[time-nuts] BVA Oscillaotrs

[Martyn Smith]

Hello,

Today many manufacturers are producing 10 MHz oscillators that offer many
advantages over BVA.

Phase noise of <  -116 dBc @ 1 Hz with a -175 dBc noise floor, ageing of 5 x
10E-9 per month and a G sensitivity of 5 x 10E-11 /g in all axis is
available on a new product.

Also the short term Allan variance is in the low parts in 10E-13 for one
second.

It seems to me the only real advantage of BVA is the long term ageing and
this can easily be sorted out by locking to a superior standard.

Best Regards
