will also look better than it really is, and for the same reasons. (Some people have even reported similar behavior with cesium standards, although I don't see how that could happen. There aren't supposed to be any first-order temperature effects in a CBT, and I'd think that any lower-order effects would be way beneath the tube's flicker floor...)
The 5061 had problems with microwave field leakage known as the top cover effect (see papers by DeMarchi.) This is at least a possible mechanism for injection locking 5061's. The 5071A has a completely different microwave assembly without leakage problems. The 5071A outputs have very high reverse isolation. Tests showed that there are no detectable systematic environmental effects in the 5071A (whatever ones there are fall below the noise).
