 		 #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,
Suresh.

            Of course its a good idea ;-)            01/01/70 00:00      
               also..            01/01/70 00:00      
                  Rather redrawing, i prefer ...            01/01/70 00:00      
   Schematic is incomplete            01/01/70 00:00      
      Simple way            01/01/70 00:00      
   I would do it like that            01/01/70 00:00      
      detecting end of bounce?            01/01/70 00:00      
         Much simpler            01/01/70 00:00      
            this is all getting complicated            01/01/70 00:00      
               there may be definition problem here            01/01/70 00:00

                     You're right, of course            01/01/70 00:00      
                        They tell it here            01/01/70 00:00      
                           Yes, it's pretty complete.            01/01/70 00:00      
                              Form A            01/01/70 00:00      
                     More sophisticated? Maybe not.            01/01/70 00:00      
                        OK brass tacks            01/01/70 00:00      
                           that's the basic idea            01/01/70 00:00

                                 that wasn't the point, Suresh            01/01/70 00:00

                                       Really?            01/01/70 00:00      
                                          I doubted when i typed            01/01/70 00:00      
                                             and the manual is right! sorry.            01/01/70 00:00      
                                                Really?            01/01/70 00:00      
                                                   correction            01/01/70 00:00      
                                                      There could be. But I made the mistake            01/01/70 00:00      
            Quantum flux compensator?            01/01/70 00:00      
               is it still April 1            01/01/70 00:00      
                  You are right but,            01/01/70 00:00      
               he means a flux capacitor ...            01/01/70 00:00      
                  And I thought...            01/01/70 00:00      
                  Compensator            01/01/70 00:00

                  reply : april 1!            01/01/70 00:00      
                     no, it was a natural response            01/01/70 00:00      
                        Ok Erik.            01/01/70 00:00      
                           The "Flux Capacitor" is from a movie            01/01/70 00:00      
                              Yes. to some extent!            01/01/70 00:00      
                     Never wanted to fool you!            01/01/70 00:00      
                        Obviously            01/01/70 00:00
