Rohde Schwarz THR9 FM N+1
The Rohde Schwarz THR9 FM N+1 is an FM Audio Transmitter system capable of configuring multiple transmitters in an N+1 setup in a single rack.
About
This protocol can be used to monitor and perform basic configuring on the parent element and generated DVEs.

Installation and configuration
Creation
SNMP Main Connection
This connector uses a Simple Network Management Protocol (SNMP) connection and requires the following input during element creation:
SNMP CONNECTION:
- IP address/host: The polling IP of the device, e.g., 10.11.12.13.
SNMP settings:
- Port number: The port of the connected device, by default 161.
- Get community string: The community string in order to read from the device. The default value is public.
- Set community string: The community string in order to set to the device. The default value is private.
Usage
The Rohde Schwarz FHR9 FM N+1 protocol generates a virtual element (DVE) for each transmitter in the rack/frame, defined by the Rohde Schwarz THR9 FM N+1 Transmitter protocol. Each DVE automatically receives a specific name based on the slot number of the device and the main element's name, e.g., "Rohde Schwarz FHR9 FM N+1.Transmitter A2".
Main Element
Devices
On this page, the Transmitter Control Table provides a summary of all available transmitters in the rack, mentioning among others the Redundancy Mode, the Amplifier Type and the State of the DVE.
Backup Configuration
On this page, you can configure the redundancy settings. Tooltips provide information about each parameter.
In the Program Table, you can add or remove a transmitter from the N+1 configuration with the Program Changeover. Program Operation Mode is used to enable or disable a transmitter.
If a transmitter has been taken over by the backup transmitter, this is shown with the Loaded Transmitter parameter. Enabling or disabling the N+1 configuration is done with the Operation Mode.
Liquid Cooling
This page provides a summary of the cooling of each slot in the rack.
Note that the index is not a concatenation of the transmitter index and the parameter number, but a concatenation of the rack slot number and the parameter number.
Liquid Cooling Pump
This page provides a summary of the liquid pump state information, such as the communication state, summary state and the current flow rate.
Transmitter pages
These pages provide a summary related to the following items:
- Mobile Transmitters
- Tx - Transmitters
- Tx - Exciters
- Tx - Input/Output
Virtual Elements
Tx - Transmitters
This page contains a summary table, and allows you to enable or disable the transmitter with the Transmitter Operation Mode. Some basic power parameters are displayed, such as the Efficiency, the Nominal Power and the actual power of the device.
Tx - Exciter
On this page, the Exciter Frequency and Output Attenuation can be adjusted.
Tx - Input/Output
This page provides a summary of the in-and outputs for the relevant DVE.
Tx - Amplifier
This page provides information related to the values from amplifiers 1 and 2 (for each transmitter).
Tx - Amplifier Status
This page provides information related to the status from amplifiers 1 and 2 (for each transmitter).
Liquid Cooling
This page provides a summary about the liquid cooling state (for each transmitter).
Notes
When creating an alarm template, keep in mind that the value for the State columns is not the same for all rows; each row is a different parameter. The alarm template can be configured to have different alarms for different row values with the Filter option.
For example, if there is a row with parameter Transmitter Summary, then it is logical that the State value Ok is a normal value. But if the row with parameter Locally Controlled has the value Ok, this could be an alarm value.
