DESCRIPTION
The
RG
501
Ramp
Generator produces an
adjustable
10
V
ramp,
either
positive-going or negative-going, with
selectable
and
variable
durations
from
10 s to
10
a<s.
A
TTL-compatible
gate signal
coincident with the
ramp
duration
is
provided
at
the front panel.
The
RG
501
has a
full
set of
oscilloscope-type trigger-
ing controls providing
normal
or
automatic
triggering,
slope
and
level
selection,
and
triggers
from three sources:
line, internal,
or external via
a
front
panel
BNC
connector.
The
RG
501 operates
in
a
TEKTRONIX
TM
500 Series
Power Module
only.
It
is
completely compatible with other
members
of the
system
in
terms
of signal
interconnec-
tions.
The
RG
501
is
designed
to
operate
in
ambient
temperatures
between
0°C
and
-l-50°C.
It
can be
stored
in
temperatures ranging from
—40° C
to
+75°
C. After storage
in
these temperatures, allow the
RG
501 chassis
to return
to
room ambient temperature before applying power.

to
the
RG
501 by pulling
out the
power
switch
knob
of

Even though the
RG
501
is
fully
calibrated
and
ready to use,
the functions
and
actions of
the controls
and connectors should
be
reviewed before
attempting to
use
it.

while
all
the
rest
are self-cancelling actions.
Note
also that
the
