PC-connectable Communicarions Protocol Analyzer - LE-150L
This model is discontinued. The successor is LE-150PR/LE-200PR.
This entry model is the PC-connectable Communication Protocol Analyzer. It has the Simulation function and the On-line Monitor function to analysis ASYNC communication up to 250Kbps. It has substantial functions (e.g. Continuous HDD Recording), working in cooperation with the PC, offering at a low for every engineers.
Option | Updated Software | Trial Version
The LE-150L is a network-compatible model connected to the PC over Ethernet LAN (10/100BASE-TX). This model makes it possible to measure multiple target lines remotely over LAN communication.

Flexibly Supporting Boud Rates up to 250kbps

Analysis is possible at baud rates from low speed to high speed.*1
For example, a margin test of communication speed is possible at a baud rate of 9,648 bps.
*1: LINEEYE’s patented arbitrary baud rate technology is applied with a maximum setting error of 0.01%.

RS-232C/422/485 Support (Standard feature)

LE-150 Series analyzers come standard with measurement interfaces for the high-use RS-232C and high-speed RS-422/485 standards. With the OP-5M (option) used, it is possible to support TTL-level communication at 2.5, 3.3, and 5 V.

Continuously Records Communication Logs up to 8 Gbytes

LE-150 Series analyzers continuously record measured data on the hard disk of the PC while displaying the data in real time. The continuous recording of measured data in a specified size is possible, thus it is useful for identifying rare communication failures of unknown cause.

Exactly Catching Target Communication Data

LE-150 Series analyzers have a trigger function, with which up to 4 condition settings can be specified in combination with corresponding actions, and precisely captures target data during measurement. The analyzers incorporate a search function as well, thus quickly retrieving and displaying specified data from large quantities of measured and recorded data items and saving the required time of analysis.

Simultaneous Recording of Time Data and Control Line Data

LE-150 Series analyzers can measure data on communications data. The analyzers internally process such data operating system.

Equipped with Simple Simulation Function

LE-150 Series analyzers incorporate an easy-to-use simulation function that makes it possible to transmit preset transmission data (16 types of data with a total of 16 Kbytes) or fixed data, such as FOX messages, at the flip of a switch while checking reception data.

Compact, Lightweight, and Low Power Consumption Design

LE-150 Series analyzers employ an aluminum casing and a highdensity six-layer PCB for a size reduction to a pocketbook size.

Converts Measured Data into Standard Formats

Communication log files can be converted into text or CSV format all at once for use on word processor or spreadsheet. In consideration of analysis on general-purpose search software, it is possible to delete decorative guides or time data, and to specify conversion of sender or receiver data only.
