The Tinsley 5646 was designed in the late 70s based on LM399 reference
IC. You can expect long term stability similar to a 34401A multimeter.
The right side circuit is normally off and switched on only for
calibrating the left side output which is continously powered. That
reduces the drift a litt
The Cropice only has 1.0 and 1.018etc volt outputs, so only of use as a
transfer from stan dard cells.

Both offered by the same vendor who is selling the Guildline standard cell set.
Both solid state voltage references. He's priced the Cropico Electronic
Standard Cell higher than the Tinsley Voltage Standard.
Does anyone have guidance as to their quality and relative merits?
Thanks
