Hi Magnus and the others in the group,
thank you very much for your comments and the help!
I had a look to the counter at the seller, propably really ok, but its at ebay
already above 1000 $, and he believes to get much more.
(We will see soon where it ends).
In Germany such devices are rare and very expensive, as there are some
dealers buying all the good equipment and reselling them to companies with
Even for a really defective 5371A, showing fatal errors on RAM,
mathunit and others, they ask for at least around 600 $.
That's not my collar size....
This forces me to try to develop a very high speed gating device with
d-flip-flops as ripple counter, capable to work below few ns, best would
be to count up to 500 MHz pulses (1ns), but unfortunately I am already
an old codger who liked to work with analogue rf signals, not liking all
the digital devices.
The point is, I do not find gates capable to work well beyond 30, 40 MHz.
I there somebody having a helpful idea how this could be solved?
PS: I had a look to the internal h/w of the hp 5371A, the ocxo is a
normal hp 10811-60111 in, I thought to find a higher qualified type in
No, I am not watching all that illnesses about jamming gps etc.,
because I think that this is good calming down people, but this would
not stop informed guys at all navigating to the target...there are other
ways. So what.
Hello Robert in Zürich, I hope to meet you again, viele Grüsse in
die Schweiz, nur etwa 70 Strassenkilometer von Salem.
