It won't change.
The peak value of the partial voltage pulse will be smaller (depending on the partial voltage ratio), and the pulse width, period and waveform will not change.

Resistance has no voltage drop, a waveform through the resistance and then to your measuring instrument will affect the amplitude of the waveform, it may be that your measuring instrument itself has impedance, after the resistance of the measurement result is equivalent to being divided by two resistors, the greater the resistance you series the amplitude of the measurement will be smaller, and it is also related to your frequency. Series resistance and instrument impedance may be different at different frequencies.
