Ozone Hole near South Pol

Hi,
I am playing with some switch mode power supply circuit and would like
to inspect its influence to other equipment. I only have an old
fashion analog ocilloscope and want to measure the first few harmonics
(50, 150, 250 Hz probably). The only solution I can think of so far
is to build a few band pass filter and measure the magnitude one after
another one.
Do you know if there is any smarter solution than this? I have got a
feeling that I may take advantage of the X-Y input. Any idea whether
I am on the right track?
