It can be altered, but only by 50ns. You can invert the phase of the osc
sense (feature not available on Thunderbolt-E or Thunderbolts built before
March 1998). Use the '^' command in Lady Heather.
The PPS output is synchronous with the 10MHz signal

One way of reducing the effective noise/jitter on the PPS signal when
using it with the 5370 to measure the instability of a source with
respect to the Thunderbolt is to use the PPS to ARM the 5370 whilst the
10MHz from the thunderbolt starts the 5370 and the source (or a
frequency generated b
Ah ha! That explains the changing numbers I see on the 5370B (jitter), and
explains why I see no change on the scope other than the jitter. Reading
the manual, I don't see any clear explanation like what you just gave me. I
see my mistake in manual interpretation but not until after reading your

No, it doesnt.

Hello all,
I'm trying to adjust the time between the leading edge of the PPS square
wave and the 10MHz zero crossing outputs on a Trimble Thunderbolt. The
manual seems to indicate the cable delay compensation setting will do this.
As I understand things, this is also called the "PPS Offset" in th
