There are at least three advantages for external operation.

1.	 The HP turkeys didn’t make EFC available on the HP 5370B which totally baffles me.

2.	There are better lower noise and far more stable voltage references for powering the oscillator and EFC.

3.	You can put the oscillator in an insulated box for better temperature stability.

All of this will allow you to max out your oscillators cabilities.
