Mach 6 User’s Manual Revision 2.1 18
Calls a display of measured data sampled at a 10Hz rate. Calling the display side affects:
Range, Trigger Level, Trigger Source, Trigger Polarity, and Trigger Delay
as these parameters are controllable from the Live Mode Display VI. The data may be
logged to a file for later analysis. Note that the statistics displayed are being performed on
the data set. To reset and start a new batch of statistics, press the Clear Plot button. The
display averaging is a moving average. This means that the average will not be complete
until all the samples are taken, but the displays will reflect the current averaged value
until this happens. Suppose that a batch size of 5 is selected, and then Apply Display
Averaging is selected. The samples will be averaged as follows:
Sample Number Number Averaged
1
1 sample summed, divided by 1
2 2 samples summed, divided by 2
3 3 samples summed, divided by 3
4 4 samples summed, divided by 4
5 5 samples summed, divided by 5
The averaging filter is now full. As each new sample is taken, it will replace the oldest
sample and a new average will be computed based on the new data set, that is sample 6
will replace sample 1, the and the new set will be averaged.
