Quick Tutorial
To Generate a Sine Waveform
The following quick tutorial describes how to generate a continuous sine waveform using Tektronix AFG3000 Series Arbitrary/Function Generators. Follow these steps to learn the basics of the arbitrary/function generator.
1. Connect the power cord, and then
push the front-panel power on/off
switch to turn on the arbitrary/function
generator.

5. Use the oscilloscope auto-scaling
function to display the sine waveform
on the screen.
If the instrument outputs a default sine
waveform, you can manually set the
oscilloscope as follows:
■
0.5 µs/div
■
200 mV/div
6. To change the frequency, push the
front-panel Frequency/Period shortcut button.

For example, if you enter a value "2"
using the keypad, the bezel menus will
automatically change to Units.
After entering the frequency value, push
the Units bezel button or the front-panel
Enter button to complete the entry.
You can change the Amplitude, Phase,
and Offset values in the same way.
9. You can also change the frequency
value using the general purpose knob
and the arrow keys.
To increase the value, turn the knob
clockwise.

Protect Your Instrument from Misuse
Check Input and Output Connectors
1. The instrument has both input and
output connectors on the front panel.
When connecting a cable, be sure to
distinguish the input connector from the
output connectors.
Input
Output
Do not mistake Output connectors for Input.
The arbitrary/function generator input and output connectors are floating inputs/outputs.
WARNING. To prevent electrical shocks, do not apply voltages in excess of 42 Vpk to any BNC connector ground or to the
chassis ground.
CAUTION. Do not short output pins or apply external voltages to Output connectors. The instrument may be damaged.
CAUTION. Do not apply excessive inputs over +5 V to Trigger Input connector. The instrument may be damaged.
Use Fuse Adapter
The instrument will be damaged if a large DC or AC voltage is applied to the output or input connectors. To protect the
output circuits, a fuse adapter is provided as an optional accessory. When the instrument is used by students or other inexperienced users, always attach the fuse adapter to the output connectors to avoid damage.
Tektronix part numbers for the fuse
adapter are as follows:

013-0345-00: Adapter

AFG3000 Series Quick Start User Manual

Getting Started
Floating Ground
Since the common (input and output channel common) of the arbitrary/function generator is electrically isolated from the
chassis ground (the instrument chassis and ground line of the AC connector), you can make a floating connection between
the instrument and other equipment.
All the signal output connectors are connected to the common ground, and the remote interface connector is connected to
the chassis ground.
CAUTION. When you make a floating connection, review the following precautions:
The maximum rated voltage between the chassis ground and common ground is 42 Vp-p (DC + peak AC). When the potential voltage between the chassis ground and common ground goes over 42 Vp-p, the internal protective circuit will be activated to protect the circuits. However, higher voltage may cause the internal circuits in the instrument to be damaged.
When a potential voltage exists between the chassis ground and common ground, a short circuit from output to ground
causes the instrument internal fuse to open and the output is stopped. If the fuse opens, you need to contact your local
Tektronix Service Support.
When a potential voltage exists between the common ground and chassis ground, short-circuiting between them may lead
to excessive current flow and the internal or external circuits may be damaged.

Generate a Burst Waveform
The arbitrary/function generator can output a burst using standard waveforms, such as sine, square, ramp, and pulse, or
arbitrary waveforms. The instrument allows you to use the following two types of burst modes:
Triggered Burst Mode. A specified number (burst count) of waveform cycles are output when the instrument receives
a trigger input from the internal trigger source, an external trigger source, a remote command, or the Manual Trigger
button.
Gated Burst Mode. The instrument outputs a continuous waveform either when an effective gate signal is applied externally, when the Manual Trigger button is depressed, when a remote command is applied, or during 50% of the selected
internal trigger interval.

Application Examples
Application Examples
This section contains a series of application examples. These simplified examples highlight the features of the arbitrary/function generator and give you ideas for using it to solve your own test problems.
Lissajous Patterns
Use the AFG3000 series dual-channel model to create a Lissajous pattern and observe the waveforms with an oscilloscope.
1. Connect the CH1 and CH2 Outputs of
the dual-channel arbitrary/function
generator and the CH1 and CH2 Inputs
of an oscilloscope with BNC cables.
Set the waveform parameters as follows:
■
Sine (Continuos)
■
Amplitude: 1 V
■
CH1 Frequency: 400 kHz
■
CH2 Frequency: 500 kHz
1
2. Set the oscilloscope display format to
XY. Adjust the amplitude so that the
waveform is shown in the graticule.
A Lissajous pattern is displayed.
2
3. Use the general purpose knob on the
arbitrary/function generator to change
the phase of CH1 or CH2. Observe
that the Lissajous pattern changes
shape.

Application Examples
Measurement of Filter Characteristics
Use the arbitrary/function generator sweep function to observe the frequency characteristics of 50 Ω filter.
1. Connect the CH1 output of the arbitrary/function generator and an oscilloscope CH1 input with a BNC cable.
Oscilloscope
AFG3000 series
2. Connect the Trigger Output of the arbitrary/function generator and the external trigger input connector of an
oscilloscope.
Set the oscilloscope input impedance to
50 Ω.

3. Select Sweep from Run Mode of the
arbitrary/function generator and set the
start frequency, stop frequency, and
sweep time so that the waveform is
shown in the graticule.
You can measure the frequency characteristics of the filter by sweep time
and the oscilloscope time base.

Application Examples
Motor Speed Control by Pulse-Width Modulation
Pulse-width modulation is used for controlling the speed of a DC motor or the luminance of an LED (Light Emitting Diode).
Use the arbitrary/function generator PWM function to control the DC motor speed.
1. Connect the arbitrary/function generator output and a DUT using a
BNC-to-alligator clip adapter.
DUT (example: Motor)
AFG3000 Series
1
2. Select Pulse as an output waveform
and then select PWM as a modulation
type.
2
Set the frequency to approximately
100 kHz.
3. Connect the output to an oscilloscope.
Confirm that a pulse-width modulation
waveform is displayed on the oscilloscope screen.
Select Pulse Duty and change the duty
rate. Observe that the motor speed
changes if you change the duty rate.

Application Examples
Carrier Null (Frequency Modulation)
Use the arbitrary/function generator and spectrum analyzer to observe a carrier waveform of frequency modulation.
1. Select Sine as an output waveform
and then select FM as the modulation
type.
1
2. Set the waveform parameters as follows:
■
Carrier frequency: 1 MHz
■
Modulation frequency: 2 kHz
3. Change Deviation.
Set the deviation to 4.8096 kHz. It makes
the carrier waveform null. Confirm that
the carrier null can be observed on the
spectrum analyzer.

Specifications
This section contains the specifications for the AFG3000 Series Arbitrary/Function Generators. All specifications are
guaranteed unless noted as “typical”. Typical specifications are provided for your convenience but are not guaranteed.
Specifications that are marked with ✔ symbol are checked in Performance Verification section of the service manual, an
optional accessory.
All specifications apply to the arbitrary/function generator unless noted otherwise. These specifications are valid under
three conditions:
■
The arbitrary/function generator must have been calibrated/adjusted at an ambient temperature between +20 ° C and
+30 ° C.
■
The arbitrary/function generator must have been operating continuously for 20 minutes within the specified operating
temperature range.
■
The instrument must be in an environment with temperature, altitude, and humidity with the operating limits described
in these specifications.
