Sorry. I forgot that important piece of information.
It was measured on a Tek 485 set to 50 ohm input impedance. My other
standards are 50 ohm output impedance and I presume that the Z3805A is as
well but I do not know.

Did you measure this while terminated into a 50 ohm load? (or whatever the
characteristic impedance is)

I obtained a Z3805A from one of our popular far eastern sellers on ePay and
just got around to hooking it up to power and antenna. It appears to be
working correctly, comes on frequency, 'locks', and matches my other
standards well, at least in frequency.
However, it is not a sine wave. It is 'sine wave like' but obviously
distorted with the upper half of the sine wave somewhat flattened but
nowhere near as much as the bottom half.
Is this normal?
Thanks in advance.
