qFrequency measurement

The frequency measurement function helps user to measure the frequency of the signal from counter-associated clock input on PCLD- 8712.

Frequency measurement needs two counters to implement. Use the first counter to produce a one-shot pulse with defined pulse period to be the second counter’s gate. Connect the signal source, whose frequency is to be measured, to the clock input of the second counter. Since the one-shot pulse generated from the first counter is always a negative pulse, we have to set the gate input type of the second counter as logic low for proper frequency measurement.

The second counter starts to count once the gate is set to low and stops when the gate is high again after a period of time. Assume the measured frequency signal is the regular pulse, then we can calculate its frequency by the period of one-shot and the value of second counter.

Please follow the procedure below when using software:

1.Select the first counter to do one shot and specify its pulse period.

2.Connect the signal output CNT1_OUT of the first counter to the second counter’s gate input CNT2_GATE.

3.Select the clock source of the first counter. (Could be internal or external)

4.Set the gate type of the first counter to positive (logic-high), and the second counter to negative (logic-low).

5.Reset the second counter to 65,535.

6.Pull high the gate input of the first counter and start to do frequency measurement.

7.Read the value of the second counter.

8.Evaluate the frequency of the measured pulse.

For example, if frequency measurement is done with the second counter value set at 65,535 and the period of one-shot from the first counter set at 0.1 sec, then the value of the second counter we get back is 43930. Thus, the frequency of measured pulse could be calculated as (65535-43930)/0.1sec. = 216050 Hz.
