Cable question: I assume that won't be the problem. I use my 26dB
Trimble timing antenna with RG-213 because of the low loss (and the low
cost). Before that I had 15 m (45 feet) of RG-58 combined with a car
roof magnetic patch antenna in use without any problem. Any 50 Ohm cable
can be used,

Hi Everyone!

@Azelio: Yes, (like Bob told) it's the phase lock, that locks the two
maxima. Actually the counter is able to look between the 60ps spaced
towers, have a look at the pictures in the first mail of this thread.
However, there is a smallest time value the counter can determine, but
it is much

Yes, I wondered what the histogram would show when using the
2-maxima-Z3805 signal as a reference for the SR620 counter. Would the

As far as I can see the PLL loop filter (SR620) has a corner frequency
of about 33Hz. My HP counter 5385A has simply a switch to toggle between
the external source and the internal osc.

Most modern counters have an internal oscillator that they
So let's have a look into the machine... and what do we see? There's a
nice little Symmetrcom oven, with the sign reading 5.000 MHz - bingo!
May be there's a time saving way to determine the energie of the sub
harmonic: using my spectrum analyzer. It tells me, that there's a 5 MHz
I'm impressed - but what law is behind this?

60 db isn't to bad a number. More or less:
100 ns - 100 ps is 1000:1. 20 log of that is 60 db. 100 ps to 60 ps is about
4.4 db. That would sum up to -64.4 dbc. The main gotcha is that you *might* also

That's what my fan does (over abot 15min), but it doesn't stop

Yes, I guess, signal strength is essential. My holdover uncertainty is
(after 1 weeks) about 1 to 2us.

Your 21 ns for 1PPS and T1 does not look too bad, but the satellite

You can easily check the 5V by measuring at the open antenna plug. When
plugging the antenna, total current consumption should increase by about
10mA or so.

Fellow time-nuts,
I am new in this mailing list and a little bit unfamiliar with it, so I
