transmitter
frequency
to
each
of
the
values
in
the
table
on
Pages
5-27
to
5-29.
Note
the
reading
on
the
AC
Voltmeter
at
each
frequency.

Use
the
AC
Voltmeter
readings
and
the
table
on
Pages
5-27
to
5-29
to
check
the
flatness.
This
is
best
explained
by
the
following
example:
If
the
frequency
is
20
Hz,
and
the
AC
Voltmeter
reading
in
step
12
were
71.0
mV
-
Look
up
71
mV
in
the
Vq^.
column,
then
check
the
20
Hz
column
for
the
allowable
voltage
range
when
the
HP
4934A
is
connected
to
the
AC
Voltmeter.
If
the
reading
in
step
10
is
within
the
79.7
to
63.3
mV
range,
the
20
Hz
check
would
be
good.
