Keep an eye on this listing. We are going to try
to characterize the standard and display the Allan Variance.
This standard was rated at 1 part in 10-8th per day. It was normally
not used internally with this unit but had an external 5mhz standard
which was used most of the time which was the 10-9th a factor of 10
better than the internal standard.
This was the mainstay of the navy, the R-1051B and the
air force had the C model. Unbelievably complicated and weighs 90 lbs
for a solid state unit. However, they are still in use today! (G&H models)
today because they are so rock solid when it comes to SSB reception.
The 5mhz input compared the frequency to the internal
standard and there was a flashing neon bulb and the ET's tried to get
the internal standard to almost agree with the external standard at
something like 1 flash/ 5 seconds.
This unit has been factory refurbished and it comes
in a sealed anti-stat bag from the Navy's Metrology Lab.
Its Military Part Number is AG-6625-078-4713
