measurement analysis using TDS3000

[nizam2]

Hello

HI. i am using TDS3000 downloaded from NI website

Actually graph that is produced from labview measurement as i attached in the attachment. ie the labeled came out as

Vpeak= ___V

90% OF the graph in term of seconds

10% of the graph in term of seconds

As i am doing impulse testing i need those parameters for analysis 

Here also i attached my modified programming

I don't understand what your problem is.  Are you just trying to make the measurements and don't know how to?

hi thanks for reply.

I have an xy-graph and I would like to insert programmatically some text label connected to certain x-y coordinates of the plot itself and display it at the front panel

Well, you have the array of data.  So just use the Array Max & Min to get the peak voltage.  From there, get your 10% and 90% voltage levels and use Threshold 1D Array to find the index of those points.  You may need to use Interpolate 1D Array with the resulting indecies and the time array in order to get your time of those points.

From the peak value, is there any method for it to plot itself 10% and 90% voltage levels crossrulz?

Not itself.  But you can easily make the lines and add them to the graph plot.

Hello I have 1 more problem related to this topic, which is i planning to do an array for my programming, but the wire cant connect each other. Here i attached the picture of my problem. Hope someone can help me
