for this product.
Avoid Electric Overload. To avoid electric shock or fire hazard, do not apply a
voltage to a terminal that is outside the range specified for that terminal.
Avoid Overvoltage. To avoid electric shock or fire hazard, do not apply potential
to any terminal, including the common terminal, that varies from ground by
more than the maximum rating for that terminal.
Avoid Electric Shock. To avoid injury or loss of life, do not connect or disconnect
probes or test leads while they are connected to a voltage source.
Ground the Product. This product is grounded through the grounding conductor
of the power cord. To avoid electric shock, the grounding conductor must be
connected to earth ground. Before making connections to the input or output
terminals of the product, ensure that the product is properly grounded.

Conventions
In the Getting Started and Reference chapters, 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 oscilloscope front panel and menus. Front panel
names are all upper case letters, for example, VERTICAL MENU, CH 1,
and SETUP.
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
Operation
Before you use the digitizing oscilloscope, ensure that it is properly installed and
powered on.
To properly install and power on the digitizing oscilloscope, do the
following steps:
Installation
1. Be sure you have the appropriate operating environment. Specifications for
temperature, relative humidity, altitude, vibrations, and emissions are
included in performance verification and specification manuals (Tektronix
part numbers 070-9705-xx and 070-9706-xx).
2. Leave space for cooling. Do this 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 2 inches (5.1 cm) 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 (see Figure 1-1 for
the fuse location). You can use either of two fuses (see Table 1–1 for the
fuse data).
4. Check that you have the proper electrical connections:
H For TDS 400A serial number below B080000: 90 to 132 V for 48 Hz
through 62 Hz, 100 to 132 V or 180 to 250 V for 48 through 440 Hz,
and may require up to 240 W.
H For TDS 400A serial number B080000 - Up: 100 to 240 V ±10%,
50/60 Hz nominal, or 115 V ±10% for 400 Hz, and may require up to
240 W.
H For TDS 510A all serial numbers: 90 to 250 V for 45 Hz to 440 Hz, and
may require up to 300 W.
5. Connect the proper power cord from the rear-panel power connector (see
Figure 1-1 for the connector location) to the power system.

ON/STBY Button
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 for the
location of the switch ). The principal power switch controls all AC power to
the instrument.
NOTE. TDS400A instruments with serial number B080000 or above do not have
a principal power switch.
2. If the oscilloscope is not powered on (the screen is blank), push the
front-panel ON/STBY button to toggle it on (Figure 1-2).
Once the digitizing oscilloscope is installed, you can leave the principal
power switch on (TDS400A instruments below B080000 and all TDS510A
instruments) and use the ON/STBY button .
Self Test
Power Off
Figure 1-2: ON/STBY Button
The digitizing oscilloscope automatically performs power-on tests each time it is
turned on. It comes up with a display screen that states whether or not it passed
self test. If the self test does not detect any problems, the status display screen
disappears a few seconds after the self test is complete.
Check the self test results.
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 oscilloscope before it is serviced.
Press the ON/STBY switch to turn off the oscilloscope.

This section quickly acquaints you with some of the fundamental operations
required to use your digitizing oscilloscope to take measurements. Start this
tutorial by doing Setting Up for the Examples.
Setting Up for the Examples
Perform the following tasks to connect input signals to the digitizing oscilloscope, to reset it, and to become acquainted with its display screen. Once
completed, these tasks ready the digitizing oscilloscope for use in the examples
that follow.
Connect the Input Signal
Remove all probes and signal inputs from the input BNC connectors along the
lower right of the front panel. Then, using one of the probes supplied with the
digitizing oscilloscope, connect from the CH 1 connector of the digitizing
oscilloscope to the Probe Compensation connector (Figure 2-1).
