3.2.2.1 Checking the Linearity
In
the
following
test
the
output
voltage
of
an
AC
calibrator
is
measured
at
a
frequency
of
200
kHz
with
the
aid
of
the
RF
probe
(Fig.
3-2).
Care
should
be
taken
that
the
interfering
voltage
of
the
AC
calibrator
determined
by
broadband
measurement
does
not
ex-
ceed
200

Otherwise
a
divider
or

filter
must
be
provi-
ded
at
the
output.
In
this
connection
please
refer
also
to
section
2.3.2.2.1,
where
measurement
of
low
RF
voltages
is
described
in
detail.

voltage
In the following test the Output voltage of an AC calibrator is
measured at a frequency of 200 kHz Voith the aid of the RF probe
3-2). Care should be taken that the interfering of
the AC calibrator determined by broadband measurement does not ex-
ceed 200 uv. Otherwise a divider er lowpass Filter must be provi-
ded at the Output. In this Connection please refer also to
section
2.3.2.2.1, where measurement of los RF voltages is described in
detail.
