I am trying to measure the clock Signal of a positioning module in SSI mode using an oscilloscope. The Problem is that with a high Transfer frequency let say 1Mhz there is some missing pulse in the clock Signal I have been able to see it with my Simulation. How can I measure that with an oscilloscope? Is there someone who has an idea how I can do that?

many thanks

It depends on how frequent the missing pulses are present in the simulation and what oscilloscope you are using. If the missing pulses are frequent you should be able to detect them on your oscilloscope. If your oscilloscope is a digital storage one, you can set it to sample for a long period, you can then slowly investigate the capture manually to see the frequency. You can also try using math functions on your oscilloscope to detect the missing pulse; however, if the missing pulses are infrequent this will be tedious to do.

If you have access to a spectrum analyser that could also be potentially used to detect any anomalies in your clock signal.

Depending on your background/expertise, you can also write some code on a microcontoller/fpga/etc.. which monitors the clock. You will specify the clock frequency expected, the code will sample the wave and increase a counter on every missed pulse. See the counter result and you will know if any pulses have been skipped.
