Operational
Modes
Continuous
Operating
as
a
standard
VCG
(voltage-controlled generator)
frequency
of
5012
OUTput
is
determined
by
front panel
control
settings
in
conjunction with
VCG
IN
put
signal.
Output
of
internal
sweep
generator appears
at
SWP/GCV
OUT
connector.
Triggered
Only one complete
cycle
of
output
appears
at
5012
OUT
connector
for
each
pulse applied to
TRIG
IN connector.
Gated
Same
as
Triggered
mode
except
that
output
oscillations
continue
for
duration of
gating
signal
applied to
TRIG
IN
connector.
Continuous
Sweep
Main
generator
is
swept by
internal
sweep
generator so that
frequency
of 5012
OUTput
Is
swept from
a
low frequency
established
by
front panel
frequency
controls
to
a high
frequency determined by
SWEEP WIDTH
control
setting.
Sweep
rate
is
determined
by
SWEEP TIME
and
VARIABLE
controls.
GCV
OUTput
(generator-controlled voltage) ap-
pears
at
SWP/GCV
connector.
Triggered
Sweep
Same
as
Continuous
Sweep
mode
except
that
output
is
swept only once
for
each
pulse applied to
TRIG
IN con-
nector.
During time between sweeps,
main
generator
oscil-
lates
at
low frequency determined by frequency
control
settings.
Sweep
and Hold
A
gated
sweep
in
which
the
frequency output
is
held at
maximum
at
the
end
of each
sweep
for the
duration of the
gate
signal at
the
TRIG
IN connector.
Between
gate
signals,
the
output
is
the
low frequency determined by
the
frequency
control
settings.
