Advanced Configuration settings of a (D.A.R.E!!) Field probe

Post by sast »

When I press the 'Advanced' button in the Field probe settings window, a new window with multiple tabs is showed.
Please provide a brief description of how these settings should be interpreted and re configured if needed.

Advanced Configuration settings of a (D.A.R.E!!) Field probe

Post by sast »

Normally, there is no need to change these settings and the default settings are used.
  • Wait time: the minimum time that should be waited between each measurement
  • Max. Difference: the maximum difference that is allowed between the <Measure> measurement value(s); the highest and the lowest values are compared.
  • Measure: the minimum amount of measurements that has to be performed to determine if the <Max. Difference> condition is met
  • Max. Measure: the maximum amount of measurements that could be performed, before there is a final measurement value available (which could meet these conditions, or not)
According the settings in the screenshot above, RadiMation will perform:
A minimum of three measurements, with a maximum of ten measurements, and a wait time between each measurements with a minimum of 75ms. The following cases are possible:

First case (after the first - minimum amount of - measurements are performed):
The first (<Measure>) 3 measurements are performed and the results are WITHIN the difference of (<Max. Difference>) 0.1dB, then the last measurement value (of those three measurements) is used.

Second case (more measurements are needed):
The first (<Measure>) 3 measurements are performed and the results are NOT WITHIN the difference of (<Max. Difference>) 0.1dB, then one new measurement is performed and RadiMation will use again the last three measurements (thus, the first measurement will be neglected) to determine if the results are now within the difference of (<Max. Difference>) 0.1dB. This process will repeat until;

Third case (last measurement is done):
The above settings and conditions are not met after the last measurement is done (and the <Max. Measure> value is reached), then measurement value of the last measurement performed is used as the correct measurement value.

For more clarity we can use the following graph to explain the behavior of RadiMation according these settings:

When we use the same settings as in the previous posts, except for the wait time (we now use 1ms), then we are able to define the following statements:
  • The first measurements will consist of T1, T2 and T3, because the <Measure> (minimum) value is set to 3
  • The time difference between these measurements will be at least 1ms
  • The difference is determined between T3 (highest) and T1 (lowest)
  • This difference value is NOT WITHIN the defined max. difference of 0.1dB, therefore;
  • Measurement T4 is performed
  • The measurements now consist of T2, T3 and T4 (T1 is now neglected)
  • Again, the difference is determined, but now between T4 (highest) and T2 (lowest)
  • Again, this difference value is NOT WITHIN the defined max. difference of 0.1dB, therefore;
  • Measurement T5 is performed
  • The measurements now consist of T3, T4 and T5 (T1 and T2 are now neglected)
  • Again, the difference is determined, but now between T5 (highest) and T3 (lowest)
  • Again, this difference value is NOT WITHIN the defined max. difference of 0.1dB, therefore;
  • Measurement T6 is performed
  • The measurements now consist of T4, T5 and T6 (T1, T2 and T3 are now neglected)
  • Again, the difference is determined, but now between T6 (highest) and T4 (lowest)
  • Again, this difference value is NOT WITHIN the defined max. difference of 0.1dB, therefore;
  • Measurement T7 is performed
  • The measurements now consist of T5, T6 and T7 (T1, T2, T3 and T4 are now neglected)
  • Again, the difference is determined, but now between T7 (highest) and T5 (lowest)
  • Again, this difference value is NOT WITHIN the defined max. difference of 0.1dB, therefore;
  • Measurement T8 is performed
  • The measurements now consist of T6, T7 and T8 (T1, T2, T3, T4 and T5 are now neglected)
  • Again, the difference is determined, but now between T8 (highest) and T6 (lowest)
  • Again, this difference value is NOT WITHIN the defined max. difference of 0.1dB, therefore;
  • Measurement T9 is performed
  • The measurements now consist of T7, T8 and T9 (T1, T2, T3, T4, T5 and T6 are now neglected)
  • Again, the difference is determined, but now between T9 (highest) and T7 (lowest)
  • Again, this difference value is NOT WITHIN the defined max. difference of 0.1dB, therefore;
  • Measurement T10 is performed
  • The measurements now consist of T8, T9 and T10 (T1, T2, T3, T4, T5, T6 and T7 are now neglected)
  • Again, the difference is determined, but now between T10 (highest) and T8 (lowest)
  • Still, this difference value is NOT WITHIN the defined max. difference of 0.1dB, however;
  • The <Max. Measure> value is reached and 10 measurements are performed, so no new measurements are taken, therefore;
  • The measurement value of the last measurement performed is used as the correct measurement value, thus T10

The latest configuration window has been further improved and now looks like:

  • Pre Wait time: the minimum time that should be waited before the measurements starts
  • Measure: the minimum amount of measurements that has to be performed to determine if the <Max. Difference> condition is met
  • Wait time: the minimum time that should be waited between each measurement
  • Max. Difference: the maximum difference that is allowed between the <Measure> measurement value(s); the highest and the lowest values are compared.
  • Max. Measure: the maximum amount of measurements that could be performed, before there is a final measurement value available (which could meet these conditions, or not)
If Measure is set to a value of 1 the Wait time, Max. Difference and Max. Measure settings will be disabled, because only one measurement will be performed.

As you can see it now also shows "Monitoring" measurements settings.
The behavior of all parameters are equal to the "Levelling" measurement settings.
Only the momentum is different when which set of settings is being used:
- Is during the test the field sensor used to regulate: levelling settings are used.
- Is during the test the e.g. the power meter is used to regulate, and field is also measured: monitoring settings are used.
