Hello Pierre-François
A point of personal interest in your email - - The noise of the fan in the
5070B, this would appear to be a problem with a number of the older items of
Hewlett Packard, and other manufacturers.
The items are usually fitted with a Papst fan,with a high throughput of air
running from the power line. Has anybody tried to replace these fans with a
more modern type (12/24 volt). I'm sure the designers were being very
proper, but I cannot believe that a counter should require such a large
volume of air moving through it ? I have an EIP 545 Counter and an HP 5335A
which both have Papst fans and are very noisy
Any ideas on this.
Roy

Subject: [time-nuts] 5070B once more....
Hi The Gang,
I've revitalized my 5070B I got few years ago and since a week or two it
has seen again passing into it few electrons after so long... lol...
Now I'm wondering which software I could use to grab data from it to the
PC and then to analyze the buffers to see the stability of my rubidium
source synchronised with the 1pps coming from the GPS.
I've on a dedicated PC (XP) a GPIB/USB adapter for this application. Could
you tell me which sw I could use to do this?
I want to avoid to reivent the wheel by writing another piece of software.
The 5070 (A or B) is really a great piece of hardware, I love it, exept
its noisy fan...
Very good idea to invite Dave Chu to join the group, I'm sure his heart
will vibrate to see that his baby is still alive for a very long time...
;-))
Best 73's to all of you.
pf, F5BQP
