The features
of
the
TAS
475 and
TAS
485 Analog Oscilloscopes are briefly
described here to help get you acquainted with the operating systems. •
This oscilloscope uses a combination
of
front-panel buttons, knobs, and
on-screen menus to
control its many functions. The front-panel controls are
grouped according to function:
vertical, horizontal, trigger, and special.
Within each group, any function adjusted often, such
as
vertical pOSitioning
or the time base setting,
is
set directly by its own front-panel control.
AUTOSET
The AUTOSET button provides you with a usable, triggered display of a
signal applied to an input channel. Many instrument controls and menus are
set
to
a pre-defined state, providing you with a known starting point for your
measurements.
Menus
Those functions for which control settings changed less often, such
as
vertical coupling and trigger mode, are set indirectly. That is, pressing a
front-panel button, such
as
VERTICAL MENU, displays a menu of functions
at the bottom of the screen
related to that button. (For the button VERTICAL
MENU, the menu displayed contains functions such as coupling and band- •
width.) The buttons below this main menu select a function, such
as
cou-
pling and displays a sub menu of settings for that function, such
as
DC,
AC,
or GND, at the right side of the screen. The buttons
to
the right
of
the menu
select a setting, such as
DC.
General Purpose Knob and TOGGLE
Some menus assign the General Purpose Knob
to
a selected adjustment.
The method
employed
is
the same as for selecting a function, except the
final selection
in
the side menu causes the General Purpose Knob to adjust
some function, such as the position of measurement cursors on screen.
Pressing the CLEAR MENU button clears the assignment of the General
Purpose
Knob except when assigned to adjust cursors or delay time.
The
TOGGLE button works in conjunction with the General Purpose Knob
when positioning cursors. Each press of the
TOGGLE button switches
which cursor
is
active, and therefore controlled by the General Purpose
Knob.
Save/Recall Setups
You
can store up to four complete front panel setups in memory. Once you
complete a complex setup and then save it
in
one of the four memory loca-
tions, you can retrieve it at any time. Saved front panel settings
do
not
include the assignment
of
the General Purpose Knob. •
