Features
The 7B80
Time-Base
unit provides calibrated
sweep
rates
from
5
seconds
to
10 nanoseconds and
triggering to
400
megahertz
for
7700-, 7800-,
and
7900-series
oscilloscopes.
A
X10
Magnifier increases
each
sweep
rate
by
a factor of
10 and
a
VARI-
ABLE
TIME/DIV
control provides
continuously
variable
sweep
rates
between
calibrated
steps.
Variable hold
off
and
alpha-
numeric readout
are provided. Also,
when
operating
in
the
AUTO
TRIGGERING MODE,
a
bright baseline trace
is
displayed
in
the absence
of
a trigger
signal.
The 7B80
can be operated
as
an independent time
base or
as a
delayed-sweep
unit with
a
com-
panion
delaying time-base
unit.
