For the THS series, the maximum voltage difference between the grounds
of the probes must not be greater than 30V.

Yes, the THS730(A) bandwidth is 200MHz.

If one channel is enough, he could use both probes together in
differential mode, and the voltmeter input may be used as trigger on a
different signal.
