The specs says that the sine output requires a 390 pF cap to ground for
filtering. Still, it is rather distorted and ragged. It almost looks like
that they added the sine wave output as an afterthought and don't expect
anybody to actually use it. On the units that I have, it is useless
Hello, TimeNutters--
I understand that I will get less output jitter with a high quality
GPSDO than a Rb oscillator, but, even so, having a Rb unit
locked and disciplined by a GPS receiver appeals to me.
The one thing that I noted about the X72 is that the factory has
provided for a convenient
sounds to me that you have made up your mind to buy one, know it is not the
best, but look for support to buy it. What are you waiting for buy it. I
have a lab full of stuff I look at and ask what where you thinking when you
bought it and why 5?

I'm using an X72 for the timebase in one of my Philips 6680 counters
and it works great for that. For trimming I have a 30 turn pot accessable
on the front where the optional C input would be so I don't have to turn
the counter around to make adjustments. The X72 is powered 24/7 so
I don't
After one does the survey, how do you save the data so that Yellow
becomes Green ??
I just got another T-Bolt, this time a Rev E.

Hi
The lock input on the X72 appears to be intended for the I need to put it
on frequency stuff rather than doing a GPSDO. It's got a pretty coarse step
size for a GPSDO and the filtering tweaks aren't as extensive as you would
like.
For a Nixie clock, there's no need for the GPS if you have an

What is special / noteworthy about this rev? I have recently bought my
first T-Bolt (from another listmember, and I have yet to power it up),
and it's also a Rev E.

When talking about rev-E tbolts remember there are rev-E versions of the
standard tbolt and that there is also a Thunderbolt-E. The Thunderbolt-E is a
later model Thunderbolt with some small firmware differences and a 12 channel
GPS receiver. Also, it does not seem to have a temperature
Hello Bert,
I apologize for this very late response to your email. To be totally honest
I didn't really understand what you were talking about.
I am new at this and didn't realize I had on hand some of the equipment I
needed to do some basic testing.
My counter timer will resolve down to 2
Hi All,
This is quite a common oscillator, with variants used in a number of Racal
receivers or offered as high stability options for Racal counters etc, but
although the specs are widely available I've not found anything from Racal
that might be considered to be a user manual.

take your time we may be in the psec. arena but that does not require
instant response. Putting a D/M in front of your present counter is an answer,
but once the PC software is done on my unit it is a better solution because
it is a totally stand alone system and if you build my D/M it
Folks,
I know I am going to regret asking this but you only live once.
Please accept my assumptions during this question
Say we have a DMTD system that uses the same freq. for the common LO and the
F Ref and the FDUT 10 Mhz.
Further ... these oscillators are all synchronous, and in phase
