Basic Controls

Figure 1: Front

Press to turn the TBS1052B-EDU on or off.

Press

default setup

to return the Oscilloscope to a known “default” state.

The TBS1052B-EDU has 2 channels. Pressing the channel number button will turn on/off the
channel. The vertical position button is located above the channel button. The volts per
division or scale knob is located below the channel button.

Trigger menu – Press the Level knob to place the trigger at the 50% mark of the signal.

Horizontal / Time – The time per division, or scale knob is at the bottom of the menu. The
horizontal position knob is at the top. You can press this knob to center the signal. Center is
based on the slope of the trigger menu.

Probe Compensation

The Tektronix probes must be compensated to produce an accurate waveform.

Turn on the TBS1052B-EDU. Wait 40 seconds for the scope to boot up.

Insert the Tektronix TPP0051 probe into channel 1. To connect the Tektronix probes, align
the BNC connector probe tabs vertically and insert into the channel input then twist the BNC
connector right until the tabs are horizontal. To remove the probe, align the tabs vertically
and pull the probe off the connector.

Connect the Probe tip to the PROBE COMP output as shown in

Figure 3

Press

Autoset

If the 5 volt, 1 KHz signal looks like either picture in

Figure 4,

continue to the next step.

Insert a probe compensation tool into the hole in the probe BNC connector and adjust it left
or right until the signal looks square. See

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

. This means you will see the DC component of the signal with the AC component.

By setting the

Coupling

softkey to

, 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

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

Press

Utility

button on the front panel.

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.

The firmware is listed and below the model number. See

Figure 6

If new firmware is available,

DO NOT INSTALL FIRMWARE YOURSELF

. Contact lab personnel

and we will update the Tektronix oscilloscope for you.

Figure 6

Cursors

To obtain manual measurements use the

Cursors

button near the

Multipurpose

wheel.

Press the

Cursor

button to access the cursors menu.

The default setting is for the cursors to be off. Press the

Type

softkey and use the

Multipurpose

wheel to select either

Amplitude

Time

. Then press the

Multipurpose

wheel

to select your choice.

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.

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

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

Off
