Greatly Improved Basic Performance

Supports Max. 1.544 Mbps Communications

With user-set baud rate support, LE-7000 shamlessly covers the full span of communications speeds from low to a max. 1.544Mbps. Transmission and reception can be tested at both the standard baud rate of the target system and baud rates deliberately set higher or lower than that, giving you easy means of margin testing for baud rate differential.

	Synchronous	1.000Mbps	1.544Mbps
Trigger function fully used	Asynchronous	1.480Mbps	1.544Mbps
	Synchronous	0.750bps	1.544Mbps

Supports RS-232C and RS-422/485

LE-7000 comes standards with measurement interfaces for the RS-232C (V.24) and RS-422/485 (X.20/21) standards that are widely used in communications networks. By simply replacing the board in the measurement unit, you can adapt LE-7000 to the communications standard of other hardware.

High-capacity 3.6 MB Capture Buffer

LE-7000 incorporates a high-capacity memory to enable long measurements of high-speed communications. It can capture a max. 1.8MB of transmission/ reception data. The buffer can also be partitioned into two areas, making it easier to compare captured data. And, your valuable data is safeguarded against misoperation with a protect feature, and it can be retained intact for over two years because of a built-in lithium battery.

Supports multiple protocols

As a standard feature, LE-7000 supports numerous communications standards from asynchronous to packet switching systems. Settings can be minutely tailored to test conditions, including bit transmission sequence and polarity, and NRZ/NRZI modulation format.
Capture efficiency has also been greatly improved with user settings for omitting the second and subsequent SYN codes in BSC, and selective recording of specific address frames in SDLC/HDLC. Moreover, LE-7000 supports analysis work from every direction with support for all kinds of data codes including hexadecimal, real-time data display and protocol translation display, and one-touch switching between interface signal line timing displays.

Time Stamp and Idle Time Measurement

The data and time of transmission/ reception are recorded on data frames in the least resolution of 10ms. 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-7000 can also measure the amount of idle time between communications frames in minimum increments of 1ms and closely monitor transmission/reception response and communications timeout status.

Trigger Feature

The trigger feature helps you specify a communications event as the trigger condition and have measurement operations executed automatically when that condition is satisfied. 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 one trigger condition can be specified as the condition for another trigger, making it possible to analyze complicated operations based on sequential triggers.

Proven Simulation Capabilities

[ MANUAL mode ]

The MANUAL mode allows 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 featuer of LE-7000, you can easily and simply test the communications process. You can send the registered data in transmission table with "0" to "F" keys and the fixed registered data by a key combination of the SHIFT and "0" to "D" keys. You can also turn RS and ER signal lines on/off with the SHIFT and "E"/"F" key combinations.

[ 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 budder 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. So the PROGRAM mode can be used right away. < PROGRAM mode setup display example >

[PROGRAM mode commands example]

Command Operation SEND CHR Sends max. 8 data sets. SEND REG   Sends data registered in transmission table under specified REG No. WAIT CHR          Waits until receiving specified data (max. 8 data sets). WAIT FRM Waits until receiving 1 frame. WAIT TM      Waits for specified amount of time. GOTO L    Jumps to specified label No. CALL L    Jumps to subroutine of specified label No. IF CHR          L    Branched if specified data in reception buffer. IF LN    L    Branches if interface line is specified logic. SET REG          Sets or increases/decreases value of specified REG No. SET TM         L    Controls specified timer and sets to specified value. INT TRG 0 L    Interrupts specified label when trigger 0 condition is satisfied.

Enables Error Interrupt Simulation

LE-7000 comes standard with simulation capabilities effective for communications system development and testing stages. It helps you switch its internal pin array between DTE/DCE in line with contact pin array specifications of the target equipment, so you can efficiently check transmission/reception exchanges. With a dedicated editor that enables copying, pasting, filling and capturing of sixteen types (a total of 16K) of transmission data, data can be registered in transmission tables and used in the various modes. The part of the transmitted data can be saved as parity errors, which makes it possible to check response to erroneous data.

Real Bert Feature

As a standard feature, LE-7000 comes with a ITU- T G.821-conforming BERT featuer. It helps you evaluate communications quality and identify fault points on communications lines, including modems and terminal adapters, in loopback tests and comparison tests using a simulated random pattern up to 2.048Mbps. It provides capabilities comparable to purpose- specific hardware, such as bit error interrupts by key operation, long continuous measurement, as well as measurement results printout electronic output.

Packed with Easy to Use Handy Features

Menu-based Simple Operation

Functions are easily selected from the menu. And, a large packlit LCD makes it easy to view measurement data at night and in dark places.

High-capacity Memory Card Support

Using the optional memory card helps you save up to hundred measurement results and parameter settings. The data and time that the data was saved as well as the file name can be recorded so that data can be used more effectively. And, you can continuously monitor and save a specified range of captured data on memory cards using the trigger feature.

Supports Continuous Format Printing

You can specify a necessary range of measurement data and print out that data in continuous format using the option printer. And, if LE-7000 supports the escape code of your printer, you can make hard copies of screen just as they appear on the display.

Supports RS-232C and RS-422/485

LE-7000 comes standards with measurement interfaces for RS-232C(v.24) and RS-422/485(X.20/21) standards that are widely used in communications networks. By simply replacing the board in the measurement unit, you can adapt LE-7000 to the communications standard of other hardware.

Manipulate Data and Update System on PC

Using the application provided standard with LE-7000, you can upload and save measurement data as text files on a PC. And, the optional application, LE-PC100, helps you save the data as bmp. files in a PC, just as they appear on the monitor. Reports are, then, easily created with a general editor or word processing application. Moreover, the system comes with a ROM rewriting program. With it, you can download the latest version of software from our web site to take advantage of the latest functions and featuers.

Autosave into 64MB Memory Card

The "AUTOSAVE" function is to save the monitored data automatically in a memory card.
The autosave function makes it possible to save the monitored data of every 3.75Mbyte (equal to 960K data) into the file.
The autosaved data can be checked and analyzed by loading the data into a capture memory with file management functions of LE-7000.
Using the 64MB memory card (MC-64MA) helps you save up to large monitored data of 32M.
