Link your test data to specifications so you can compare measurement results to specification limits.

The Spec ID is the primary key you use to connect a specification to a measurement.

You must store your parametric data as test results under the product that contains the specifications. Each measurement under a test step must include a field called specId for each parameter that you link to a specification.

In the following example, the Voltage measurement parameter is linked to the specification with Spec Id = OutputVoltage1:
{
  "name": "Voltage Step",
  "data": {
    "parameters": [
      {
        "name": "Voltage",
        "measurement": 15.234049,
        "units": "mV",
        "specId": "OutputVoltage1"
      }
    ]
  }
}

If you collected the test data using the Bench Data Connector (BDC) Logging Libraries, use the BDC file ingestion service to ingest the data. The BDC file ingestion service automatically captures the Spec ID on each measurement.
