Set the
generator
parameters to
provide
a
suitable
drive
for the
item
under test,
(IUT).
Remember that
the drive
specified must
satisfy:
«
the
generator output
capability,
»
the
rating of
the IUT, and
«
the
analyzer
input range.
In
the
present
example the IUT
is driven at
a frequency
of'
15.9kHz At
this
frequency
the impedance
of the
circuit is
approximately
707Q,
and a
drive amplitude
of
IV
(applied both to
the item
under test
and to the
analyzer
VOLTAGE 1 input)
develops a
drive
current of
approximately
1.4mA. The
drive and
expected test
response
are thus
well within the
capabilities
of the generator
and
analyzer.
The
generator
set-up
sequence is:
Press the GENERATOR
hard key...
...to select, the
[GENERATOR]
menu. The titles
of the parameters
that can be
set up appear
over
the soft keys.
