Data acquisition and frequency generation togather with PCI-6251 and LV8.2

[Manohar]

Hi friends,

I am a new user of Labview. I am using LB8.2 with PCI-6251 .

I have to generate frequency and then measure the data and then for next frequency and so on.

i know that for this i have to use looping and that is not a problem. The real problem for measurement is to identify whether the frequency is been generated. if yes then measurements starts otherwise it should wait until it started. then after finishing the measurements send a signal to generator for changing the frequency and amplitude.

Now these two things {generation and measurement} togather are not working correctly for me. so i make 2 diff file, one for generation and other for measurements <by modifying the examples>. I can run both file togather and it works. But it need lots off effort and time. I have to measure from 10Hz to 1000Hz in 2Hz frequency step and i cannt leave in between :mansad:.

can anyone help me how to syncronize these two togather :mansurprised:.

Trying to attatch. both the files here ..

main_v1.1.vi --> for Measuring

Oscilloscope.vi --> for waveform generation

what you need to do is achieve multi function synchronization,

In labVIEW

Find Examples>> Hardware input and output>> DAQmx>>Synchronization>>Multifunction>> find Multi-Function-Synch AI-AO.vi

this would be the best example to start with

can you suggest some alternative for the current example.

I have only  GBIP, Instrument Drives, Serial, Sound, VISA

 in path Find Examples>>Hardware input and output>>

thnkyou for reply

Hay thnx dude..

I found the example and now it works 🙂

once again thanks a lot
