Here is the display of my oscilloscope when the input is a 1000 pulse per second output of a time-code generator. (The time-code generator is a device that locks to the 10 MHz output of an atomic clock and produces 1 Hz or 1 KHz pulse trains as well as human readable time synchronized to the atomic standard.)
I imported the data and plotted it along with its periodogram.
Notice that only the odd harmonics are present.
Here is a mathematica notebook that simulates this.
