Operation
of the
Function
Generator
(
Cont'd)
The frequency
of operation
will
be approximately
IkHz.
Variations of the
Frequency
Dial
enables
signals
within the
frequency range
of
lOOHz
to
lOkHz
to
be
generated.
The
frequency does
not
change when
the
Function
Selector
is
used
to
produce
the
three different
waveforms.
The
output amplitude
can be
adjusted via the
Amplitude
Control from
O.IV
pp
to
lOVpp
from
the
main
output terminal,
and
from O.Ol
V
p-p
to
1
,0V
p"p
from the 0-1
V
output
terminal.
A
TTL compatible
output
is
permanently
available from the terminal
marked
TTL on
the
front
panel.
The phase
relationship
between
the
TTL
output
and
the other
waveforms
is
shown below
Offset voltage
can be superimposed on
the
output
waveform
by
pulling the Offset
Control out
until
it
clicks
and
then rotating the control either side of the centre
point of
its
rotation.
Pushing the
knob back
in
renders the control in-operative.
By
setting
the
symmetry
controls
as
shown below
the
effect
ofvariable
symmetry can
be seen;-
