GENERATOR
The
generator
drives the item
under
test (IUT).
The
drive
signal
parameters are
shown
in Fig

drive
parameters.
TYPE
Selects
constant
voltage
or
constant current
drive:
•
[voltage]
Constant voltage
drive:
With
MONITOR ENABLE set to
[monitor
off] the amplitude of the
generator
output voltage is held at the
V
AMPL value.
With MONITOR
ENABLE set to
[monitor
VI, target
=
V
AMPL] the
generator output
is varied between
GV and V
LIMIT in an attempt to hold
the
analyzer
VOLTAGE
1
input
at
the
V AMPL
value.
With
MONITOR ENABLE set to
[monitor I, target
=
I AMPL] the
generator
output is varied between
OV and
V LIMIT in
an attempt
to
hold
the analyzer
CURRENT input at the
I AMPL
value.
•
[current]
Constant current
drive:
With MONITOR
ENABLE set to
[off] the
amplitude
of the
generator
output
current
is
held
at
I AMPL
value.
(Set up
the drive current
parameters from the
[GENERATOR Conti
page.)
With
MONITOR
ENABLE
set
to
[monitor VI,
target^
V AMPL] the
generator output is
varied between
OmA and I.
AMPL in an
attempt
to
hold the
analyzer VOLTAGE 1
input at the
V AMPL
value.
With
MONITOR ENABLE set to
[monitor I,
target= I AMPL]
the
genecator output
is varied
between OmA
and I AMPL
in an attempt
to
hold the
analyzer CURRENT input
at the
I AMPL
value.
FREQ
Frequency of
generator output.
This is
selectable in the
range 10pHz to
32MHz. To
vary the frequency
progressively,
use
SWEEP.
V. AMPL
Constant voltage ac
amplitude, in the
range
0V to 3
V rms
(/"<
10MHz) and
0V to IV
(f>
10MHz).
V. BIAS
Constant
voltage dc level, in the
range
-40.95V to
4-
40.95V. Used
for
setting the
quiescent operating point
of the
IUT
or for
nulling
a dc
offset.
