Synchroniz​ing RF message with preamble

Question

Hi
With CVI & NET, I am able to synchronize the incoming string of messages with preamble, using a function ModtMapBitsToFSKSymbols. But only with the first message,  i need to be able to synchronise the subsequent message with preamble. I have been looking for examples in CVi to no avail. I would appreciate the help.
Best Regards
Shane

You need I-V curves and you aren't afraid to spend the boss's money to obtain good data.  At least, as long as the data is reliable.   I do this type of thing for fun (and a paycheck) every day BUT, I'm insomniatic right now so I'll try this pro-bono.
Voltage and current ranges and required accuracies?
Test cycle time for the Device Under Test?
Have you looked at a SMU? If so, why did you chose your set-up and how will you address phase shifts between I and V waveforms due to lack of common timing between the 6229 and the load?  There are great solutions for most common test applications available off-the-shelf and geeks like me to develop the uncommon ones or find one that is available.  
Essentially, my general feeling for your proposed materials and methods is that, because of the timing, you may not get any bang for your buck.  You chose great instruments but, the time issues cannot really make them play together without a penalty in either accuracy or time per DUT per throughput years under warranty (T/D/TPY) and that's going to cost in operator hours.
Thanks for responding, Jeff!
Voltage range from 0 - 120VDC
Current range from 0 -  6ADC
Test cycle time is not well defined, but it does not have to be very fast.  I'd like to capture all I and V points in one sweep, but the slew rate can be relatively slow.
I don't know what an SMU is.  I will research.
Any further suggestions would be greatly appreciated.
