Acquisition circuitry in the TDS 794D is very susceptible to damage from
electrostatic discharge and from overdrive signals.
To prevent electrostatic damage to the TDS 794D, be sure to operate the
oscilloscope only in a static-controlled environment. Be sure to discharge to
ground any electrostatic charge that may be present on cables and probes before
attaching them to the oscilloscope.
To prevent damage from electrostatic discharge, install short-circuit terminations
on unused input connectors. Always use a wrist strap with internal impedance
(provided with your instrument) when handling your oscilloscope or making
connections.

Preface
Default Model
Model References
This manual documents the TDS 500D, TDS 600B, & TDS 700D Digitizing
Oscilloscopes. Take special note of the following conventions:
Some TDS models have two auxiliary channels called AUX 1 and AUX 2,
instead of CH 3 and CH 4. References to these channels default to CH 3 and
CH 4; if your oscilloscope is one of these models, read AUX 1 and AUX 2
respectively for all references to CH 3 and CH 4 in this manual.
The TDS 684B display screen appears as the default screen wherever a
display screen is illustrated in this manual.
This manual documents the TDS 500D, TDS 600B, & TDS 700D Digitizing
Oscilloscopes. Take note of the following conventions used when referencing
these oscilloscopes:
Conventions
The name “TDS 500D” is used when providing information common to the
TDS 520D, TDS 540D, and TDS 580D model oscilloscopes.
The name “TDS 600B” is used when providing information common to the
TDS 620B, TDS 644B, TDS 680B, and TDS 684B model oscilloscopes.
The name “TDS 700D” is used when providing information common to the
TDS 724D, TDS 754D, TDS 784D, and TDS 794D model oscilloscopes.
In this manual, 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:
In procedures, names of front panel controls and menu labels appear in
boldface print.

TDS 500D, TDS 600B, & TDS 700D User Manual
Preface
Names also appear in the same case (initial capitals or all uppercase) 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 and CH 1.
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 ( ➞ ) marks each transition between a
front panel button and a menu, or between menus. Also, whether a name is a
main menu or side menu item is clearly indicated: Press VERTICAL
MENU ➞ Coupling (main) ➞ DC (side) ➞ Bandwidth (main) ➞
250 MHz (side).
Using the convention just described results in instructions that are graphically
intuitive and simplifies procedures. For example, the instruction just given
replaces these five steps:
1. Press the front-panel button VERTICAL MENU.
2. Press the main-menu button Coupling.
3. Press the side-menu button DC.
4. Press the main-menu button Bandwidth.
5. Press the side-menu button 250 MHz.
Sometimes you may have to make a selection from a pop-up menu: Press
TRIGGER MENU➞Type (main) ➞ Edge (pop-up). In this example, you
repeatedly press the main menu button Type until Edge is highlighted in the
pop-up menu.

Start Up
Preparation
Before you use the TDS Oscilloscope, 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 and the proper use of the probe you choose
to use with your oscilloscope.
Signal Path Compensation
Recommended Probes
Probe Usage
Be sure you compensate your oscilloscope for the surrounding temperature. This
action, called Signal Path Compensation (SPC), ensures maximum possible
accuracy for your most critical measurements. See Signal Path Compensation on
page 3–156 for a description of and operating information on this feature.
The TDS 580D, TDS 680B, TDS 684B, TDS 784D, and TDS 794D oscilloscopes ship without probes. To take advantage of the higher bandwidth of these
oscilloscopes, order the P6245, P6217, or P6158 probes.
The remaining TDS 500D, TDS 600B, and TDS 700D oscilloscopes ship with
general-purpose probes. The probe model and quantities shipped are listed in
Standard Accessories on page A–4.
For a list of recommended optional-accessory probes for all oscilloscope models,
see Accessory Probes on page A–5.
Be sure you use the appropriate probe for the measurement. For instance, do not
use the P6245 Active Probe to measure signals greater than ±8 volts or with
more than ±10 volts of offset, since errors in signal measurement will result. (See
the User manual for the probe for more information.) Instead, use a passive
probe, such as P6139A passive probe, that allows higher voltage measurements.
The P6139A probe is for measurements up to ±500 volts.
Probes that require a 1 MW input, like the P6139A, will not work on the
TDS 794D.

CAUTION. Using the P6243 or P6245 Active Probe to measure signals greater
than ±40 volts may damage the probe. Using the P6158 Voltage Divider Probe to
measure signals greater than ±22 V
may damage the probe.
RMS
Input Coupling
Putting into Service
Installation
Be sure to choose the proper input coupling and impedance for the probe or other
cabling you use to couple signals to your oscilloscope. You should read InputImpedance Considerations on page 3–8 for information needed to ensure proper
coupling of your input signals.
To learn how to install, access the front panel, power on, do a self test, and
power off the oscilloscope, do the following procedures:
To properly install and power on the oscilloscope, do the following steps:
1. Be sure you have the appropriate operating environment. Specifications for
temperature, relative humidity, altitude, vibrations, and emissions are
included in the TDS 500D, TDS 600B, & TDS 700D Technical Reference(Performance Verification and Specifications) manual (Tektronix part
number 071-0135-xx).
2. Leave space for cooling. Do this by verifying that the air intake and exhaust
holes on the sides and bottom of the cabinet are free of any airflow obstructions. Leave at least 5.1 cm (2 inches) free on each side.
1–6
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).
You can use either of two fuses. Each fuse requires its own cap (see
Table
1–2). The oscilloscope is shipped with the UL approved fuse installed.
4. Check that you have the proper electrical connections. The oscilloscope
requires 100 to 240 VAC
require up to 300 W.

To remove the front cover, grasp the left and right edges and snap the cover off
of the front subpanel. (To reinstall the cover, align it to the front subpanel and
snap it back on.)
To power on the oscilloscope, do the following steps:
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 oscilloscope is not powered on (the screen is blank), push the
front-panel ON/STBY button to toggle it on (see Figure 1–2).

Figure 1–2: ON/STBY Button
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 oscilloscope is installed, it is typical to leave the principal power
switch on and use the ON/STBY button instead of the power switch.
The oscilloscope automatically performs power-up tests each time it is turned on.
It will come up with a display screen that states whether or not it passed the self
test. To determine the self-test results, check the screen. (If the self test passed,
the status display screen will be removed 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 oscilloscope before it is serviced.
To power off the oscilloscope, toggle the ON/STBY switch.
