I want to use the PXI6602 to measure the  frequency of  a dynamic signal in the  range of 60-300Hz. In my time loop ,I get data  every 10ms. For the 60-100Hz signal,I can get the current frequency in twice.One time use the previous frequency,the other time use current frequency.  But for 100-300Hz signal,every time get at least one data, such as 100Hz only one data and 300 Hz  three data.I found that the   signal within the range of 60-100Hz if the timeout is set to 0.01 seconds, then there will be an error and can not  get any data.Is there any  way that  I can directly read and set the buffer on the board?And  how can I realize  the   program?
