export data signalexpress

[babb27]

Hello,

I am using SignalExpress to log some data. I have recorded the data I want and analyzed it in the playback function. The problem occurs when I bring the data into the "Data View" graph and it cuts my data down to 100ms. But the length of the recording is 51 seconds. I tried saving it to a ascii file but it also only shows the first 100ms.

my sample rate was 1000.

and my number of samples was 100.

i ran the recording taking continuous samples.

I want to be able to save the whole 51 second file into Excel.

please help.

It looks like you need to either sample slower or take less samples:

For acquisition steps in Signal Express, not only do you configure the sample rate, you also input the number of samples to read. For Finite Acquisitions, this input is the total number of samples to be read. However, for continuous acquisitions, this input determines the size of the sample block that will be moved or "read" from temporary memory into the application's memory. It is these chunks of samples that are being displayed on the Dataview, only to be replaced the next time the read function is called and grabs a new chunk of samples. This is expected behavior.

If you would like to display all of the samples acquired since the acquisition began, you will need to use the record option.
