Hi Take a careful look at the specs on the SA.31M before you buy one. It may or may not be what you are looking for in terms of stability and temperature range.
We do live in a “no free lunch” sort of world. There will always be tradeoffs in any design. It’s an amazing part, they did a lot in a small package with very little power. There were tradeoffs. The CSAC behaves like a gas cell device (similar to a Rubidium) rather than a beam cell device. That’s because it *is* a gas cell that just happens to use Cs rather than Rb. The performance of a 5071 comes more from the beam cell approach than from the Cs in this case.
