5.7-inch Large-sized Color TFT LCD

The large-sized LCD is an easy-to-understand color display showing a flow of communications protocol and data transmitted or received, thus greatly improving the efficiency of measurement data analysis.

 

 

 

 

 

 

 

 

Supports TTL, I2C, SPI, IrDA, CAN ,LIN, FlexRay and LAN

Supports various types of communications protocols widely used over RS-232C/422/485. Also supports new communications standards by exchanging the measurement board.

The monitor function exactly records and visualizes communications data

The line monitor function allows the recording of communications data and provides an easy-to-understand large-sized display without affecting the communications lines. This function makes it possible to grasp the conditions of transmission and reception, thus greatly shortening the required time of troubleshooting. As a standard feature, the LE-8200 supports a variety of communications standards, such as binary synchronous communications (BSC) for character-synchronous transmission, and high-level data link control (HDLC) for bit-synchronous transmission as well as asynchronous communications that are widely used for PC peripheral and microcontroller applications. By adding an optional expansion kit, the LE-8200 will support many more communications standards.

Display of Two Divided Areas for Ease of Comparison

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

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

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 Failure

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.

 

Supporting Logic Analyzer Analysis and Analog Waveform Analysis

The logic analyzer, which digitally displays the waveforms of communications line timing, operates at a sampling rate up to as high as 100 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-SB85L 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

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.

Voltage Measurement of Communications Line with Ease

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

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 (1-240 min. or 1-240 sec.) 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 environment

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.You can select from MANUAL, FLOW, BUFFER, ECHO, POLLING and PROGRAM modes.

BERT(Bit Error Rate Test)

BERT function enables you to evaluate parameters (bit error count, block error count) conforming to ITU-T G.821 Notification, hence enabling error rate evaluation and fault point identification. Elaborate test patterns and functions such as bit error forced interrupt are comparable to dedicated equipment.
