Conventions
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 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.

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 Appendix B: Specifications at the rear of this manual.
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. The digitizing
oscilloscope requires 90 to 132 V for 48 through 62 Hz, 100 to 132 V or 180
to 250 V for 48 through 440 Hz, and may require up to 240 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.

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.
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).
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.

Before You Begin
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.
Signal Path Compensation (SPC) lets you compensate your oscilloscope for the
current ambient temperature. SPC helps ensure maximum possible accuracy for
your most critical measurements. See Signal Path Compensation on page 3–113
for a description of and operating information on this key feature.
