IMSAI Guy goes through the fundamentals of rise time and bandwidth relationship, explains why 0.35 has become 0.45 and then uses LBE-1321 for scope evaluation in part 2 of his video

There is a USB control trim with +-5Hz range. It has quite a narrow bandwidth though so not suitable for FM.
We are getting ready to release a small batch of low phase noise OCXOs:
-115dBc/Hz at 1Hz offset
-170dBc/Hz noise floor
30 femtoseconds jitter in 1Hz to 100Hz range
Two 10MHz outputs with +11dBm 50ฮฉ SMAs
No significant spurs
Mains powered
Who is interested?
Now this is what I call a quartz crystal
Yes โ this all depends on whether absolute accuracy, longterm stability, signal purity, portability or agile output is the major goal.
Rubidiums have few things to watch out for: they can be up to 1E-9 off frequency (but can be manually trimmed) and significant spurs due to the way they operate.
