The firmware is preinstalled, and by simply replacing the interface board, it can be used as a standalone analyzer that supports in-vehicle communication and analog measurement.

Continuous measurement recording and real-time display of 2-channel CAN/CANFD communication data, up to 8 analog signals, and GPS positioning data with time stamps are possible.
Analog signals can be input via an analog pod connected to the extended analog measurement port or from the high-speed analog measurement port.

CAN (CAN FD) measurement port pin assignment

External trigger/extended analog measurement port (pin header 10 pins 2.54mm pitch)

This connector connects the included analog pod OP-8AH and optional analog pod OP-8AT. You can also use the TRG.IN and TRG.OUT terminals to input and output external triggers.

Connect the analyzer's measurement port to the line to be measured using the attached cable.

With the optional OBD2-DSUB9 cable, you can easily connect the Ch1 to an OBD2 connector of a car.

It can execute the online monitoring recording CAN/CAN FD communication frames with a communication speed of 20kbps to 5Mbps in the capture memory with time stamps of the resolution of 1µ second. Communication data is acquired by the measurement FPGA, so unlike CAN monitors using CAN controller ICs that cannot display ACK error frames, all communication frames are accurately captured and displayed.

You can check the timestamp, channel, ID, communication frame type, data length (DLC), communication frame status (St), data (in hexadecimal), and CRC value (FC).

Data of various IDs flow on a line that connects many nodes. By setting an ID filter and narrowing down the IDs of communication nodes to be investigated, analysis efficiency will be greatly improved.

Measurement can be performed by specifying up to 8 sets of conditions and measurement operations after the conditions are met. It can be used as a sequential trigger to automatically stop measurement when a specific data frame is received, or to enable another trigger condition when one trigger condition is met, making it extremely useful for intermittent failure analysis.

Communication error occurrence, specific data reception, remote frame reception, timer/counter value matching, and external trigger input can be specified as the trigger factor.

When a trigger is met, the following actions can be specified: buzzer sound, measurement stop, data saving before and after the trigger, timer/counter operation, enable/disable specified trigger, CAN frame transmission, external trigger output, etc.

When the target device is not available at the early stage of development, this device can act as a communication partner for the device under test and send CAN/CAN FD test frames.

The 16 types of main data tables correspond to the [0]-[F] keys on the main unit and you can send test frames with one touch. Pre-registered data frames and remote frames in the standard format / extended format can be sent simultaneously at any cycle.

It can specify a sweep that automatically changes part of the communication data at an arbitrary rate of change. This is useful when checking how the behavior of the actuator under test changes in response to changes in communication data.

[ Relationship between target value and time ]

Each main data table has 16 sub-tables, allowing group transmission with a single keystroke. In addition to the same settings as the main table, the sub-table has additional transmission ON/OFF settings and "delay time" settings, and depending on the settings, periodic transmission as shown below is possible.

The 2-channel analog voltage waveform measurement function supports up to 100M samples/sec and ±24V. You can easily observe detailed waveforms at sight without bringing out heavy general-purpose measuring instruments.

In addition to voltage rising/falling edges, waveforms can be acquired by CAN communication measurement triggers. This is useful for investigating the cause of rare problems. In addition, it can be connected internally to the differential communication line of the CAN communication measurement port (Ch1), allowing detailed observation of CAN (CAN FD) communication signals without pulling out a line for a probe. It is ideal not only for investigating hardware problems but also for educational purposes related to data communications.

The 2ch input of the BNC analog measurement port can be used for analog measurement even on a standalone board, but by connecting the included analog pod "OP-8AH" to the expansion pod connector, the analog measurement function is further enhanced and it can be used as an 8ch voltage logger.

Connect the cable and OP-8AH to the expansion pod connector EXT.(to POD).

Input up to 8 channels of analog signals to OP-8AH. GND is common.

The measurement range can be set to a maximum of +-60V, and the measurement cycle can be set to a maximum of 62.5µ seconds (16kSPS). Measured values are displayed graphically in real time.

The optional analog pod OP-8AT supports not only voltage but also 4-20mA current measurement and temperature measurement using thermocouples. Analog signals with different ground potentials can be measured with high accuracy [e.g. ±(0.05% rdg + 2mV): 10V range].

By reading DBC files (.dbc), which are widely used to describe CAN translation definitions, you can translate and display information such as physical quantities contained in CAN / CAN FD frames.
In addition, translated values ​​can be displayed in graphs in real time. Up to 8 signals can be drawn simultaneously in combination with the normal analog measurement graph display (either BNC analog measurement port / measurement pod OP-8AH / measurement pod OP-8AT).

The physical quantities included in the CAN/CAN FD frame and analog measured values ​​such as voltage, current, and temperature can be confirmed and compared in real time on the main display, making it ideal for in-vehicle testing, etc.

CAN/CAN FD communication measurement data and analog measurement (logger) function data are recorded in the built-in 1GB large-capacity capture memory. You can choose between a ring buffer mode that allows endless recording and a fixed buffer mode that automatically stops when the memory is full. Additionally, using the auto-save function, you can continuously save the contents of the capture memory being monitored in specified file size units to a large-capacity external storage device. It will be useful in solving unexplained communication failures that occur only rarely.

By connecting an optional GPS antenna, location information can also be recorded. It can be recorded for long periods of time together with CAN (CAN FD) communication data and analog measurement data, making it useful for driving tests, etc.
Multi-GNSS (GPS, QZSS, GLONASS, Galileo, BeiDou) compatible. It supports Michibiki (Quasi-Zenith Satellite System/QZSS) submeter-level positioning augmentation service (SLAS), enabling highly accurate positioning.

The time stamp of this device at the recording time (for comparison with communication data, etc.), UTC time, reception status, number of satellites used for positioning, latitude, longitude, horizontal estimation error, and changes in altitude above sea level are displayed in real time on the measurement screen.

Display of reception status (St)

Since the PPS signal for time synchronization can be output from this unit to which the GPS antenna is connected, by connecting a second analyzer with an SMA coaxial cable (sold separately), simultaneous measurement of two analyzers with synchronized time stamps is possible. A different type of measurement board can be used as the second unit, for example, synchronous measurement with the LE-8500X-SE, which supports in-vehicle LAN communication, is possible.

By pressing [SHIFT] + [ESC], you can take a screenshot of the screen display image of the measurement results / setting conditions and save it as a PNG file. You can also convert measurement data to a text file on the instrument and save it to a storage device, which is useful for making reports of test results. Analog measurement data can also be saved in CSV format. GNSS positioning data can also be saved in KML format. In addition, by connecting a dedicated printer, you can continuously print out a specified range of measurement data or print out a hard copy of the screen display image, which can be used as a recorded memo on site.
