Inexpensive precision frequency reference
AADE Precision Frequency Reference.
is better than 0.1 parts per million (1Hz at 10MHz)
with long term accuracy of 1 part per million (1Hz at 1MHz)100_0100.jpg (21354 bytes)
Switch selectable output frequencies of
Output is .5V p-p square wave into 50ohms
I do not have long term experience with this unit but it uses the same precision oscillator used in my line of frequency counters.
It now reads 10,000,003 Hz. 3 Hz drift at 10MHz after 4 years (0.3 parts per million)
Not a bunch of lawyer garbage.
