How can I detect MIN and MAX values of inputs to NI-Scope (NI PXIe-1073) channels?

[Henok]

Hello Everyone,

I have the need to detect the min and max values to input channel signals to NI PXI-5105 card in NI PXIe-1073 chasis. My exact requirement is to be able to detect the maxima and minima of the input signals based on a cycle where the first channel input is TDC (Top Dead Center) and the second channel input is CAD (Crank Angle Degree). So every cycle (between two TDC pulses) I need to detect where the maximum or the minimum values of the other channels are detected and presented in their corresponding CAD values.

I appreciate tips to which already existing VIs I can use ( hoping that there are already) and a guide to the right direction in tackling this problem.

Many Thanks!

Hello again,

I would like to refine my question above. My current difficulty is I have a cluster of two arrays; lets say X and Y. The X values are data values of channel input and the Y values gives the corresponding CAD values of the X array elements. So my ultimate question is to detect the most positive or negative of the X values and output that value together with its corresponding Y value in the cluster.

I really appreciate the help!

Hello Henok,

Take a look at the example attached below. Extracts the Min and Max from the X array and also corresponding Y value.

Best regards,
