I think at these low frequencies, a digital source would be much better? A linear feedback shift register with 100MHz clock with a lot of post attenuation would give a perfect spectrum at 10 MHz. A simple CPLD could be programmed, or maybe even 74AC logic would do. You can make the register arbitrarily long, to avoid periodicity.
