Specifications

Auto Tracking of High-speed USB Transmission

Without affecting the communication line carrying data between the analyzer and target devices, the LE-620HS and LE-610FS internally record large amounts of data and simultaneously transfer it to a connected PC via USB. The analyzers automatically detect the speed of the target devices (12/1.5 Mbps), so a speed setting is unnecessary. And if the device is connected through a hub of differing speed, measurement can be started by simply pressing the space bar of the PC.

Continuous Repetitive Recording of Measurement Data on HDD

Measurement data captured by the analyzer is continuously transferred to the PC for analysis via USB port and recorded as a log file with a maximum of 2 GB on the hard disk of the PC. Furthermore, it is possible to form a ring buffer to record multiple log files continuously by using repetitive recording mode. The measurement log data can be displayed and scrolled during measurement, which is effective for an extended analysis of rare communication trouble under indefinite conditions.

Log file size	Number of log files while in repeat mode	Maximum recording capacity
1 to 2,048 Mbytes	2 to 5	10 Gbytes

Clearly Detailed Monitor Display

USB packets are clearly displayed by transaction. The LE-620HS can identify PING and the split transaction at high speed. Standard requests and descriptors are translated and displayed in detail, therefore the difficult-to-understand USB protocols can be intuitively understood. And, the LE-620HS supports a wide range of device-specific descriptors.

Note : The above screen is a display example of the LE-620HS. The LE-610FS is basically the same as the LE-620HS in display except the display of high-speed transfer, which is enabled by the LE-620HS only.

1. Multiple packets are grouped and displayed on a single line by transaction.
2. Only the first 8 bytes of data packets are displayed. Clicking the [+] mark displays all data.
3. The selected transaction is highlighted with the operation of the mouse.
4. The USB state (i.e., the bus reset, suspend, or disconnection state) is recorded and displayed along with communication data.
5. The target transaction can be marked with 1 to 99, and can jump to the marked positions.
6. Displays the SOF (Start of Frame) frame number. At high speed, microframes are displayed as (1/8) to (8/8). At low speed, nothing is displayed in this column because no SOF packets are generated.
7. Records and displays the time stamp at a resolution of 16.7 ns.
8. Visibility of continuous NAK packets is improved by displaying only those cycles.
9. Displays the details of each transaction and frame.

10. Clicking the [>>] mark displays a detailed translation window of the device request. Descriptors are displayed as a tree view to show their hierarchical structure.
11. When a device request item is selected for transaction, the corresponding data in the
    data packet is highlighted.

1. Displays the content / meaning of device request.
2. Displays the DATA packets in ASCII.
3. Opens the device request window by clicking >> mark on the display.
   The shape of tree shows the layerde stracture of a descriptor.
4. Blinks the corresponding data in the data packet by selecting the item of the device request window.

Device Request Window

1. Button for opening and closing the tree.
2. Button for copying the contents of the Device Request/Descriptor to the clip board.
3. Button for displaying the previous/next Device Request.
4. Button for pinning the Device Request on the screen.
5. Button for adjusting the depth of the color.

Highly Accurata Time Stamp Function

The built-in hardware timer of the analyzer records the time stamps at the packet start and end at a resolution of 16.7 ns based on the log start point as a reference point*1. The time stamps are displayed in the elapse time column and packet position bar. If the cursor points the packet, the time stamps are displayed on the tool tip window as well. *1 The time stamp count is reset to zero approximately five hours after the start of the log and the time stamp count is continued.

Real-time Filter

The real-time filter reduces the quantity of log file data and improves the efficiency of analysis. It is possible to specify not to capture continuous NAK response transaction such as IN-NAK and OUT-NAK. And can specify particular addresses and end points under AND condition in order to record only transactions which meet the condition, or to eliminate them from the targets of recording.

Powerful Sequential Trigger

It is possible to specify up to 16 trigger conditions (e.g., trigger conditions of particular transfer data and external signal conditions) in combination with actions to be taken at the time the conditions are satisfied, and execute the actions in sequence. Furthermore, this feature enables logging control in synchronization with external signals and linking with other measuring instruments by turning an external trigger signal on detection of particular data, thus making significant improvement in the efficiency of program development.

Upgraded Off-Line Analysis Capability

Data can be easily found amongst the huge volume of recorded data by using the filter and search features. Development efficiency is boosted to a higher level by using color-coded customization features for packet types and mark/jump features.

Statistical Infomation Function

It is possible to total and check the number of transactions, the number of transfer bytes, and the average transfer rate in the measurement log. The totaling range can be specified with the mouse or the mark feature. The results of totaling can be pasted to the table calculation software through the clipboard.

Target area

Entire transactions/packets     Totals all the measured data. Selected     Displays this choice only when     transactions are selected. Mark * - *     Displays [Mark * - *] only when     transactions are marked.

Displaying/Hiding the Packets

You can display or hide each type of the packets from the pop-up menu which appears by right-clicking on each item of the packets.

Copying data to the spreadsheet applications By selecting the necessary range and copying it to the clipboard with the Ctrl and C keys, you can paste it to another application such as Excel.

Arranging data Clicking the head of the table helps arrange data in ascending or descending order. Initial screen Ascending Descending

Effective Use of Data Saved in Text File Format

Users can copy, paste, and save selected ranges of measured data as compact text files. The files can be attached to reports or e-mailed to experts for professional analysis.

Expandable FPGA Firmware

Users can download the up-to-date version of the analysis software and firmware for the analyzer and keep the analyzer installed with the latest applications. Furthermore, the analysis software downloaded can be used as view software, thus it is possible to display measured data in detail on multiple PCs without connecting the analyzer.
