Lock-In Amplifier and offline data processing

[alaistor]

Hi everyone,

I've been successfully using the Lock-In Amplifier to do live data processing. The processed Lock-In outputs and the frequency values are then saved. Recently it has turned out that the real acquisition capabilities needed mean that online processing is not possibe. (As 4 channels are being simultaneously sampled each at 4Mhz and acquiring for several seconds.) I have built the Lock-In Amplifier into an offline processing VI where I strip out the arrays for Channel 0 (Signal) and Channel 1 (Reference) and send chunks of data to the Lock-In. I wanted to check that the Lock-In doesn't have any problems working offline? Are there any other things I need to know for offline processing?

Many thanks

Hi,

I've not personally had the change to use Lock In Amplifiers with our hardware yet, but from searching through the LabVIEW developer zone I came across this example VI, I hope it's some help to you: http://zone.ni.com/devzone/cda/epd/p/id/4532

All the best,
