Ah, I had forgotten about the "Nanny knows best" feature of the JDSU (or should that now be Viavi? ).
Of course, when typing the above, I was thinking of my Tester 301C.
Indeed so, the Viavi is replacing the JDSU, but not sure where 'they' are with the roll-out stage at this moment in time ??
Aah - the 301C - a king amongst kings of the TDR digital readers, only matched (or slightly surpassed) with the old oscilloscope, who's name, make and model I couldn't tell you ??. They were almost obsolete by the time I'd begun my faulting career and only the old sweats would have them ... but boy could they detect a HR
anywhere along the circuits length ... unlike the digital TDR's that are either good at short distance, but not long distance ... or vice-versa.
