Efficient way to parse output of VISA Read into array

[i.demarco]

Hello everyone.

I'm using LabVIEW 2015 and I came across an issue. I have several multi-channel instruments, controlled via VISA, which have the capability to perform measurements on all channels simultaneously.

Now, due to the nature of VISA, of course, the output of a query is a string. Suppose for the sake of the argument that it's formatted like

Instrument-Dependent String - CH1 -> 11000101, CH2 -> 235234, CH3 -> 484823, CH4 -> 7394231

Is there a neat way to collect the four (in this case) measurement values without having to construct a bulky pattern-matching structure (Using for example the Match Regular Expression VI)?

Hi i.,

there is SpreadsheetStringToArray:

There are a lot of different options, depending on the structure of the string.

In this case, I would put up a loop to 'Match Pattern' the > character, take the 'after substring' output and 'Scan from string' it as decimal.

Do the same with 'remaining string' output until the 'Scan from string' fails.

Just an example.

Well, GerdW's solution is much quicker to implement!

I would just use a loop with a couple of Match Patterns inside.  You can use that to parse out each value separately and autoindex the output value.
