conductor in the power cord, is essential for safe system operation.
The logic scope is grounded through the power cord. To avoid electric shock,
plug the power cord into a properly wired receptacle where earth ground has
been verified by a qualified service person. Do this before making connections to
the input or output terminals of the logic scope.
Without the protective ground connection, all parts of the logic scope are
potential shock hazards. This includes knobs and controls that may appear to be
insulators.
Use only the power cord and connector specified for your product. Use only a
power cord that is in good condition.
To avoid fire hazard, use only the fuse specified in the parts list for your product,
matched by type, voltage rating, and current rating.
To avoid personal injury, do not operate the logic scope without the panels or
covers.

To prevent overheating, keep the logic scope ventilation holes free from
obstruction.
If you suspect the logic scope is damaged, have it inspected by a qualified

Conventions
This is the User Manual for the TLS 216 Logic Scope.
Section 1 Getting Started familiarizes you with the operation of your logic
scope.
Section 2 Operating Basics covers basic principles of the operation of the logic
scope. The topics covered help you understand why your logic scope operates
the way it does.
Section 3 Reference teaches you how to perform specific tasks. See page 3–1 for
a complete list of tasks covered in that section.
The Appendices provide an options listing, an accessories listing, and other
useful information.
In the Getting Started and Reference sections, you will find various procedures
which contain steps of instructions for you to perform. To keep those instructions
clear and consistent, this manual uses the following conventions:
H Names of front-panel controls and menu labels appear in boldface print.
H Names also appear in the same case (initial capitals, all uppercase, etc.) in
the manual as is used on the logic scope front panel and menus. Front panel
names are all upper case letters, for example, GROUP MENU and
GROUP 1.
H Instruction steps are numbered. The number is omitted if there is only one
step.
H When steps require that you make a sequence of selections using front-panel
controls and menu buttons, an arrow ( ➞

Start Up
Before You Begin
Operation
Before you use the TLS 216 Logic Scope, ensure that it is properly installed and
powered on.
To ensure maximum accuracy for your most critical measurements, you should
know about signal path compensation.
Be sure you compensate your logic scope for the surrounding temperature. This
action, called Signal Path Compensation (SPC), ensures maximum possible
accuracy for your most critical measurements. See Doing a Signal Path
Compensation on page 3–53 for a description of use and operation of this
feature.
To properly install and power on the logic scope, do the following tasks.
Installation
1. Be sure you have the appropriate operating environment. Specifications for
temperature, relative humidity, altitude, vibrations, and emissions are
included in the manual TLS 216 Performance Verification and Specification
shipped with this logic scope.
2. Leave space for cooling. Do this task by verifying that the air intake and
exhaust holes on the sides of the cabinet (where the fan operates) are free of
any airflow obstructions. Leave at least 5.1 cm (2 inches) free on each side.
WARNING. To avoid electrical shock, be sure that the power cord is disconnected
before checking the fuse.
3. Check the fuse to be sure it is the proper type and rating (stated on rear
panel). You can use either of two fuses. (See Figure 1-1 for fuse location.)
Each fuse requires its own cap. (See Table 1–1.) The logic scope is shipped
with the UL approved fuse installed.
4. Check that you have the proper electrical connections. The logic scope
requires 90 to 250 VAC
require up to 300 W.

6. Remove the front cover by grasping its left and right edges and snapping it
off of the front subpanel. (When reinstalling, align and snap back on.)
1. Check that the rear-panel principal power switch is on. (See Figure 1-1.) The
principal power switch controls all AC power to the instrument.
2. If the logic scope is not powered on (the screen is blank), press the front-panel ON/STBY button to toggle it on. (See Figure 1-2.)
The ON/STBY button controls power to most of the instrument circuits.
Power continues to go to certain parts even when this switch is set to STBY.
Once the logic scope is installed, it is typical to leave the principal power
switch on and use the ON/STBY button as the power switch.

Check the self test results. The logic scope automatically performs power-up
tests each time it is turned on. It will display a status screen that states whether
or not it passed self test. (If the self test passed, the logic scope removes the
status display screen after a few seconds.)
If the self test fails, call your local Tektronix Service Center. Depending on the
type of failure, you may still be able to use the logic scope before it is serviced.
Press the ON/STBY switch to turn off the logic scope.

Setting Up for Examples
Perform the following tasks to connect input signals to the TLS 216 Logic
Scope, to reset it, and to become acquainted with its display screen. Once
completed, these tasks ready the logic scope for use in the examples that follow.
Perform the examples that follow this subsection to learn how to display and
measure waveforms with the logic scope.
Connect the Input Signals
Do the following steps to couple input signals to the logic scope for use in the
examples.
1. Remove all probes and signal inputs from the 16 input connectors along the
lower right of the front panel.
2. Connect a probe to each of the Channel 1 through Channel 4 inputs using
four of the probes supplied with the logic scope. (See Figure 1-3.)
3. Connect the input of the four probes to any four of the 16 probe calibration
outputs. (See Figure 1-3). Be sure to connect so the positive terminal of the
each probe (indicated by three ribs at the end of the probe tip) goes to the
positive (upper) terminal of the probe calibration output.

Do the following steps to reset the logic scope to a known factory default state
before doing the examples. (You can reset the logic scope anytime you begin a
new task and need to “start fresh” with known default settings.)
1. Press the save/recall SETUP button to display the Setup menu (Figure 1-4).

Because an accidental instrument reset could destroy a setup that took a long
time to create, the logic scope asks you to verify the Recall Factory Setup
selection. (See Figure 1-5.)

3. Press the button to the right of the OK Confirm Factory Init side menu
item.
NOTE. This manual uses the following notation to represent the sequence of
selections you made in steps 1, 2 and 3: Press save/recall SETUP ➞ Recall

Note that a clock icon appears on screen. The logic scope displays this icon
when performing operations that take longer than several seconds.
4. Press SET LEVEL TO 50% to be sure the logic scope triggers on the input
signal. (See Figure 1-6.)

Examine the Display Elements
Read the following information to become familiar with the logic scope display
before doing the examples.
Figure 1-7 shows the display that results from the instrument reset. Note the
following characteristics.
The logic scope always displays a single group (Group 1) which contains only
one channel (Channel 1) after a reset.
The trigger threshold bar shows that the logic scope triggered the waveform at a
threshold level near 50% of its amplitude (from step 4).
The trigger position indicator shows that the trigger position of the waveform is
located at the horizontal center of the graticule.
TLS 216 User Manual
1–9
Setting Up for Examples
The group reference indicator shows the vertical position of any channels that
Group 1 contains when the channels have no input signal. For the current group
display mode (Analog), this indicator points to the ground level for all channels
in the group when vertical offset is set to 0 V in the group menu; when vertical
offset is not set to 0 V, it points to the vertical offset level.
The trigger readout shows that the logic scope triggers using the edge of a signal
(rising or falling signal transitions that pass through the trigger threshold).
The time base readout shows that the main time base is set to a horizontal scale
of 500 ms/div.
The vertical readout indicates that Group 1 is displayed and that it includes
Channel 1 as the first and also the last channel in the group. The logic scope uses
this format for each group readout in the vertical readout: group number [last
channel:first channel] group volts/division setting.
