model	characteristic	Input the number of streams
DT-100 rack type	Adopting a 1U industrial control computer, suitable for shelving in the computer room, supporting all the testing functions listed	1/4 optional
DT-200 Portable Type	Same function as DT-100 model, convenient for engineering personnel to carry with them	1/4 optional
DT-800 Network Type	In addition to all the testing functions of the DT-100 model, it also has powerful network monitoring capabilities, which can perform real-time monitoring and analysis of all stream transmission sites through the network. The unique electronic map function facilitates the positioning of all monitoring points. Once the monitoring instrument of a certain site detects an error, the corresponding icon on the map will immediately issue an alarm.	1/4 optional (Only referring to one agent)

Testing function:
Stream tree structure - lists the programs contained in the stream, PID and PSI information contained in each program, SI information, etc. in a tree like structure.  
Basic information - provide stream number, PID number, program number, network number, network name, stream bit rate, bit rate allocation map, as well as stream ID, network ID, network original ID and other information.

Program information - including program information and program segment information. Program information includes program ID, program name, program provider name, program mapping table PMT PID, program reference clock PCR PID, whether the program is encrypted, whether the program is currently being played, and the type of program being played; The program time segment information includes program segment EIT PID, program segment name, encryption status, start time, duration, operating status, language, and program segment description.  
PES stream information - including basic stream PES ID, basic stream type, program ID, packet count statistics, transmission bit rate, stream identification ID, PES packet prefix, PES packet length, as well as some flags such as PES scrambling flag, copyright flag, etc.  
PSI/SI information - provides the PSI and SI table types contained in the stream, as well as the corresponding IDs, packet numbers, and transmission rates for each table.  
TR 101 290- According to the ETSI TR 101 290 standard, real-time dynamic monitoring, statistical analysis of third level errors in the stream, and generation of error logs.  
PCR measurement - online dynamic tracking of PCR transmission characteristics and display of measurement results.  
Bit rate - provides analysis of the bit rate and bandwidth allocation for TS streams.  
Stream recording configuration - provides two ways to trigger stream recording: time and event, facilitating subsequent offline analysis.  
Stream playback - used for stream analysis in offline mode.  
Syntax analysis - Track and capture the PID type specified by the user, and then perform a detailed analysis of the captured TS packets, including TS transport stream header analysis, PES basic stream header analysis, PT private table syntax analysis, and PSI/SI information table syntax analysis.  
PsiSi structure - displays information from PSI and SI tables in the form of a tree diagram.  
Buffer analysis - provides the current working status of all program buffers, divided into three categories: video, audio, and system buffers. Each category is further divided into transmission buffer and main buffer, and each buffer lists the type, capacity, and current occupancy percentage.  
Wired front-end physical layer testing - including signal power, spectrum scanning, constellation diagram MER、 Bit Error Rate Test.
