KSPROPERTY_BDA_SAMPLE_TIME
Clients use KSPROPERTY_BDA_SAMPLE_TIME to determine the sample time over which signal level and quality are averaged.
Usage Summary Table
| Get | Set | Target | Property descriptor type | Property value type |
|---|---|---|---|---|
| Yes | Yes | Pin or Filter | KSP_NODE | LONG |
Remarks
The NodeId member of KSP_NODE specifies the identifier of the control node or is set to −1 to specify a pin.
The returned value specifies the sample time in milliseconds.
Each time a client requests a signal statistics property, the node should report the average value for the last n milliseconds where n is the value indicated by KSPROPERTY_BDA_SAMPLE_TIME. If no time value is set or if the driver does not support KSPROPERTY_BDA_SAMPLE_TIME, the driver should default to a sample time of 100 milliseconds.
The driver can report time values for the most recently completed sample period.
