3.3.2.1 Checking the Linearity
In
the
following
test
the
output
voltage
of
an
AC
calibrator
is
measured
at
100
1:82
with
the
aid
of
the
10-V
insertion
unit
(Fig. 3-2). Care should be taken that the interfering voltage of
the AC calibrator determined by broadband measurement does not
exceed 200 uV. Otherwise a divider or lowpass filter must be pro-
vided at the output. In this connection please refer also to sec-
tion 2.3.2.2.1, where measurement of low RF voltages is described
in detail.
