Description: Monitors DVB signal characteristics including signal level, SNR, and BER for digital video broadcast quality.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is DVB-MGSIGNALCHARACTERISTICS-MIB?
This vendor-neutral DVB Measurement Group MIB captures RF and transport-stream signal characteristics to assist in interpreting broadcast quality tests defined by ETSI TR 101 290. It exposes signal-level, signal-to-noise ratio (SNR), bit-error-rate (BER), and transport-stream structural information. Its focus is on monitoring the hardware/RF performance of broadcast reception or transmission equipment: degraded SNR or rising BER directly indicates a weakening RF signal or transmission fault that could cause viewer-visible picture problems. It is designed to complement DVB-MGTR101290-MIB and the ETSI TR 101 290 test specification. It is typically deployed at DVB broadcast headends and on dedicated signal-measurement probes in digital TV network operations, where engineers consult a DVB-MGSIGNALCHARACTERISTICS-MIB reference to map raw OIDs back to the ETSI TR 101 290 test parameters they represent.
IPNetwork Monitor allows you to monitor SNMP objects defined in DVB-MGSIGNALCHARACTERISTICS-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer
- DVB broadcast measurement probe/headend equipment
Monitoring Examples
No sample objects were supplied for this module, so specific table names cannot be cited with confidence. Conceptually, an engineer would poll signal-level, SNR, and BER objects on a measurement probe to detect a degrading RF signal path before it causes visible transport-stream errors. A steadily rising BER alongside falling SNR would typically indicate a failing amplifier, cable, or antenna alignment issue upstream.
What Can Be Monitored
- RF signal level
- signal-to-noise ratio (SNR)
- bit error rate (BER)
- transport stream structure parameters

The agent automatically changes the value back to 'enabled' when the time specified by trapControlPeriod expires. A management application may set the value to 'enabled' at any time, but must never set the value to 'enabledThrottled'. |

| INP structureTrapControlInputNumber | 1.3.6.1.4.1.2696.3.3.1.1.1.1.1.1 | InputNumber | not-accessible | Transport Stream input to which the trap control objects apply. |
| OID structureTrapControlOID | 1.3.6.1.4.1.2696.3.3.1.1.1.1.1.2 | OBJECT IDENTIFIER | accessible-for-notify | This object holds the OID of the object within the mgTSStructure branch of the MIB whose change triggered the trap. It is present for the formal purpose of defining the variable bindings returned with the tsStructureChangeTrap. It is not accessible for normal reading. |
| U32 structureTrapControlPeriod | 1.3.6.1.4.1.2696.3.3.1.1.1.1.1.5 | Unsigned32 | read-write | The agent will ensure that the interval between sending traps is no shorter than this time period (unless overridden by the manager). |
| RAT structureTrapControlRateStatus | 1.3.6.1.4.1.2696.3.3.1.1.1.1.1.4 | RateStatus | read-write | This object is used for rate control of traps, preventing overload of the management network by transmission of an excessive number of traps. The value 'disabled' means that traps are never sent. The value 'enabled' means that a trap will be sent when triggered. When a trap is sent, the agent changes the value of this object to 'enabledThrottled'. In this state the agent will not send any more traps. The agent automatically changes the value back to 'enabled' when the time specified by trapControlPeriod expires. A management application may set the value to 'enabled' at any time, but must never set the value to 'enabledThrottled'. |
| structureTrapControlTable | 1.3.6.1.4.1.2696.3.3.1.1.1.1 | not-accessible | Per-input table of values which control the generation of tsStructureChangeTrap traps. | |
| INP structureTrapInput | 1.3.6.1.4.1.2696.3.3.1.1.1.2 | InputNumber | accessible-for-notify | The Transport Stream input whose change triggered the current trap. This information can also be obtained by analysing the structureTrapControlOID, but structureTrapInput provides the information directly. This object is present for the formal purpose of defining the variable bindings returned with the tsStructureChangeTrap. It is not accessible for normal reading. |
| structureTrapPrefix | 1.3.6.1.4.1.2696.3.3.1.1.1.0 | |||
| NTF tsStructureChangeTrap | 1.3.6.1.4.1.2696.3.3.1.1.1.0.1 | Trap which is sent when any value within the mgTSStructure branch of this MIB changes. Transmission of the trap is subject to rate control through the structureTrapControlRateStatus object. |
