Hi,
I recently purchased a surplus Trimble Thunderbolt and would like to
get it going. The 24 volt units have a fairly wide range of
acceptable voltages. The only power supply specs I can find for mine
specify +5, -12 and +12. No min-max is specified. I have a power
supply that has +5, +15
Hi
Ideally you would like 12 volts +/- 0.1 V, but +/-0.5 will work. 5V +/- 0.25 is
best, but +/- 0.5 should work ok. -12 +/- 1V is ok, you can get away with
something looser. What ever you have should be well regulated, at least on the
+12 line.

Hi
Ideally you would like a linear supply (not a switcher) on the +12 and +5.
That's not always very easy. If you are not worried about phase noise, the need
for linear regulation is reduced. Depending on the switcher, there may be some
impact on ADEV, but that's not real common.

Many low cost triple output power supplies are designed to power digital
circuits (e.g. +5V) with maybe some RS-232 or analog circuitry (+-
12V). Since the only 'important' voltage is +5, that's the only
voltage that's regulated. The others are designed to be within maybe 5%

The simple answer is that there is no regulator in the TBolt between the OCXO

The common suggestion is to run a ~ +15 supply and regulate it to +12 at the

Hi Paul,
Yes, I've read that page a couple of times, but it doesn't say whether

would be well regulated. I can pretty well guarantee that the ATX
The +12VDC supply (internal to the sealed oscillator) supplies both the oven
