mismatched input channels

[wojtekd09]

Hi,

I have problem with Formula module. Mismatched input chanels: the time information or block length of the input channels do not match ...

My sampling rate 100kHz and Block size: 16384. I add my Worksheet.

Sorry for the delay in responding. Happy New Year.

The two channels going into the forumla have different block size and sample rates. The Formula expects all data coming in to have the same sample rate, block size, and time stamp. 

The Statistics module outputs one value for a block of data. 

Your sample rate is 100 kHz, with a block size of 16384. The FFT module reduces the block size to 8192.

The Statistics module on Channel 0 is outputting one sample blocks with a sample rate of 6.1035.

The second channel going into the Statistics module is coming from the Block Average module. It is reducing the total number of blocks, keeping the sample rate in the block the same (100 kHz) and the block size the same, but the total number of blocks is reduced by 4. It then goes into the Statistics module, where it is reduced again, this time to a block size of 1 and a sample rate of 6.1035. BUT... there are fewer blocks, with gaps - the data channel is now tagged as  "triggered" which means that there are gaps in the data, it's not perfectly continuous.

This Chart Recorder image shows you the problem.

The real question.... what are you trying to do?
