I have a 2 channel Oscilloscope that is 25Mhz in speed and want to check XBee FAULT with it ? Any approaches?
What kind of XBee? Serial (UART) inteface? What do you wanna achieve?
Two channels should be enough to capture RX and TX but only if you think that the signal condition is bad. To analyse the bit stream you should have a Logic Analyser, typical Oscilloscopes don't have enough storage capabilities to hold the protocol bytes. So what kind of fault do you have?
Actually the XBee was working very fine , there were three xbee's initally i configured all 3 then left one for about 20 to30 days and 2 were utilised and they are still working the same , so i picked this one up after a long time and put it into the FIO and no communication with the other 2 so i was trying accessing it using my CP2101 chip driver and also the FTDi 232 driver on the Deumilanove , but its not being read at all on the X-CTU however implying the same method and procedure + connections works for my other 2 xbee's
Have you already checked if there are signals transferred?
There is on way leaving the Dmm, any other way I can make that check?
What's a Dmm? What other ways? Just connect your scope to RX/TX and see what you get. At least the TX line should have output else something other than your Bee is faulty.
Ok so you mean ,if the tx has something while the xbee is powdered them it means its good
