#113653 - Measuring Bounce of a Reed Switch
Dear all,
I am having an EISA card that is designed to measure various factors like pullin(PI) dropout(DO),VPI, VDO, CR, VCR, Bounce time, Rise time, fall time of a Reed Switch under test. Presently the driver software is programmed to measure only few of the above.
So, now i need to include the Bounce time measurement in the software but, couldnt get a way to do that.

So,i would like to get some assistance with this issue.

Coming to the Hardware part that facilitates the bounce measurement is.,

the card has a programmable gain amplifier(PGA202) and a Programmable 8254 to measure the bounce time.

The link below shows the detailed circuit.

Kindly let me know for a suitable method to measure bounce time using this circuit (or) about a procedure, in general, used to measure the bounce time of the reed switch. So that i could relate it with mine to find some solution.

Thanking you,
