Will this scope do the job

No, the bandwidth to which I am referring is vertical bandwidth. If it's at least 5 MHz you are okay. The 'squiggle' means Hz. It's a tilde and is meant to look like a little sinewave cycle.

I can't see the probe in the pic, too dark. The probe you want is needed to avoid screwing up the circuit you are measuring. The usual test leads won't do.

I would recommend you scrap this and get a modern unit with nice probes; these are available cheaply enough. In fact an old Tektronix tube unit should go for under $50 if it's not a rare model or one of the big jobs.

Some of the main problems in those old units are sweep nonlinearity and lack of calibration, both horizontal and vertical. If you view a sinusoid you will see it compressing toward the right, as the 'sawtooth' imperfections become more apparent. And you have no idea of the frequency, nor of the the amplitude, without some kind of calibrator. In addition, synchronizing the sweep so as to see a steady display is often a challenge.

Having said all that, you can, if you are careful, use it for a lot of things beyond its basic capabilities. You just have to realize its limitations and work around them.
