One thing you will run into on the 527 - They originally came out in the era of 5 MHz standards. The specs on the boxes only list 100KHz, 1 MHz, and 5 MHz as valid inputs. In reality, they will accept anything that's an integer sub-multiple of 5 MHz as an input (2.5 MHz, 1.66666 MHz, 500 KHz ...). The front end is an injection locked multivibrator. Check to see how happy yours is with a 10 MHz input. Most will run with 10 MHz and some multiples of 5 MHz sub multiples (like 5/2 x 3 = 7.5 MHz).
I agree, mine is happy measuring a 10 MHz signal, but prefers a 5 MHz reference - it has less noise.
