Specification
| Applicable Analyzer | LE-8200A/LE-8200 |
|---|---|
| Interface | USB 1.1/2.0 A/B receptacle 1 each |
| Applied speed | HIGH (480Mbps) / FULL (12Mbps) / LOW (1.5Mbps)Automatic detection, Automatic switching |
| Memory capacity | Capture memory of Analyzer is 100MB |
| Record type | Ring buffer or Fixed size buffer |
| Auto save function | On ONLINE Monitor Function automatically saves the monitored USB data as communications log file in the external memory.*1 |
| USB log display | USB Packet : SOF, IN, OUT, SETUP, DATA0, DATA1, ACK, NAK, STALL, PRE, DATA2, PING, MDATA, SPLIT, ERR, NYET, and [Unknown] Bus event : Reset, Suspend, Device disconnect, Device chirp, Hub chirp, OTG Vbus event Translation : Standard device request, Standard device descriptor. Measure VBUS voltage/current simultaneously. |
| Timestamp | Resolution 16.7nsec. for Max. 20 hours Elapsed time and Time between two packets are selectable. |
| Log filter function | Record or not record SOF, IN transactions without IN-DATA, PING transactions, OTG Vbus event, Specific address, and Specific endpoint. |
| Display filter function | Display or hide SOF, Transaction of IN-NAK, SETUP, PING, specific address and specific end point. |
| Trigger function | Able to set 8 trigger conditions(Trigger 0 to 7). Triggers are proceeded in a sequence from Trigger 0. |
| Trigger condition | Errors(CRC and PID errors), Particular address/end points, Packet types(TOKEN and HAND SHAKE packets in combination), Data packets (max 8 bytes from the head of DATA packet's payload), Bus events, VBUS voltage/current, logical state of 4 external signal. |
| Trigger action | Outputs a pulse signal from an external terminal after satisfaction of trigger condition.Stop measurement after satisfaction of the last trigger, repetation of the last trigger condition, continuously logging. |
| Retrieval function | Retrieves the specified frame or events to display and displays the top of data or counts the number of data. |
| VBUS measurement function | Vbus measurement(Dump or Graph(Current,Voltage, Power)) Voltage : 0.00V to +8.00V (Accuracy : ±1% FS) Current : -2000mA to +2000mA*3 (Accuracy : ±2% FS) |
| Change and Printout of Data | USB data can be converted to text files, printed out and saved to external memory.*4 Vbus measured data can be converted to text files and csv files. |
| External input or output pins | 4 TTL level inputs and 4 TTL level outputs Linked with trigger function |
| Accessories | Interface expansion board, Line state sheet D, USB cable, Utility CD |
*1: Able to record up to the capacity of external memory (CF card, USB flash drive). However, it is possible that there is some capturing loss for a large load data, because saving to the external memory cannot be proceeded at the same time.
*2: Translation of various class specific descriptors and device requests will be supported in the future version's up.
*3: About Current, "+" means the current direction from A connector ("HOST") to B connector ("DEVICE") , and "-" means the opposite.
*4: It consumes much time to convert a large USB data into a text file on LE-8200A/LE-8200. In this case, it is recommended to use leucvt_win which is much faster than LE-8200A/LE-8200.
