Auto Save... Long Recording Time

Built-in memory card (PC card) interface	Memory card 8GB
	MC-8GCF

The auto save function makes it possible to continuously save up to 8Gbyte^(*). It automatically saves the content of the capture memory on a high capacity compact flash (CF) card. And it continuously saves data into the measurement log of a user-specified file size, using ring recording as long as the card has space. In addition, it is useful for identifying rare communication failures of the unknown cause.

Logic Analyzer Display

Analyzes timing trouble in bits

Communication line timing is analyzed and displayed as a logic analyzer display to a time resolution of max. 50ns. This function helps to identify the problems with hardware. Also, you can use it as educational use, comparing documents for communications protocol.

< Logic analyzer display > Measurement between the cursors at 12 micro sec.

PC Link

Use measurement data on PC via dedicated application.
Manipulate measurement data on your own PC. By connecting the serial cable, the measurement log is recorded to HDD of a PC ^(*1). Moreover, the record log on a memory card are converted to the text format on a PC ^(*2) to use.

Online Monitoring

The online monitor feature records communications data in the capture memory and provides an easy-to-understand display for the type of protocol, without affecting the communication line. LINE EYE protocol analyzers record not only communications data but the time (time stamp) of transmission and reception as well as idle time. Therefore, failure time and timeout status can be checked. In addition, it is available for the trigger function which detects specific communication conditions and for the recording function to select the specific address frames which helps you to effectively use the memory.
Depending on the test, you can select bit transfer sequence and polarity, as well as modulation format from NRZ, NRZI, FMO, FM1 and 4PPM. The feature allows to support effective analysis by omitting SYN codes and using SDLC/HDLC address filter.

Time Stamp Measurement

Record the data and the time of transmission / reception for data frames. ASYNC cannot recognize the length of frame. Thus, our analyzers decide the frame end when it find the specific character, or when it pass the specific time of being non-communication. Time stamp will be displayed in above 2 situations.
* Specifies OFF, day / hour / minute, hour / minute / second, or minute / second / 10msec.
Non-communication state which works as the frame end detection time of ASYNC and Burst communications can be set from 1 to 100ms.
* The example indicates that received time of last data was 20min. 56.37sec(M / S / 10mS setting)
* If there are some frame with same time stamp, it is because the analyzer measured the frames in 10ms. (example : start from 20Mitute 56Second 370ms and 20Mitute 56Second 379ms)

Idle Time Measurement

The amount of idle time between communications frames can be measured.
* Specifies OFF or a resolution of 100msec., 10msec. or 1msec.
* The example indicates there was an idle time of 7 to 7.9ms(1mS setting)

Trigger Function

The trigger feature allows you to specify a communications event as the trigger condition and have measurement operations executed automatically when that condition is specified. 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 a trigger condition can be specified as the condition for another trigger, making it possible to analyze complicated operations based on sequential trigger. Trigger Event Communications error (individual error type can be specified), communications data string of max. 8 characters (DON'T CARE and bit mask cab also be specified), logic status of interface signal line, matching to timer / counter value, idle time beyond a specified duration, external trigger input Trigger Operation Buzzer sounding, measurement recording stop (offset can be specified), save monitor data on memory cards (the range can be specified), timer control (start, stop, and restart), counter control (count and clear), trigger condition activation, transmission of specified text string (in MANUAL simulation)

Statistical Analysis Measurement

< Statistically analyzed data >

Statistic can be compiled for transmission and reception data sets, frames and the number of established trigger events, and subsequently displayed as a graph (Unit: 1 to 240min.). This helps to understand communications traffic and error frequency for a specific time period.

Monitor Condition Auto Setting

Communications data received is analyzed. And the following basic measurement conditions are automatically set based on the findings: communication speed, the character framing, data code, SYNC character, BCC/FCS, etc.

Delay Time Measurement

Enables to measure min. / max. / average time of until some signal state is changed to another state and the number of its times. It is useful for delay analysis of control line RTS-CTS and so on.

Simulations

With the simulation feature, LINE EYE 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, tests can be run at near to actual operatingstatus. After performing the step-by-step check of the communications protocol in the analyzer's ownoriginal MANUAL mode, the developer can create a simple program to branch conditions using the menu selection and test more complicated communications protocols.
Communications speed can be freely set. Therefore, margins can be evaluated by intentionally shifting communications speed, and error response processing can be checked using test data that mixes in data with parity errors.

< Control lines and data transmission timing >

MANUAL Mode

The manual mode allows you to send data registered in the transmission table which corresponds to the "0" to the "F" keys. Data can be sent with the press of a key. While checking replies from a unit under development with the analyzer's monitoring feature, 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 the "D" keys, as well as turn RS and ER signal lines on/off with the SHIFT and the "E"/"F" key combinations.

< Transmission table setup display >

FLOW Mode

Flow control can be simulated on the transmission and reception-lines using X-on/off flow control or the control line handshake. In the transmission mode, up to sixteen cycles of data from transmission start until a generated interrupt request can be displayed. In the reception mode, you can set the number of received data cycles until a transmission interrupt request is generated, as well as the time until the transmission resume request is generated.

< Flow mode setup display >

ECHO Mode

In the echo mode, the analyzer internally return received data in units of bits, bytes or frames (character string). It is used to test display terminals and communications terminals, and to set loop-back points for the BERT feature.

POLLING Mode

The polling mode simulates the slave and master units in multidrop (1:N connection) polling protocols. In the slave mode, the analyzer check the number of received frames that are assigned their address and whether errors occur or not, replying with user-set data. In the master mode, they send polling messages to thirty two slave units, and check and display replies from each slave.

< Polling setup >

BUFFER Mode

In the buffer mode, you can select transmission or reception, and send transmitted and 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.

< Buffer data reproduction setup >

PROGRAM Mode

By creating a purpose-specific command program, the communications protocol can be flexibly simulated alongside condition monitoring. The program is created using the menu selection, so it is easy to master.

BERT(Bit Error Rate Test)

BERT support enables you to measure transmission quality of communications lines by a loop-back or interactive connection. It is possible to measure evaluation parameters (bit error count, block error count) conforming to ITU-T G.821 Notification, hence enabling bit error rate evaluations and fault point identification. Elaborate test patterns and functions such as bit error forced interrupt are comparable to dedicated equipment.

< BERT display > This function allows to analyze in the ASYNC or SYNC mode by selecting test mode (CONTINUE, R-BIT, RUN TIME and Repeat) and test patterns. < BERT measurement display > Starting measurement updates the measured results of line quality in real time. With REPEAT mode, you can know the bit error rate of every specific time on a communication circuit.

PC Compatible File Management Specification

Test conditions and results such as measured data can be saved on microdrives, compact flash cards and other memory cards in the file management format compatible with your PC. Of course, files can be interchangeably used between models such as LE-7200-E, LE-3200-E, LE-2200-E, and LE-1200-E. Therefore, measurement data can be saved on-site with LE-3200-E, and analyzed or manipulated in greater detail using LE-7200-E back in the office.
* Not available to use memory cards for LE-1100-E.

This function allows you to check files saved into memory cards by type, name, size, and/or date.
