Three

are
available
for

The
attenuation

of
the
100-V
insertion
units
is
automatically
taken
into
account
by
the
URVS and therefore need not be entered.
The
low
reflection
coefficients
of
the
100-V
insertion
units
are
worth mentioning, since they render the insertion units particu—
larly suitable for precision measurements on coaxial 50-9 and
75-9 systems.
