R&S®Tx9 Device View Description System Overview ● Fault Limit (in dB) Fault threshold: can be set between 0 dB and ‒20 dB. ● RF Fail Timeout (in s). Delay time: can be set between 0 s and 10 s. This is the time between undershooting of the "Fail Limit" fault threshold and indication of the fault in the transmitter status display. 4.1.2 Reflected Power ● Path:Device View Home > TX An The "Reflected Power" field indicates the reflected power of the transmitter system in W.
R&S®Tx9 Device View Description System Overview Program The currently active program 1 can be switched off using the "Program 1 – ON/OFF" button. 4.1.4 N+1 Redundancy The task of the N+1 automatic function is to provide a B standby transmitter for up to eight A transmitters. This B transmitter takes over the program of an A transmitter if an A transmitter signals a fault. The output of the B transmitter is normally connected to a dummy antenna.
R&S®Tx9 Device View Description System Overview stored for the A transmitters are synchronized with the B transmitter automatically even if the B transmitter was switched off when the settings were stored. If the program‑specific settings are changed at A transmitters without these settings being stored as presets, the changes will not be available on the B transmitter in the event of a switchover. Presets can only be stored on the A transmitters.
R&S®Tx9 Device View Description Transmitter Name Description Value range Access right Switch Mode (Auto Switch) Used to define the switching behavior of the N+1 automatic function. Single switch: Switchover of an A transmitter to the B transmitter can occur once only. Multiple switch: Following a switchover operation, the system can switch back to the A transmitter automatically when the A transmitter no longer signals a fault but the B transmitter indicates a fault.
R&S®Tx9 Device View Description Transmitter 4.2.1 Automatic Switchover 4.2.1.1 Automatic Input Signal The R&S®TCE900 in the R&S®TCE900 exciter configuration has an automatic switchover function which, in the event of a signal failure at one logical input, switches over to the other logical input (provided that a valid input signal is available at the other logical input). Before a failure occurs, the preselected input is active.
R&S®Tx9 Device View Description Transmitter Selecting this operating mode minimizes the number of switchover operations and, in certain cases, the number of breaks in transmission. Direction of switchover (Switch to) The "to reserve and back" switch position enables switchover in both directions, i.e. to and from the standby input, depending on which of the two logical inputs is currently faulty. The "reserve" switch position ensures that switchover takes place once only.

If seamless switching is possible, switchover always takes place immediately without interruption regardless of the set guard time. If "to Reserve Only" was selected as the "Direction", the set guard time has no effect.
R&S®Tx9 Device View Description Transmitter "Multiple Switch" Mode This mode is identical to "Single Switch", except that following a double switchover operation the "preselected" exciter becomes the active exciter again. The "Automatic Changed" message is still displayed in this case.

A description of the device must be loaded in the central unit ("manager"; management information base (MIB)), from which the transmitters are monitored.
R&S®Tx9 Task View Description System Control Fig. 5-1: SNMP menu The XX9 transmitter family supports the versions SNMPv1 and SNMPv2c. Alarms can be sent as v1Traps, v2Traps or v2Informs. Several destinations for error messages (trapsinks) and several communities can be set with read only authorization and read/ write authorization. SNMP is a protocol for remote control and is offered only at the remote Ethernet interface (X2 – 1000 BaseT).
R&S®Tx9 Task View Description System Control Fig. 5-2: SNMP manager settings Being able to monitor and control a transmitter with SNMP requires the device's MIB on the manager end and a program that can interpret the MIB.
