[time-nuts] Cesium beam tube low-frequency coil

[Stewart Cobb]

The HP 5061 manual describes the use of a low-frequency coil built into the
beam tube to check that the basic functions of the beam tube (emitting and
detecting cesium atoms) are okay.  This check splits the debugging problem
for a failed clock approximately in half.

FTS/Datum made replacement cesium beam tubes for these clocks, as well as
similar tubes for their own cesium clocks. Does anyone know whether their
tubes have an equivalent LF coil? And if they do, what are the appropriate
frequency and amplitude to drive the coil for the test?

Cheers!
