What have you tried so far ?
What is "bounce time" -define it carefully.
...and we're not here to do your job for you.


Defining bounce Time,
It is the time duration of intermittent opening and closing of the Reed contact during contact closure (or) it is the time duration of intermittent closing and opening of the reed contact when the reed contact opens. But not sure whether both time intervals are equal!
Having this in mind, i tried to analyse how far, the circuit i have, could help me to measure the bounce time, but couldnt arrive at any useful results. So i thought of getting few hints by posting it here, which would help me do with the measurements.

Kai Said:
The schematic is incomplete, in so far that important signals aren't explained. For instance, what is "Sense3+"?

That is the problem I face Kai. I have only that card with those signals coming out of the connector pins (as shown in the circuit). But not having any explanations regarding it for my reference. So I am unable to give you those details.
So with this situation I only intend to know whether I could measure the bounce time of reed switches using that card setup (with or without any additional circuitry).
If i could measure, then need some suggestions on how it could be done since I couldn’t find one.
Any hints would be helpful for me to find a solution.

Kai Said:
Also, with what is the reed relay switch contact of DUT connected, to measure the switch resistance?


I thought of using the 10mA_out1 to pass through the contact for CR measurement purpose. Sense1+ and Sense1- to sense the drop across the contact.


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

                     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

                                          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

                        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      
                           A joke and fooling someone is NOT the sa            01/01/70 00:00
