HP5061B Modulation Adjustment

Two volts pp of
10 mc rides on that dc. We were operating unterminated on the output
of the mixer.
As long as the diode drops are stable, we can still see phase changes
to a fraction of a picosecond. A picosecond is the delay in an 8 mil
length of RG58 cable. (1,500 ps per foot) We have one DVM with a
resolution of 1 μ V dc.
