  1. I need to capture a pulse (High to low), which stays for appx 600us, then goes back high. I need to capture for a given interval of time, the no. of pulses triggered. time interval maybe : 1ms, 1 s, 5s etc. Been using the &, but couldn't understand if it is behaving as expected: -------------- while True: dwf.FDwfDigitalInStatus(hdwf, c_int(1), byref(sts)) print("Status:", str(sts.value)) if sts.value == 2 : # done break ------------ Not sure about the value to be compared here, as for 1 sec or for 5 sec, i am seeing the break in appx same time here. => Also tried with but i think it is not able to detect the drop in voltage for such short duration. Any help will be appreciated. Thanks, Rohit
  2. I am using a Nexys-4 DDR board which has an internal clock of 100 MHz frequency. I am using clocking wizard to generate a pulse of 6.78 MHz and duty ratio of 0.3. I am getting the correct result in simulations but when I observe the output on oscilloscope I do not see a proper pulse. It does not have sharp edges. I get a proper output for lower frequencies. I am unable to find out what is the reason behind this. I am using a 200 MHz bandwidth DSO and an x10 probe for measuring the output. Thanks, Yogita
