Re: Replacement probes
Hello Stan,toggle quoted messageShow quoted text
Those that you say were crimped are probably for P610X probes. I never tried
to repair those cables, I only replaced them. The P610X were modular and you
could buy box, cable and tip. I do not think those probes were pinnacle of
Tektronix' quality, connectors that mated to cable were pretty poor. It
happened more then few times that probe would quit working again shortly
after cable replacement 'repair'. Mating and unmating cable and end piece of
probe would fix the problem but that was a short term solution, the end
piece needed to be replaced. I found it overly expensive to repair those
probes and at one point I started to buy new probes when an old developed
trouble and just saved old ones to use as spare parts.
The cables that I tried to repair were for P600X. Cable ends were spot
welded and soldering worked with lot of scraping and use of Aspirin as flux.
That soldering taught me to treat probes with respect.
I am not really surprised that Tektronix did their own cable, a probe cable
does not have other applications. The Beldens of this world would not design
and make 10000 yards of probe cable just for Tektronix and hp. Maybe now a
common cable manufacturer might use one of their machines to make one run of
customer designed cable and price it accordingly, there seems to be more
custom runs now than there was in 60s.

Back in the "old days" (before about 1980, or so), Tek used to manufactureTek
manufactured, they could not find suitable cable on the market from otherprobe,
you probably have noticed that the coax used for the probe cable has aVERY
fine center conductor and you can't really solder to it either. It iswire
with distributed resistance and the connections at both ends are crimped.out
