5 or 10 MHz should perfectly work. The nominal input range would be actually 2 Vpp at the input connector, respectively about 10 dBm. You should use an oscilloscope to check the real input voltage, both at the input connector and the ADC inputs.

P.S.: The signal generator must be able to drive 50 ohm, of course.
