here's what I got.
I found it easier to configure the 89600 software, save this configuration and recall it. If you look in this config file it is huge, every possibile parameter is saved and pushed back into the app when recalled. This insures that every test has the same base configuration any time it is run. There are way to many parameters to bother creating graphical interface controlers for.
As you cann see in the junk yard programs, what I do is setup the MXA/89600 to record a chunck of data given some timing signal as the start of time (or your known test pattern). This avoids needing to create a searcher in labview, to find the start of the test patter, and also adjust the record overlap. Thats somehting that gets nasty, you might want to talk with Agilent feild engineer about what it is and how to figure out what to set it to. They explained it to me but that only let me realize i didn't want to mess with it if I could aviod it. I put a note about this field in the main vi tree:
About using overlap in the search function of the 89600 [recorded] buffer:
Say your packet is 720 ms (data is conitguous though not bursty), and the maxium
capture of the analyzer is 853.33333ms
And you tirggered the record right at the begining of your buffer, then to be sure you
don't search through previous portions of your 720ms packet you set your search to:
(853.33333-720)/853.33333 = 15.625% overlap, the 89600 will search right form the
end of your first packet and find the next one.
If you don't have time 0 at the begining of the record, each time you step to the next chunk of buffer you might not get enough new data (based on the overlap) to dump the specified packet length. The 89600 does wierd things when the overlap didn't let in enough data from the recording (bogus demoded bits) even though it is a recording and there is data there (the sliding window is really a separate buffer duped from the recorded data based on overlap and search length). This is all so you can capture a contigous data signal.
Enough of that feel free to post questions about this when it comes up.
