What is considered as "high" or "low" frequency at DAQmx settings

[Aleksi-]

Hello again!

I'm about to make a frequency measurement task using DAQ Assistant. Thus I have to select correct "Measuring Method" for the expected freaquency range. However I have no idea what is considered to be "high freaquency" and what is "low freaquency". I'm expecting to get about 0-300kHz.

Thank you in advance.

Edit. I Corrected the reaquency range in this case to be 0-300kHz

Hello there;

The standard says the following:

However to chose the appropiate constant, you need to check the clock rate on the board you are using to take your measurement. If you use low frequency then you will be using a constant timebase vs using two counters you can add whichever external timebase you want.

Hope this helps.

Greetings
