Overview:
The hand-held network packet analyzer is a hand-held smart substation optical digital network analyzer. It is a new product that relies on the rich on-site debugging experience and user communication in Wuhan Guo Electric Net Ningshi, and has been re-designed. It is a substation and the daily maintenance, detection, commissioning, monitoring and analysis equipment of manufacturers. With a new test method, a complete feature gives you a new experience of intelligent substation efficient and convenient testing.

Function:
1. New test mode, perfect feature brings you an efficient and convenient test experience of intelligent substation;
2. Replace the complex selection output SMV, Goose control block process, by selecting the target test equipment, the instrument directly outputs the total datagram (IEC61850 SMV Goose) required to test the target test equipment, and create a new experience of the convenience test;
3. The message is strong, and the optical port can be arbitrarily configured, fully meet the test requirements such as measurement and control, female differences, so that the process layer, the interval device is not tested under the abnormal conditions of the alarm due to insufficient test instrument output, let you Perform accurate and efficient testing;
4. Goose receives and transmits abandoned channel mapping mode, automatically resolves the Chinese name according to the SCD file, and the test results are straight;
5. Compatible with many manufacturers' IED files, support SCD file resolution and detection, and analyze data release, subscription information, and simplify testing process;
6. Support IEC60044-7 / 8 (FT3) sampling value packet transceiver function, optional 2.5Mbps, 5Mbps, 10Mbps transport baud rate;
7. Support multiple SMV packet sample rate settings, support the GOOSE heartbeat packet and the variation time setting;
8. Support IRIG-B and IEEE 1588 mode, provide time synchronization, and view clock source time functions;
9. Support SMV, Goose, IRIG-B, IEEE1588 message monitoring, can be abnormally statistics on the packets. It has a monitoring of remote measuring, telemetry monitoring, and tandem, quantity, etc.
10. Have a GPS calorie signal output function (IRIG-B) for equipment school testing;
11. Support the polarity test of the test light digital voltage, current transformer, transformer;
12. Large screen graphic color LCD display, intuitive interface menu, modular operating properties configuration, information is detailed and intuitive, but the button operation is easy to use.
