode
[Data table setup]
The MANUAL mode allows you to send the data registered in transmission table which corresponds to the "0" to "F" keys. The data can be set with one press of a key.
While checking replies from a unit under development with the 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 "D" keys, as well as turn RTS/CTS and DTR/DCD signal lines on/off with the SHIFT and "E"/"F" key combinations.
online demo
BUFFER mode
[BUFFER mode setup]
In the BUFFER mode, you can select between transmission and reception, and send transmitted or 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.
FLOW mode
[FLOW mode setup]
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 16 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.
ECHO mode
[ECHO mode setup]
In the ECHO mode, LINEEYE protocol analyzers internally return received data.
Buffer echo to send back data by a frame, character echo to send back data by a character and loop back echo to return by the hardware can be selected.
It is used to test display terminals and communications terminals.
POLLING mode
[POLLING mode setup]
The POLLING mode simulates the slave and master units in multidrop (1:N connection) polling protocols. In the slave mode, the LINE EYE protocol analyzers 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 32 slave units, and check and display replies from each slave.
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.
[PROGRAM mode setup]
