Hi again, I do have a HC manual for an older 105B (bought about 30 years ago) but can't access it at the moment.

Try CALLING them (telephone) on Monday and talk to an Engineer, NOT their sales department. I haven't talked to Artek Media, but > they don't list it. eMail Dave. > That's why I repeated the test with the signal generator - to see how it > responded to an improperly terminated cable. It will depend on the cable Z, source Z, and termination Z. > The old manual doesn't list an impedance either. However, the responses > of the 1 MHz and 100 KHz outputs are consistent with a 50 ohm > impedance. The 5 MHz looks more like about 7 ohms based on an > open-circuit reading of 86 and a terminated reading of 76. The circuit > check is basically a peak-reading meter. A 43 ohm resistor in series > with each output might be very interesting. But I'd rather find a > schematic first. Try it. You won't break anything. >> I'm not so sure. >> > I'm not at all sure. :-) > > Ed Best, -John =============== _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
