Main Feature Description
Chapter 4 Main Feature Description
This chapter provides some general information that you need to learn before using an
oscilloscope. It cont ains:
1. Oscilloscope setup
2. Trigger
3. Data acquisition
4. Wavefor m sc al ing and positioning
5. Waveform measurement
4.1 Oscilloscope Setup
While operating the oscilloscope, you may often use three features: Autoset, saving a setup and
recalling a setup. Hereinaf ter they are introduced one by one.
Autoset: This function can be used to adjust the horizontal and vertical scales of the oscilloscope
automatically and set the trigger coupling, type, position, slope, level and mode, etc., to acquire a
stable waveform display .
Saving a Setup: By default, the oscilloscope will save the setup each time before being closed,
and automatically recall the setup once being turned on. (Note: If you modify the setup, please
wait for more than 5 seconds before turning off the oscilloscope to ensure the proper
storage of new settings.) You can save 10 settings permanently in the oscilloscope and reset
them as necessary.
Recalling a Setup: The oscilloscope can recall any of your saved setups or the default factory
setup.
Default Setup: The oscilloscope is preset for normal operations when it is shipped from the
factory. This is the default setup. You may recall this setup at any time for your requirements. To
view the default settings, refer to
Section 5.6.3.
4.2 Trigger
The trigger determines when the oscilloscope begins to acquire data and display a waveform.
Once a trigger is properly set up, the oscilloscope can convert unstable displays or blank screens
to meaningful waveforms. Here introduce some bas i c concepts about trigger.
Trigger Source: Th e trigg er can be ge nerated w ith multi ple sources . The mos t common o ne is th e
input channel (alternative between CH1 and CH2). Whether the input signal is displayed or not, it
can trigger normal operations. Also the trigger source can be any signal connected to an external

Main Feature Description
Trigger slope can be rising or falling
Rising Edge
Falling Edge
Trigger level can be
adjusted vertically
trigger channel or the AC power line (only for Edge triggers). The source with the AC power line
shows the frequency relationship between the signal and t he AC co m mercial power.
Trigger Type: The oscilloscope has six types of triggers: Edge, Video, Pulse Width, Slope,
Overtime and Swap.
Edge Trigger uses the analog or digital test circuits for triggering. It happens when the
input trigger source crosses a specified level in a specified direction.
Video T r igger performs a fie ld or l ine trigger through standard video signals.
Pulse Width Trigger can trigger normal or abnorma l pulses t hat meet trigger conditions.
Slope Trigger uses the rise and fall times on the edge of signal for t r iggering.
Overtime Trigger happens after the edge of signal reaches the set time.
Swap Trigger, as a feature of analog oscilloscopes, gives stable displays of signals at
two different frequencies. Mainly it uses a specific frequency to switch between two
analog channels CH1 and CH2 so that the channels will generate swap trigger signals
through the trigger cir cuitry.
Trigger Mode: You can select the Auto or Normal mode to define how the oscilloscope acquires
data when it does not detect a trigger condition. Auto Mode performs the acquisition freely in
absence of valid trigger. It allows the generation of untriggered waveforms with the time base set
to 80ms/div or slower. Normal Mode updates the displayed waveforms only when the
oscilloscope detects a valid trigger condition. Before t his update, the oscilloscope still displays the
old waveforms. This mode shall be used when you want to only view the effectively triggered
waveforms. In this mode, the oscilloscope displays waveforms only after the first trigger. To
perform a single seque nce acquisition, push the SINGLE SEQ button.
Trigger Coupling: Trigger Coupling determines which part of the signal will be delivered to the
trigger circuit. This can help to obtain a stable display of the waveform. To use trigger coupling,
push the TRIG MENU button, select an Edge or Puls e trigger, and then select a Coupling opti on.
Trigger Position: The horizontal position control establishes the time betw een the trigger position
and the screen center.
Slope and Level: The Slope and Level controls help to define the trigger. The Slope option
determines whether the trigger point is on the rising or falling edge of a signal. To perform t he
trigger slope control, press the TRIG MENU button, select an Edge trigger, and use the Slope
button to select rising or falling. The TRIGGER LEVEL knob controls the trigger point i s on whi ch
position of the edge.
DSO-1062D Digital Oscilloscope User Manual 10
Main Feature Description
4.3 Data A cquisition
When you acquire an analog signal, the oscilloscope will convert it into a digital one. There are
two kinds of acquisition: Real-time acquis ition and Equival ent acquis ition. The real-ti me acquisiti on
has three modes: Normal, Peak Detect, and Average. The acquisition rate is affected by the
setting of time base.
Normal: In this acquisition mode, the oscilloscope samples the signal in evenly spac ed intervals to
establish the waveform. This mode accurately represents signals in most time. However, it does
not acquire rapid variations in the analog signal that may occur between two samples, which can
result in aliasing and may cause narrow pulses to be missed. In such cases, you should use the
Peak Detect mode to acquire data.
Peak Detect: In thi s ac quisitio n mod e, t he osci llosco pe gets the maximum and minimum values of
the input signal over each sample interval and uses these values to display the waveform. In this
way, the oscilloscope can acquire and display those narrow pulses that may have otherwise been
missed in Normal mode. However, nois e w il l appear to be higher in this mode.
Average: In this acquisition mode, the oscilloscope acquires several waveforms, averages them,
and displays the resultin g w aveform. You can use this mode to reduce random noise.
Equivalent Acquisition: This kind of acquisition can be utilized for periodi c signals. In case the
acquisition rate is too low when using the real-time acquisition, the oscilloscope will use a fixed
rate to acquire data with a stationary tiny delay after each acquisition of a frame of data. After
repeating this acquisition for N times, the oscilloscope will arrange the acquired N frames of data
by time to make up a new frame of data. Then the waveform can be recovered. The number of
times N is related to the equivalent acquis ition rate.
Time Base: The oscilloscope digitizes waveforms by acquiring the value of an input signal at
discrete points. The time base helps to control how often the values are digitized. Use the
SEC/DIV knob to adjust the time base to a hor iz ontal scale that suits your pur pose.
4.4 Waveform Scaling and Positioning
The display of waveforms on the screen can be changed by adjusting their scale and position.
Once the scale changes, the waveform display w ill increase or decrease i n siz e. Once the position
changes, the waveform will move up, dow n, r ight, or left.
The channel reference indicator (located on the left of the graticule) identifies each waveform on
the screen. It points to the ground lev el o f the waveform record.
Vertical Scale and Posi t ion: The vertical posit ion of a waveform can be changed by moving it up
and down on the screen. To compare data, you may align a waveform over another. When yo u
push the VOLTS/DIV button to change the vertical scale of a waveform, the waveform display will
contract or expand vertica lly t o t he gr ound level.
Horizontal Scale and Position: Pretrigger Information
DSO-1062D Digital Oscilloscope User Manual 11
Main Feature Description
You can adjust the HORIZONTAL POSITION control to view waveform data before the trigger,
after the trigger, or some of eac h. When you change the horiz ontal pos ition of a wav eform, you ar e
actually changing the time bet ween the trigger position and the screen center.
For example, if you want to find out the cause of a glitch in your test circuit, you should trigger on
the glitch and make the pretrigger period long enough to capture data before the glitch. Then you
can analyze the pretrigger data and perhaps find the cause. You are allowed to change the
horizontal scale of all the waveforms by turning the SEC/DIV knob. For exam ple, you may want to
see just one cycle of a waveform to measure the overshoot on its rising edge. The osci lloscope
shows the horizontal scale as time per division in the scale readout. Since all active waveforms
use the same time base, the osc il loscope only displays one value for all the active channels.
4.5 Waveform Measurement
The oscilloscope displays graphs of voltage versus time and can help to measure the displayed
waveform. There are several ways to take measurements, using the graticule, the cursors or
performing an automatic me asurement.
Graticule: This method allows you to make a quick, visual estimate and take a simple
measurement through the graticule divisions and the sc al e fa c t or .
For example, you can take simple measurements by counting the major and minor graticule
divisions involved and multiplying by the scale factor. If you counted 6 major vertical graticule
divisions between the minimum and maximum values of a waveform and knew you had a scale
factor of 50mV/division, you could easily calculate your peak-to-peak voltage as fo llows:
6 divisions x 50mV/division = 300mV.
Cursor: This method allows you to take measure m ent s by moving the cursors. Cursors always
appear in pairs and the displayed r eadouts are just their measur ed values. There are two kinds of
cursors: Amplitude Curs or and Time Cursor. The am plitude cursor appear as a horizontal broken
line, measuring the vert ical parameters. The time cur s or appear as a vertical broken line,
measuring the horizonta l parameters.
When using cursors, please make sure to set the Source to the waveform that you want to
measure on the screen. To use cursors, push the CURSOR button.

Automatic Measurement: The oscilloscope performs all the calculations automatical ly in t his
mode. As t his measurement uses the waveform record points, it is more precise than the graticule
and cursor measurements. Automatic measurem ents show the measure me nt r esults by readouts
which are periodically upd at ed with the new data acquired by the oscilloscope

The XY format is used to analyze phase differences, such as those represented by Lissajous
patterns. The format plots the voltage on CH1 against the voltage on CH2, where CH1 is the
horizontal axis and CH2 is the vertical axis. The oscilloscope uses the untriggered Normal
acquisition mode and displays data as dots. The sampling rate is fixed at 1 MS/s.
The oscilloscope can acquire waveforms in YT format at any sam pling rate. You may view the
same waveform in XY format. To perform this operation, stop the acquisition and change the
display format to XY.

5.3.1 Math FFT
This chapter elaborates how to use the Mat h FFT (Fast Fourier Transform). You can use the Math
FFT mode to convert a time-domain (YT) signal into its frequency components (spectrum), and to
observe the following t ypes of signals:
Analyze harmonics in power cords;
Measure harmonic content and distort i on i n s ystems;
Characterize noise in DC power sup pl ies;
Test impulse response of filters and systems;
Analyze vibration.
To use the Math FFT mode, perfor m the following tasks:
Set the source (time-domain) wav ef or m;
Display the FFT spectrum;
Choose a type of FFT window;
Adjust the sample rate to display the fu ndamental frequency and harmonics without aliasing;
Use zoom controls to magnify t he spect r um;
Use cursors to measure the spectr um.
5.3.1.1 Setting Time-domain Waveform
It is necessary to set the time-domain (YT) waveform before us ing the FFT mode. Fol low the step s
below.
1. Push the AUTOSET but ton to display a Y T waveform.
2. Turn the VERTICAL POSITION knob to vertically move the YT waveform to the center (zero
division) so as to ensure the FFT will display a tr ue D C value.
3. Turn the HORIZONTAL POSITION knob to position the part of the YT waveform to be
analyzed in the center eight divisions of the screen. The oscilloscope uses the 2048 center
points of the time-dom ain waveform to calculate the FFT spectrum.
4. Turn the VOLTS/DIV knob to ensure the entire waveform remains on the screen. If the entire
waveform is invisible, the oscilloscope may display wrong FFT results by adding
high-frequency components.
5. Turn the SE C/DIV knob to provide the resolution you need in the FFT spectrum.
6. If possible, set the oscillos cope t o display multiple signal cycles.
If you turn the SEC/DIV kn ob to se lect a faster set ting ( fewer cycl es), the FF T s pectru m will display
a larger frequency range and r educe the possibility of FFT aliasing.
To set the FFT display, follow t he st eps below.
1. Push the MATH MENU bu t ton;

2. Set the Operation option to FFT;
3. Select the Math FFT S ource channel.
In many situations, the oscilloscope can also generate a useful FFT spectrum despite the YT
waveform not being triggered. This is especially true if the signal is periodic or random (such as
noise).
Note: You sh ould t r i gg er and position transient or burst waveforms as close as possible to
the screen center.
Nyquist Frequency
The highest frequency that any real-time digital oscilloscope can measure without errors is half of
the sample rate, which is called the Nyquist frequency. Frequency information beyond t he Nyquist
frequency is undersampled which brings about the FFT aliasing. The math function can convert
the center 2048 points of the time-domain waveform to an FFT spectrum. The resulting FFT
spectrum contains 1024 points from DC (0Hz) to the Nyquist frequency. Usually, the screen
compresses the FFT spectrum horizontally to 250 points, but you can use the FFT Zoom fu n ct io n
to expand the FFT spectru m so that y ou can c lear ly v iew t he freq uency com ponent s at e ach o f the
1024 data points in the FFT spectrum.
Note: The oscilloscope’s vertical response is a little bit larger than its bandwidth (60MHz;
or 20MHz when the Bandwidth Limit option is set to Limited). Therefore, the FFT spectrum
can display valid frequency information above the oscilloscope bandwidth. However, the
amplitude infor mation near or ab ove the bandwidth will not be accurate.

5.3.1.3 Selecting FFT Window
Using windows can eliminate the spectral leakage in the FFT spectrum. The FFT algorithm
assumes that the YT waveform repeats all the time. When the number of cycles is integral (1, 2,
3 ...), the YT waveform starts and ends at the same amplitude and there are no discontinuities in
the signal shape.
If the number of cycles is nonintegral, t he YT waveform st art s and ends at di ffer ent amplitud es and
transitions between the start and end points will cause discontinuities in the signal that introduces
high-frequency transients.

Applying a window to the YT waveform changes the waveform so that the start and stop values

The Math FFT function has three FFT Window options. There is a trade-off between frequency
resolution and amplitude accuracy for each type of window. You shall determine which one to
choose according to the object you want to measure and the sour ce signal characteristics.

5.3.1.4 FFT Aliasing
Problems occur when the t ime-domain waveform acquire d by the oscilloscope cont ai ns frequency
components higher than the Nyquist frequency. The frequency components above the Nyquist
frequency will be undersampled and displayed as lower frequency components that ‘fold back’
from the Nyquist frequency. These erroneous components are ca lled aliases.
5.3.1.5 Eliminating Aliases
To eliminate aliases, use the following methods.
Turn the SEC/DIV knob t o set a faster sample rate. Bec aus e t he Nyquist frequency increases
as you increase the sample rate, the aliased frequency components will be displayed cor r ec t.
If too many frequency components appear on the screen, you may use the FFT Zoom option
to magnify the FFT spect rum.
If there is no need to observe the frequency components above 20MHz, set the Bandwidth
Limit option to Limited.
Filter the signal input from outside and limit the bandwidth of the source waveform to lower
than the Nyquist frequency.
Identify and ignore the aliased frequencies.
Use zoom controls and cursors to magnify and measure the F FT spectrum.
5.3.1.6 Magnif ying and Positioning FFT Spectrum
You may scale the FFT spectrum and use cursors to measure it through the FFT Zoom option
which enables the horizontal magnification. To vertically magnify the spectrum, use the vertical
controls.
Horizont a l Zoom and Posit i on
You can use the FFT Zoom option to magnify the FFT spectrum horizontally without changing the
sample rate. The available zoom factors are X1(default), X2, X5 and X10. When the zoom factor is
set to X1 and the waveform is located at the center graticule, the left graticule line is at 0Hz and
the right is at the Nyquist freque nc y.
You magnifies the FFT spectrum to the center graticule line when you change the zoom factor.
That is, the axis for horizontal magnification is the center graticule line. Turn the Horizontal
Position knob clockwise to mov e t he FFT spectrum to the right. Push the SET TO ZERO button to
position the center spectr um at t he center of the graticule.
Ver t ical Zoom and Posi t ion
When the FFT spectrum is being displayed, the channel vertical knobs become the zoom and
position controls corresponding to their respective channels. The VOLTS/DIV knob provides the
following zoom factors: X1(default), X2, X5 and X10. The FFT spectrum is magnifi ed ve rtic ally to

represent what shown in the figure below, you can get the value of the phase difference angle by
the formula: θ=±arcsin(A/B) or ±arcsin(C/D).
If the principal axes of the ellipse are in the first and third quadrants, the phase difference angle
should be in the first and fourth quadrants, i.e. within (0~π/2) or (3π/2~2π). If the principal axes of
the ellipse are in the second and fourth quadrants, the phase difference angle should be in the
second and third quadrants, i.e. within (π/2~π) or (π-3π/2). See the figure below for better
understanding.

3) Che ck the input signal to verify it has been c onnected to the probe correct ly;
4) Affirm that all measured c i r cuits have signals to output ;
5) Turn up the magnitude for DC signals with large magnitude;
6) In addition, you may press the Auto Measure button to perform an automatic detection of
signals at first.
Contact our Technical Sup port department in time if t her e is still no display of wavefor ms.
3. If the waveform of the input signal is distorted seriously, follow these steps:
1) Che ck the probe to assure its proper connection to the channe l B NC;
2) Che ck the probe to assure its good connection to the measured object;
3) Check the probe to verify it has been well calibrated. Otherwise, refer to the content about
calibration described in thi s ma nual.
4. If the waveform is rolling continuously on the screen but can not be triggered, follow
these steps :
1) Che ck the trigger source to make sure it consistent with the input chan nel;
2) Check the trigger level to assure its correct adjustment. You may push the TRIGGER LEVEL
knob or press the SET TO 50% button t o reset the trigger level back to the cent er of the signal;
3) Check the trigger mode to confirm it is a right choice for the input signal. The default trigger
mode is edge trigger. However, it is not suitable for all kinds of input signals.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free S oftware Foundation, I nc. ,
51 Franklin St r eet , Fi fth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and di st r ibute verbatim copies of this license document, but
changing it is not allowed.
Preamble
The licenses for most s oftware are designed to take away your freedom to share and change it.
By contrast, the GNU Gen er al P ublic License is intended to guarantee your freedom to sh ar e and
change free software--to make sure the so ftware is free for all its users. This General Public
License applies to most of t he Fr ee Software Found at ion's software and to an y other program
whose authors commit tousing it. (Some other Free Softw ar e Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to your programs, too.
When we speak of free so ftware, we are referring t o freedom, notprice. Our General Public
Licenses are designed to ma ke sur e t hat you have the freedom to distribute copies of free
software (and charge for this service if you wish), t hat you receive source code or can get it if you
want it, that you can change t he software or use pieces o f it in new free programs; and that you
know you can do these things.
To protect your rights, we need to ma ke r est r ictions that forbid anyone to deny you these rights
or to ask you to surrender t he rights. These rest r ictions translate to cert ain responsibilities for you
if you distribute copies of the software, or if you mod ify it.
For example, if you distr ibute copies of such a program, whether gratis or for a fee, you must
give the recipients a ll the rights that you have. You must make sure that they, too, receiv e or can
get the source code. And you must show them these terms so they know t heir rights.
We protect your r ights with two steps: ( 1) copyright the software, and (2) offer you t his lic ense
which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to ma k e cer tain that everyone understands
that there is no warranty for this free software. If the software is modified by someon e el se and
DSO-1062D Digital Oscilloscope User Manual 73
Harmful and Poisonous Substances or Elements
passed on, we want its recipients to know that what they have is not the origin al, so that any
problems introduced by ot her s w il l not r eflect on the original author s ' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the
danger that redistributors of a free program will individu ally obt ain p ate nt licens es, in effect making
the program proprietary. To prevent t his, we have made it clear that any patent must be licensed
for everyone's free use or not licensed at all.
The precise terms and c onditions for copying, distr ibut io n and modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License app li es to any program or other work which contains a notice placed by the
copyright holder saying it may be distri buted under the terms of this Genera l Publ ic Licens e. The
"Program", below, r efers to any such progr am or w ork, and a "w or k based on the Progra m" means
either the Program or any derivat ive w ork under cop y right law : that is to say, a work containing the
Program or a portion of it, either verbatim or with modific at ions and/or translated into another
language. (Hereinafter, translation is i ncluded without limitat i on i n the term "modification". )
Each licensee is addresse d as " you".
Activities other than copy i ng, dist r i but ion and modification are not covered by this License; t hey
are outside its scope. The act of
running the Program is not restricted, and the output fro m the Program is covered only if its
contents constitut e a w ork based on the Progra m (in dependent of having been made by running
the Program). Whether t hat is true depends on what t he Pr ogr am does.
1. You may c opy and distribute verbatim co pies of the Program's source code as you receive it,
in any medium, provided that you conspicuously and appropriately publish on each copy an
appropriate copyrig ht noti ce and disc lai mer of warra nty ; keep int act all the notices that refer to this
License and to the absence of any w ar r ant y; and give any other recip ients of the Program a copy
of this License along with t he Progr am.
You may charge a fee f or the physical act of transferring a copy, and you may at your option offer
warranty protection in exchange for a fee.
2. You may m odify your copy or copies of the Pr ogram or any portion of it, t hus forming a work
based on the Program, and copy and distribute such modi fi cat ions or work under the terms o f
Section 1 above, prov ided that you also meet all of these cond itions:
a) You must cause the modified files to carry prominent noti c es stating that you changed the
files and the date of any chang e.
DSO-1062D Digital Oscilloscope User Manual 74
Harmful and Poisonous Substances or Elements
b) You must cause any work that you distribute or publish, that in whole or in part contains or
is derived from the Program or any part thereof, to be lic ensed as a whole at no charge to all th ird
parties under t he t er ms o f this License.
c) If the modified prog r am n ormally reads commands i nt er actively when run, you must cause
it, when started runnin g for such interactive use in the mo st ordinary way, to print or display an
announcement including an appropriate copyright no t ice and a notice that there is no warrant y (or
else, saying that you provide a warranty) and that users may redistribute the progra m un der
these conditions, and telli ng t he user how to view a copy of this License. (Exception: if the
Program itself is interactive but does not normally print such an announcement, your work based
on the Program is not req uir ed t o print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work
are not derived from the Progr am, and can be reasonably considered independent and separate
works in themselves, then this License, and its terms, do not apply to those sections when you
distribute them as sep ar ate works. But when you distribute the sa me s ect ions as part of a whole
which is a work based on the Program, the distribution of the whole must be on the terms of
this License, whose per missions for other licensees extend t o t he entire whole, and thus t o each
and every part regardless of who wrote it.
Thus, it is not the intent of this sect i on t o claim rights or contest your rights to work writt en entirely
by you; rather, the intent is to exercise the right to control the distrib ut ion of derivative or collective
works based on the Program.
In addition, mere aggregation of another work not ba sed on th e Pro gra m with the Program (or wit h
a work based on the Program) on a volume of a storage or dis t r ibution medium does not bring t he
other work under the scop e of this License.
3. You may c opy and distribute the Progra m (or a work based on it, under Section 2) in object
code or executable form under the terms of Sections 1 and 2 above provided that you also do one
of the following:
a) Accomp any it w ith t he co mpl ete corr espon di ng m achin e-readable source cod e, w hich must
be distributed under the ter ms o f S ect ions 1 and 2 above on a medium customarily used for
software interchan ge; or,
b) Accompany it with a wr itt en offer, valid for at least three years, to give any third part y, for a
charge no more than your cost of physically performing sour ce distribution, a complete
machine-readabl e copy of the corresponding source c ode, to be distributed und er the terms
of Sections 1 and 2 above on a medi um customarily used for s oftware interchange; or,
c) Accompany it with the information you received as to t he offer to distribute corresponding
source code. (This alternative is allow ed only for noncommercial dist r ibution and only if you
DSO-1062D Digital Oscilloscope User Manual 75
Harmful and Poisonous Substances or Elements
received the program in o bject code or executable f orm wit h such an offer, in accord w it h
Subsection b above.)
The source code for a work means t he preferred form of the work for making modificati ons t o it .
For an executable work, complete source code m eans all the source code for all modules it
contains, plus any associated interface defin ition files, plus the scripts used to control compil at ion
and installation of the ex ecutable. However, as a special exce ption, the source code distribut ed
need not include anythin g t hat is normally distributed ( in either source or binary for m) w it h t he
major components (compiler, kernel, and so on) of the operating system on which t he executable
runs, unless that component itself accompanies the executable.
If distribution of execut able or object code is made by offering access to copy from a designated
place, then offering e quivalent access to copy the source code from the same place c ounts as
distribution of the source code, even though third p arties are not compell ed t o copy the source
along with the object code.
4. You may not c opy, modify, sublic ense, or dis trib ute t he Progr a m except as expressly provided
under this License. Any attempt otherwise to copy, modify, subl ice ns e or distribute the Program
is void, and will automatically terminate your rights under this License. However, parties who have
received copies, or right s, from you under this License will not have their licenses t erminated so
long as such parties remain in full compliance.
5. You are not r equired to accept this License, sin ce you have not signed it. However, nothing
else grants you perm iss ion to modify or distribute the Program or its derivative works. These
actions are prohibited by l aw if y ou do not accept this License. Therefore, by modifying or
distributing the Progra m (or any wor k based on the Program), you indicate y our acceptance of this
License to do so, and all its terms an d condit ions for copying, d istributi ng or mo difying the Program
or works based on it.
6. Each time you redistribute t he Program (or any work based on t he Program), the recipient
automatically receives a license fr om the original licensor to copy, distr ibute or modify the Program
subject to these terms and c onditions. You may not impose any furt her restrictions on the

by third parties to this Lic ense.
7. If, as a consequence of a cour t judg m ent or allegation of patent infringement or for any other
reason (not limited to patent issues), conditions ar e i mp os ed on you (whether by cour t or der,
agreement or otherwis e) t hat cont r adict the conditions of this License, they do not excuse y ou
from the conditions of this License. If you cannot distribute so as t o sat isfy simultaneously y our
obligations under this L icense and any other pertine nt obli gat ions, then as a consequence you
may not distribute the Pro gr am at all. For example, if a patent licens e would not permit
royalty-free redistributi on of the Program by all thos e who receive copies directly or indirectly
through you, then the only way you could satisfy both it and this License would be to refrain
entirely from distribution of the Program.

It is not the purpose of this sectio n t o ind uc e you to infringe any patents or other propert y right

How to Apply These Terms to Your New Progr ams
If you develop a new program, and you want it to be of the greatest possible use to the public ,
the best way to achieve this is to ma ke it free software w hich ev er yone can redistribute and
change under these terms .
To do so, at tach the following notices to the program. It is safest to attach them to the start of
each source file to most effectively conv ey the exclusion of warranty; and each file should have at
least the "copyright" line and a pointer to where the full notic e is found.
<one line to give the program's name and a brief idea of what it does.>

If the program is interactiv e, ma ke it output a short notice like this w hen it starts in an interact ive
mode:
Gnomovision version 69, Copyright (C) year na me o f author Gnomovision comes with
ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are
welcome to redistribute it under certain conditions; type `show c' for det ai ls.
The hypothetical commands `show w' and `show c' should sh ow the appropriate par ts of the
General Public License. Of course, the commands you use may be ca ll ed something other than
`show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your
program.
You should also get your employer (if you work as a pr ogr ammer) or your school, if any, to sign a
"copyright disclaimer" for the program, if necessar y. Here is a sample; alter the names :
