Supports Max. 115.2 kbps of Communication
MonitoringAsynchronous and synchronous communications are possible up to a max. 115.2 kbps.
Separate speeds can be set for transmission and reception.
Multiple Protocol Support
Multiple Protocol Support

LE-3100 supports the following protocols; ASYNC, SYNC, BSC, SDLC(NRZ/NRZI), HDLC(NRZ/NRZI) and packet communications(ITU-T X.25).

Multiple Protocol SupportAlso, X.25level2(frame level), level3(packet level), SDLC translation display, BSC translation display and PPP translation display are supported. One-touch switching makes analysis or observation speed up.
Analysis of Interface Signal Line
Line State2-color LEDs indicate (red- green- out) signal high/low level and disconnection, making it easy to confirm cables are connected.
Also, using delay time feature, the change of individual signal lines can be measured in 0.1ms resolutions.

Analysis of Interface Signal Line
Time Stamp and Idle Time Measurement
Time Stamp and Idle Time MeasurementThe data and time of transmission/ reception are recorded on data frames. Then, using an auto run-stop feature with which the user specifies measurement start and end times, measurements can be performed unmanned and the time of errors easily and comfortably checked later. LE-3100 can also measure the amount of idle time between communications frames and closely monitor transmission/reception response and communications timeout status.
Large Memory Buffer
Large Memory BufferIncorporates a large memory buffer for long-term measurement. In the buffer mode, a loaded card acts as expanded memory space, boosting storage area to a mix. 1.2MB. 2-dividing ring buffer for com paring data and protection to safeguard data against misoperation or mishandling.
Trigger Feature
Trigger FeatureFirst of all, two actions will be set up to four pairs. One of them is the action of trigger conditions. The other is it of when the conditions are satisfied. And then, the followings will be able to performed under the conditions of specific data string receipt (Max. eight characters), error occurrences, interface signal line changes and etc; automatic stop of monitoring, timer/counter control and etc.
Trigger FeatureMoreover, the timer/counter function with the trigger function allows you to be able to measure specific data, the number of error occurrence, and response time from transmission and reception sequence. As a result of that, the clarification of intermittent troubles will be performed effectively.
Data on the communications line can be analyzed. And settins such as baud rate and data framing automatically set based on findings. This is effective for monitoring lines of unknown communications conditions.
Statistical Analysis Capabilities
Statistical Analysis Capabilities The number of occurrences of a selected target event (data, packet, specific type of error, etc.) can be tabulated for a unit time and plotted on a graph. It makes it possible to accurately identify the changes in traffic in specific time periods(line use frequency) and the time distribution of errors.


Seven Kinds of Simulation Functions
[ MANUAL mode ]
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 sent with the press of a key. While checking replies from a unit under development with the monitoring feature of LE-3100, 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 RS and ER signal lines on/off with the SHIFT and "E"/"F" key combinations.
[ MATCH mode ]
In the MATCH mode, when "SEND" is selected as the trigger action and that condition is satisfied, registered data can be sent after a set amount of reply time elapses. By triggering a reply transmission with a specific type of data or error as the trigger condition, timeout processing and error response operations can be easily checked.
[ FLOW mode ]
Flow control can be simulated on the transmission and reception-lines using X-on/off flow control or the control line handshake.
[ ECHO mode ]
In the ECHO mode, LE-3100 internally returns received data in units of bits, bytes or frames (character string). It is used to test display terminals and communications terminals, and to set loopback points for the BERT feature.
[ POLLING mode ]
The POLLING mode simulates the slave and master units in multidrop(1:N connection) polling protocols. You can easily test complicated POLLING system.
[ Buffer mode ]
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.
[ PROGRAM mode ]
The PROGRAM mode flexibly simulates communications protocols by letting the user program operations with purpose-specific commands selected from menus.
Transmission Tables of 8K Data
With a dedicated editor that enables copying, pasting, filling and capturing of 16 types of transmission data, data can be registered in transmission tables and used in the various modes.

BERT(Bit Error Rate Test)

Max. 115.2kbps BERT
Max. 115.2kbps BERTAs a standard feature, LE-3100 comes with a ITU-T G.821-conforming BERT feature. It allows you to evaluate communications quality and identify fault points on communications lines, including modern and terminal adapters, in loopback tests and comparison tests using a simulated random pattern. It provides capabilities comparable to purpose-specific hardware, such as bit error interrupts by key operation, long continuous measurement, as well as measurement results print out and electronic output.Max. 115.2kbps BERT

Built-in Memory Card Interface
A memory card can be used in two modes; a file mode and a buffer mode. In the file mode, it is capable of storing up to a hundred files of setting information or monitored data. Since the saved data can be recorded, it is possible to be used more effectively; the date, time and the file name. In the buffer mode, it expands the capacity of the buffer memory.
Data Printing
Users can print out measurement data of a user-specified range in a continuous format. And, with a dedicated printer, it is possible to make hard copies of windows® just as they appear on the monitor.
Superb Extensibility
The use of optional interface adapters allows you to correspond to the various interface except RS-232C (V.24), which makes the rich functions of LE-3100 much greater.
