These two keys work
in
conjunction
with the STEP
Function
key.
These keys repeat while they remain pressed.
After
a
parameter
is
set to the step
function mode, and
the STEP indicator appears
in
the
display field, this
key
increments
the
parameter
by
the step
value previously
programmed.
After
a
paraneter
is
set to
the step function mode, and
the STEP
indicator appears
in
the
display field, this
key
decrements
the parameter
by
the step
value previously
programmed.
These keys are used to position the bright digit within
a
display field and
to
increase
or
decrease the bright
digit value.
All four
keys repeat while they remain
pressed. The
function keys
are used to
move
the bright
digit to the
desired display
field.
Increases the bright-digit value.
Moves the bright digit one digit
to the left.
Decreases the bright-digit value.
Moves the bright digit one digit
to the right.
A
push and
hold key that displays
the Uncal
and Reject
Entry status codes
in
the MODULATION, FREQUENCY, and
AMPLITUDE display fields.
A
push-on/push-off
key (with
a
corresponding
RF
OFF
indicator
in
the STATUS display
field) that
enables
or
disables the output
of the Generator.
A
BNC
connector
for input of
a
1V peak,
external
modulation
signal.
A
BNC connector
for input of
a
IV peak, external pulse
modulation
signal.
A
standard
RF
connector
at the output
of
the
Generator.
A
push-on/push-off detent switch
that
applies
Line
power
to the
Generator.
These
different
methods
all
accomplish
the
same
result
but use
different
approaches
for
different reasons.
One
is
to
reduce
the
chance
of error during
complex
test
procedures
that
require
continuously
resetting
parameters.
Another
is
in
the case
when
a
test
is
partly
under
remote
control
and
only
some
of the
parameters
require changes.

FUNCTION ENTRY
Changing
an
instrument parameter with the
Function Entry
method
consists
of:
Selecting the function to
be
changed
Entering
the
new
numerical value
of the
parameter
Selecting the
units
of the
numerical value (megahertz,
millivolts,
etc).
