vrf Array data Processing

Question asked by VRFuser on Dec 15, 2003

I've done something like this before.  I think it can be done, but it takes
a little book keeping along the way.  The first thing that I did was
establish what the repeat pattern would look like.  For your 1st set of
data, it looks like the data block starts every 3 data points, but on
occasion it does it at 4 data points.  What I did was set up an array
index, read the 1st 3 points, ignore the 1st point of those 3 (reading
point #2), test for 1 or 0, then go to the next data block .

example:
Array data is : 111000111000 this should be processed as 1-0-1-0
              start here--------^
read this point-------------^-----^----^----^---

may get         1111000111000 which is also 1-0-1-0
              start here--------^
read this point-------------^-----^----^----^---

Also

may get         1110000111000 which is also 1-0-1-0
              start here--------^
read this point-------------^-----^----^----^---

I hope this comes through clear with my crude editing here.  I have used
this on the 54645D MSO, 54622D, and an older logic analyzer

Good luck

Hi vrf,
I am using an Agilent 1672G Logic Analyzer to observe a digital signal (1
pin)
After transferring the data from logic analyzer to my pc, i want to process
this data to obtain the correct bit stream.

Here comes my question;
After eliminating the unwanted data, i can obtain the sampled data which is
an array of 1 and 0s)

For example :
Array data is : 111000111000 this should be processed as 1-0-1-0
but due to my sampling period i may get 1111000111000 which is also 1-0-1-0
(i.e block length can be 3 or 4 but 3 is more frequent)

Iam including some other examples to indicate my problem clearly:
111111000000  should be processed as 1-1-0-0
000000000000111 should be processe as 0-0-0-0-1

Good luck to all.
