Compact Protocol Analyzer LE-1100-ECompact Protocol Analyzer LE-1100-ECompact Protocol Analyzer LE-1100-ECompact Protocol Analyzer LE-1100-E
Asynchronous is possible to be monitored up to a max. 115.2 kbps in real-time. PPP(Point-to-Point Protocol), which can be monitored, is frequently used for the internet connection between a PC and a modem . High-performance communications analyzers are capable of monitoring, simulation and BERT. Not only RS-232C of a standard interface but also expandability supports RS-422/485, X.21, V.35, current loop TTL and IrDA with option adapters.

Monitoring

Supports Max. 115.2 kbps of Communication
Asynchronous communication is possible up to a max. 115.2 kbps. Separate speeds can be set for transmission and reception. Online Monitoring
Analysis of Interface Signal Line
Analysis of Interface Signal Line 2-color LEDs indicate (red-green-out) signal high/low level and disconnection, making it easy to confirm cables are connected. Also, using a delay time feature, the change of individual signal lines can be measured in 0.1ms resolutions.
Time Stamp and Idle Time Measurement
The 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 time, measurements can be performed unmanned and the time of errors easily and comfortably checked later. LE-1100-E can also measure the amount of idle time between communications frames and closely monitor transmission/ reception response and communications timeout status
Protocol Translation Display
Each protocol of BSC and PPP is translated and displayed. One-touch switching makes analysis or observation speed up.

PPP translation display
Large 192KB Memory Buffer
Incorporates a large memory buffer for long-term measurement. Other features include a convenient two-dividing ring buffer for comparing data and protection to safeguard data against misoperation or mishandling
Trigger Feature
First of all, two actions will be set up to four pairs. One of them is the action of trigger conditions. The other 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.
Moreover, 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.
Auto-Configuration
Auto-configuration can be analyzed and set such as baud rate and data framing automatically set based on findings. This is effective for monitoring lines of unknown communications conditions.

Simulations

Four Kinds of Simulation Functions
[ MANUAL mode ]
The manual mode helps you 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 series, 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-1100-E 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.
 
Transmission Tables of 8K Data
With a dedicated editor that enables copying, pasting, filling and capturing of sixteen 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
As a standard feature, LE-1100-E comes with a ITU-T G.821-conforming BERT feature. It allows you to evaluate communication 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. BERT Function

Packed with Easy to Use Handy Features

Menu-based Simple Operation
Functions are easily selected from menus.
Off-line Analysis with Searching and Counting
Any range of data saved in the buffer can be scrolled, paged and displayed in units of one character, one line or one page. Also, a formidable search engine makes it possible to search for specific data, errors, time stamps, etc. And, it tells you how many of the search items are found in the buffer. Off-line Analysis with Searching and Counting
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 100 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 display.
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-1100-E much greater
Powerful External Interface Functions
Powerful External Interface Functions Data is displayed on a large LCD and simultaneously stored in memory in real-time. And, still at the same time, the same data can be output via the AUX port to an external device such as a PC, all while monitoring is in progress.
(Need to use of optional PC software <LE-PC200-E>)
