The horizontal sweep frequency is nominally 15,750 Hertz. That is 15.75 kiloHertz not MegaHertz.

It is easily measurable on a reasonably calibrated triggered time base oscilloscope. Remember frequency = 1/period. The 15,750Hz frequency equates to a horizontal sweep time of nominally 64 microseconds per line. Simply set the time per division setting to say 20 microseconds per division and when the horizontal frequency is correct, the sweep signal will repeat every 3.2 divisions.
