Better Wait VI

This little Labview Code add a better way to wait since you can wait on previous VI linked trough the error.

 

If you have any questions, just leave a comment and I will post them here.

 

 

 

Crystal accuracy: PPM parameter

Manufacturers usually provides the accuracy or stability of the crystals as a PPM value which basically means how many pulses per million the crystal might drift from the central frequency.

To convert this value into how much hertz this crystal can drift, we can use the following formula

                      F x ppm
Delta F=   ---------------------
                        1E6

i.e. if you have a 16 Mhz with a 10 ppm

                     16 Mhz x 10
Delta F=  ----------------------
                          1E6

Delta F= 160 Hz

You can use a high precision frequency counter to measure the frequency of the crystal.

OnTest blogging?

I've always wanted to start a blog, so this is my opportunity to do
so, even though English is not my mother tong, the intention of this
blog is to reach more and more people, and of course improve my
writing skills in english as well.

I've been working for several years as a Test Engineer on the
Electronic and Semiconductor industry, and before taking seriously
this role, I was in the thought that "testing" was just a part of
developing or designing. But certainly is NOT, and assuming that many
Engineers think as I did before, the main intention of this blog is to
ilustrate why, in many ways "testing" should be taken very seriously.

Also now and then, I will post technical articles that I'll find
intersting or that might help other Test Engineers

See you soon. :)
