R&S^®ETX-T DTV Monitoring Receiver

Realtime monitoring, demodulation and analysis of DVB-T signals via LAN

Features

Remote monitoring via HTTP

Server structure and access rights

For in-depth RF and MPEG2 analysis, the user can access the embedded HTTP server by entering the TCP/IP address of the R&S ETX-T. The user then has access to the R&S ETX-T according to the rights defined by the administrator. The access rights to the R&S ETX-T are classified as follows:

Super User: administration rights only. Highest right access. Can define/modify/delete rights of administrators, maintenance users, operators, query users and cancel active sessions.
Administrator: administrator rights only. Can define/modify/delete rights of maintenance users, operators and query users.
Maintenance User: has access to all settings, thresholds, measurements and monitoring functions (error reports and history function). Only one maintenance user at a time has full access.
Operator: has access to measurements and monitoring functions (error reports and history function) of the R&S ETX-T. Cannot alter or vary instrument settings.
Query User: has access to restricted measurements (main measurement window and MPEG2 tree structure) and all monitoring functions (error reports and history function) of the R&S ETX-T. Cannot alter or vary instrument settings.

Graphical user interface

The graphical user interface (GUI) of the HTML page of the R&S ETX-T has been optimized to include the latest web browser functions (Internet Explorer V4.0 or higher recommended). The GUI can be customized to each site (site name, input RF frequencies, TS names) if at least maintenance user rights are available.

The examples below show possible HTML pages of the R&S ETX-T.

Enhanced features

The Scan mode allows the R&S ETX-T to go through (scan) a user-defined frequency list. This frequency list defines a separate parameter set for each scanned frequency, e.g. duration of monitoring, receiver settings and thresholds of measured parameters.

The History function graphically displays the selected parameters (synchronization, level, MER and BER measurements), as shown in example 3. This function can be used in conjunction with the Scan mode to obtain a global site overview at a glance.
