please help me

hello all

now I have two graph one is Drain current corresponding to time, the other is drain current corresponding to gate voltage, you can see these from the attached files. Now I need to get the value of gate voltage of every point of first graph. how can I get a graph of gate voltage value corresponding to the time?

thank you for any help!

Hi Jing

Try this : see attachment.

This VI scans each value of drain (vs time), and looks up this value in your lookup tabel (gate to drain), and gives the corresponding gate value.

If you are using waveforms, you need to extract the arrays of date out of them, to use this method.

Afterwards you can rebuild your waveform.

Also, please note that it looks like you actually posted a bitmap file and just changed the extension to jpg. Changing the extension does not change the format of the file.

Bitmaps are frowned upon because they are so large. PNG is the preferred format for screenshots or figures as they create much smaller files. Your 2.2 MB BPM saved as a PNG is only 66 kB (33 times smaller).

Dear ThomasV

Thank you for your reply, but please tell me the exact position of that VI, I can not find it

Thanks

Hi Jing,

see the attached picture. The vi is called "Threshold 1D Array".
