Hi, I recently bought an Austron 2010B, a disciplined OCXO standard with
adjustable disciplining parameters, for use as a clean-up oscillator and
a decent fallback to my Ball MRT-H, a rubidium standard. I figured that
the quartz standard's 1 Mhz and 5 MHz outputs are fine---the former is
exactly what my Truetime 814-149, a time code generator, needs for
eventually providing PPS output to my SPARC-based NTP server, and the
latter can be doubled, amplified, and distributed, all with a single
distribution amplifier unit, for use as a timebase for transmitters and
lab instruments. Only later did I realize that for some bizarre reason,
all of the outputs are square wave, not sinusoidal! Great.
Any ideas on the likely reason that the unit was engineered with only
square wave outputs? Obviously this will render division to PPS
trivial, but all of the applicable equipment that I've encountered use a
sinusoidal reference, not a square one, so it doesn't seem prudent to
exclude sine. And naturally, what is the most prudent course of action
in this situation? I'd rather use something prebuilt than building my
own converter, but all the distribution amplifiers I've looked at lack
such a conversion feature, and I'm unsure whether plain square to sine
converters are suitable for such time/frequency metrology applications.
Thanks in advance,
Ruslan
