Basics
This section will help you become familiar with adjusting the vertical and horizontal controls, taking
continuous or a single measurements and how to adjust the trigger.
Autoset and Default setup
Normally when you are measuring a signal you can press the Autoset button and the oscilloscope will
automatically adjust the vertical and horizontal scale setting to an appropriate setting and display the
peak to peak voltage, mean, period and frequency values. You can adjust this setting following the
instructions below. If you ever get the oscilloscope into a setting where you can’t see the signal your
measuring, you can press the Default Setup button to restore the oscilloscope to a predefined state.
Note: the default setup button does not affect the save / recall settings.
Vertical Menu
The vertical menu allows you to measure the voltage of an alternating current or signal. The screen has
8 blocks going from the bottom of the screen to the top. The value of each square is set by the large
control knob (Scale knob) below the channel number button. You will normally adjust the vertical Scale
knob where you can see the largest signal on the screen without having the signal go off the screen.
The position knob above the channel number in the vertical menu moves the entire signal up or down.
By pressing the channel number (1 or 2) button, you can bring up the Coupling softkey. This will
normally be set to DC. This means you will see the DC component of the signal with the AC component.
By setting the Coupling softkey to AC, you will remove any DC voltage from the signal you are
measuring.
The probes that come with the TBS1052B-EDU are x10 probes. This means a 10 volt peak to peak signal
will come into the oscilloscope at 1 volt peak to peak. Because we know the signal is actually 10 times
larger, the oscilloscope is defaulted to show the signal it receives as 10 times the actual input. If you use
an oscilloscope probe that is not a times 10 probe, you will need to press the channel number (1 or 2)
button then the Probe softkey. This will bring up the Attenuation softkey. Press the Attenuation softkey
and use the Multipurpose wheel to select the correct probe attenuation.
Horizontal Menu
The horizontal menu adjusts the time parameters of the oscilloscope. There are 10 blocks going from
the left side of the screen to the right side of the screen. The large Scale knob in the Horizontal menu
will adjust each square to a different time scale, from 50 seconds to 5 nanoseconds. The position knob in
the horizontal menu moves the entire signal left and right on the screen. Pushing the Position knob will
center the signal to the middle of the screen. The Acquire button will allow you to take continuous
samples or take an average of different sample sizes of the signal.
Trigger Menu
The signal on the screen of the oscilloscope is drawn from left to right many, many times a second. In
order for the oscilloscope to draw a repeating signal that is steady (doesn’t drift or freeze), it needs to

6
define a starting point on when to start drawing the signal on the screen. The Level knob in the trigger
menu sets a horizontal line on the oscilloscope where any time the signal voltage goes above that line,
the oscilloscope will start drawing a signal on the screen.
Run / Stop and Single Buttons
Normally you will keep the oscilloscope in the Run mode. The Run / Stop button will light up Green to
indicate it is in the run mode. Pressing the Run / Stop button turns the button red and freezes the
screen. If you wish to take one single measurement, simply press the Single button. Press the Run /
Stop button again to turn the run mode back on.
Firmware
Firmware in most test equipment controls the entire device, much like the operating system of a
computer. Firmware is programmed into permanent memory of the device, like an EEPROM. Many
times test equipment manufacturers will update their firmware to fix bug or add new features to a
product. It is important to know the firmware of all your test equipment and keep track of new versions
of firmware for your test equipment. The current version of firmware for the Tektronix TBS1052B-EDU
oscilloscope is v4.06 as of 01/10/2017.
Checking the firmware
1. Press Utility button on the front panel.
2. Press the –more- page 1 of 3 softkey twice to get to page 3 of 3. Then press System Status.
Press Misc. to see the firmware, serial number, communication addresses and to see the
status of different tests the scope has undergone.
3. The firmware is listed and below the model number. See Figure 6.
4. If new firmware is available, DO NOT INSTALL FIRMWARE YOURSELF. Contact lab personnel
and we will update the Tektronix oscilloscope for you.

Cursors
To obtain manual measurements use the Cursors button near the Multipurpose wheel.
1. Press the Cursor button to access the cursors menu.
2. The default setting is for the cursors to be off. Press the Type softkey and use the
Multipurpose wheel to select either Amplitude or Time. Then press the Multipurpose wheel
to select your choice.
3. Selecting Amplitude will display new softkeys on the menu. Ensure the Source softkey is on
the channel you wish to measure. Press Cursor 1 and use the Multipurpose wheel to move
the cursor to the top of the signal your interested in. Press Cursor 2 and use the
Multipurpose wheel to move the cursor to the bottom of the signal your interested in. The
middle softkey will show you the difference in Amplitude between the two cursors.
4. Selecting Time will display new softkeys on the menu. Ensure the Source softkey is on the
channel you wish to measure. Press Cursor 1 and use the Multipurpose wheel to move the
cursor to the start of the signal your interested in. Press Cursor 2 and use the Multipurpose
wheel to move the cursor to the stopping point of the signal your interested in. The middle
softkey will show you the difference in Time between the two cursors. See Figure 7.
5. Pressing the Menu On/Off button below the softkeys will hide the menu but leave the
cursors on the screen. To remove the cursors, set the top softkey Type to Off.
