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). see #http://cgi.ebay.de/1-St-HP-5371A-Frequency-and-Time-Interval-Analyzer_W0QQitemZ5817342262QQcategoryZ31337QQssPageNameZWDVWQQrdZ1QQcmdZViewItem 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 multiplicators.... 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 such devices. 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.
