Collect and store power readings between certain interval of time from Newport power meter 2936R using Labivew

[hariharan1992]

Hello every one!!

I need to collect and store power meter readings from Newport power meter 2936R using Labivew 11. I installed the necessary instrument drivers. I need to collect 10 readings in one second and next 10 readings in next 10 seconds like that. I need to collect power meter readings for particular time interval and store those values. Can anyone please help me in this regard??

Hi hariharan,

get the readings and store them in an array…

what's your exact problem?

Where are you stuck?

What have you tried so far?

Sounds like a simpel FOR loop will do the job for you.  Use an array to determine you waits.

Thank you very much for your reply sir.

I tried using "get power" option which is available in instrument driver itself. but it is measuring very slowly. How can i get 10 readings in a second.

for example in one second(t1) it should collect 10 readings, and next one second (t2) it should not collect any reading. and next second (t3) it should collect 10 readings like this. 

 that means at t = (1,3,5,7,9,.....)seconds, should collect 10 readings in each and store.     then  at t = (0, 2, 4, 6 , 8,..........)seconds it should not collect readings. 

And also I need average of that 10 readings in every second ( t=1,3,5,7....) sec. 

How to construct a VI to measure power between required time intervals.

I assume you mean the library found here: http://www.newport.com/Optical-Power-and-Energy-Meters-1936-C-R-and-2936/744081/1033/info.aspx#tab_L...

There is a PerfromDAQ.vi in there.  Perhaps that will do what you want.  Otherwise, I'd say you need to talk to Newport about their driver.
