Gary, In general I've found that test gear that accepts 48VDC +-xx were made for telco's for use in central offices.? The model # usually has a prefix or suffix. These ran off the 48VDC power plant.

In case there's anyone else still confused about tip capacitance vs frequency, I've again posted up the Rp and Xp plot from Tektronix for one of their old x10 scope probes. If you look at the Xp

Beautiful work David. I’ve downloaded it and will print it out shortly (I prefer paper). I’ll also post a link to it in the thread over at Antiqueradios. Thank you again, Leon…

Of course the shunt capacitance (Cp) is going to change (reduce) up at VHF and UHF because the bulk of the series tip capacitance is in series with a lossy transmission line. There is some shunt tip c
