Paul,
Take a look at page http://www.leapsecond.com/pages/tbolt/photos.htm
The fourth pic down in the right column shows the power connector soldered
directly to the PCB (upper left edge, by C6).
If your power 6 pin header is in the same spot then it is highly probable the
pinout is identical.

Hi,
Long time lurker here, getting ready to upgrade to a Trimble Thunderbolt
for my 10 MHz reference. I have a question about the power connector pinout.
I acquired a 48051-61 plain PCB presumably requiring +5V, +12V, -12V. I
have no documentation. Mine has a 6 pin header, NOT the Molex conne
Hi
As noted in many posts, 1/F noise is dependent on a number of
operating parameters. The first thing to do would be to understand
your use case. Testing under one set of conditions may not be
useful for use in other conditions.

What would be a (very) good lab setup for the 1/f noise evaluation? I'm
talking about BJTs and JFETs.
What instrumentation and power supply are needed? How not to measure in a
wrong way - like 1/f noise in the instrumentation or the power supply
circuitry? Active collector/drain current sources vs
