LINEEYE RS-232C/ RS-422/ RS-485 protocol analyzer “LE-2500-E” measures ASYNC/SYNC communication. It has the sufficient measuring functions, such as line monitor function for RS-232C/RS-422/RS-485 interfaces, simulation function and Bit Error Rate function. Also, it has the arbitrary speed setting, logic analyzer function and Auto save function without any options. The optional PC link software “LE-PC300G” enhances the link between the analyzer and PC to have a remote control. This device can be used for anyone and not only for engineers. It is the useful for maintenance purpose because it can run by the battery, and it is easy to carry using the provided carrying bag. Key Features *Measure up to 1.000Mbps. Speed is freely set to 4 effective digits. *Support RS-232C/422/485 without any options.

Mega Speed MeasurementYou can test measurement of high-speed communications up to 1.000Mbps (half duplex and full duplex). Using high precision DPLL technology for open baud rate support, transmission and reception speeds can be separately set to an effective 4 digits. Multi-Protocol Support LE-2500 comes standard with measurement interface for RS-232C (V.24) and RS-422/485 (RS-530) standards. X.25, RS-449 and V.35 require only a dedicated cable. *Expansion kits supports TTL, I2C, IrDA, CAN and LIN Protocols of differing hardware specifications are supported by simply changing the measurement boards. Auto Save... Long Recording Time 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 Analysis And Signal Voltage Measurement Communication line timing is analyzed and displayed as a logic analyzer display to a time resolution of max. 50ns. The new function of signal voltage measurement ensures ease of the voltage measurement of RS-232C signals in places where tester probes cannot reach smoothly. PC Link The LE-PC300G supports serial connections through the COM port, USB connections, and LAN connections via LINEEYE SI-60 converter, thus enabling remote measurement by multiple analyzers connected at the same time. It also allows you to browse measurement data saved in memory card and convert data. 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 communications line. The analyzer records not only communications data but the time (time stamp) of transmissions and receptions as well as idle time. Therefore, failure time and timeout status can be checked. The trigger function detects the specific conditions and you can select bit transfer sequence and polarity, depending on the test. Display special data items in individual signs. Uncommon data status in the communication line is expressed in individual signs. Line State LED communications line state is indicated in real time using 2-color LEDs 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 finds the specific character, or when it passes the specific time of being non-communication. Time stamp will be displayed in above 2 situations. Idle Time Measurement The amount of idle time between communications frames can be measured. 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. Monitor Condition Auto Setting The analyzers can analyze communications data and automatically set basic measuring conditions, such as communications speed, character framing, data code, synchronization character, BCC/FCS, etc. This is effective for monitoring lines of unknown communications conditions. Delay Time Measurement A feature to measure the voltage of four RS-232C signal lines has been added to the conventional delay time function used to analyze the delay time of control line changes (e.g., RTS to CTS changes) at a resolution of 0.1ms. Simulations With the simulation feature, the the analyzer acts as the counterpart to the target device and performs 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 operating status. MANUAL mode checks the communications protocol step by step. 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. *MANUAL Mode *FLOW Mode *ECHO Mode 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. Menu-Based Simple Operation Anyone can easily operate the analyzer owing to the easy menu selection system handed down from earlier models.
