Hi,
Nigel (Gandalf) has already answered this question very well, but as an
example I'm planning to use mine on a (quite old) Tektronix 602 display.
Other examples are Tek 620 (600 series, but some are storage) and HP

Dear timing colleges,
At CERN we are considering the possibility of using Ethernet as a real
time field bus.
We may use IEEE 1588 to distribute precise UTC and Ethernet Powerlink or
a similar home made product to guarantee

One thing that comes to mind, though I may be missing something here.
Ethernet is CDMA/CA; would you not loose phase lock during a collision
because of a corrupted carrier?

Looking at the IEEE 1588 while implementing in your own FPGA seems
like an odd choice. It is an option, but you could fairly easy cook
up something which fits your needs. It is not too hard actually.

First of all thanks a lot for your answers.
For a facility like CERN, I think that normal cabel
assymetries will be sufficiently low such that they would not
require explicit handling, unless you have higher

Hi Didier
I have a low cost DSO, the HP 54600 Jedi, and it has an X-Y mode (as well as a
Roll mode which emulates a strip chart recorder at very low time/div

All,
I tried it with a DSO scope in XY mode a while back (7201? - can't recall the
model, but it's 3-4 years old.)
After some playing about with the controls, it worked acceptably. The general
problem with it was getting

Over at TVB's place the other night, we tried the clock on his
TDS3000B-series DPO and it worked fine with a bit of knob-twiddling. The
cheaper TDS2000-series DSO in the recent Make magazine article photos also

have not looked closely, but I do not remember seeing X-Y mode on a DSO,
even though I am sure the high end models support it.

You could go on the HP reflector to see if anyone can help. However, Agilent
has about 90% of all of the old HP manuals (operating/service) in the
archives on their web site. They also have most of the old app. notes. There

Thanks Magnus, I guess I was dating myself :).
Pablo, is this going to be used for timing throughout the entire CERN site
or just instrumentation on 27km LHC?
If it's just the LHC then what about using an open fiber/copper
