[Test-Equipment] [MicroWaveandTestEquipTrader] Help ID NBS (aka NIST) Noise Source

[Stan, W1LE]

Hello Dennis,

This item looks to be only the power supply for the external noise source.
Someone else got the noise source.

It looks like the external noise source was connected to the
2 pin coaxial connector on the rear panel.

Noise head = noise source.

It is a piece of history and it will continue to look great in your museum.

Stan, W1LE
