The manual describes two probes.

One is just 3-4 feet of RG59 (or 6 or even 174) with clip leads
for ground and center conductor.

The other is a 10x probe. This has a 9 meg resistor in parallel with
and 8 or 10 pF ceramic or mica cap between the cable center
conductor and the clip. The cap is critical if and only
if you need reasonably flat frequency response, which that
scope may not be capable of.

To check scope frequency response, look at the waveform
on the video out of a DVD player playing a frequency
burst or sweep pattern.
