OT:
Although not all that one might want for calibrating scopes, a good start would be a reasonably good Rf signal generator, not necessarily PG or SG modules ...
Some sellers on eBay appear to consistently have "tested" (synthesized) Rf signal generators that go up to 1 or 2 GHz,
at reasonable prices. They often show photos on a spectrum analyzer of their RF signal generator in operation, as proof ...
If the SG is leveled, then it can check frequency response. There are
several 7000 series plugins (not 7xxx) that can do this, with
differing frequency responses.
That ought to allow you to use an unleveled SG to check -3db response.
However, you'd still need the TG 501 to check the time base, and the
PG506 to check amplitude.
In addition, the PG506 has some sub 1 ns rise time pulses that can be
useful in checking scope rise times.

For example { although there are many others } : EDIinc
Likely a better place to start than a vendor who shows no such photos...
