Hi All,
I have just pulled most of my hair out & setup an old PC Data Acquisition card in an old computer, it has an oscilloscope function etc but with no instructions--secondhand.
I have hooked up a circuit to read the frequency of the pulses to test things out, after much playing around i have what seems to be a good reading on the Monitor?
Is this ok for a reading of the frequency of a circuit?
Now i need to learn how to read this, can somebody please help me out.
I have attached a picture i have taken of the reading, it is a little out of focus.
Far Left verticle column of numbers is Voltage.
The time readings are a bit hard to read on the bottom but from left to right read:
0s 163.80us 327.60us 491.40us 655.20us 819.00us 982.80us 1.15ms 1.31ms 1.47ms 1.64ms.
I am not sure how to work out the frequency of this circuit or how many us or ms in a second etc--AARRGGGHHH!!
Not sure even if i have the settings right to do this?
The pulses vary so what do you call this type of Signal?
Also on the reading on the Horizontal lines --just below centre--some are a little fuzzy, is this just some sort of electrical interference?
Thank You
