1.3 Probe
1.3.1 Probe Safety
A guard around the probe body provides a finger barrier for protection from electric
shock.
Picture 1-6
Connect the probe to the oscilloscope and connect the ground terminal to ground
before you take any measurements.
Note: ● To avoid electric shock when using the probe, keep fingers behind the guard
on the probe body.
● To avoid electric shock while using the probe, do not touch metallic
portions of the probe head while it is connected to a voltage source.
Connect the probe to the oscilloscope and connect the ground terminal to
ground before you take any measurements.
1.3.2 Probe Attenuation Setting
Probes are available with various attenuation factors which affect the vertical
scale of the signal. The Probe Check function verifies that the Probe attenuation
option matches the attenuation of the probe.
You can push a vertical menu button (such as the CH 1 MENU button), and
select the Probe option that matches the attenuation factor of your probe.
Note. The default setting for the Probe option is 1X.
Be sure that the attenuation switch on the probe matches the Probe option in the
10
oscilloscope. Switch settings are 1X and 10X.
Note. When the attenuation switch is set to 1X, the probe limits the bandwidth of the
oscilloscope to 10MHz(according to Probe spec). To use the full bandwidth of the
oscilloscope, be sure to set the switch to 10X
1.3.3 Probe Compensation
As an alternative method to Probe Check, you can manually perform this
adjustment to match your probe to the input channel.
Picture1.3-2
1. Set the Probe option attenuation in the channel menu to 10X. Set the switch to 10X
on the probe and connect the probe to channel 1 on the oscilloscope. If you use the
probe hook-tip, ensure a proper connection by firmly inserting the tip onto the
probe.
2. Attach the probe tip to the PROBE COMP~3V connector and the reference lead
to the PROBE COMP Ground connector. Display the channel and then push the
“AUTO” button.
3. Check the shape of the displayed waveform.

4. If necessary, adjust your probe. Repeat as necessary.
1.4 Self Calibration
The self calibration routine lets you optimize the oscilloscope signal path for
maximum measurement accuracy. You can run the routine at any time but should
always run the routine if the ambient temperature changes by 5℃ or more.
To compensate the signal path, disconnect any probes or cables from the front-panel
input connectors. Then, push the UTILITY button→ “ Next Page 1/3” → “Do Self
Cal” option and follow the directions on the screen.

Note:● The oscilloscope vertical response rolls off slowly above its bandwidth (60
MHz, 100 MHz) , which depending on the model, or 20 MHz when the
Bandwidth Limit option is set to “On”. Therefore, the FFT spectrum can
show valid frequency information higher than the oscilloscope bandwidth.
However, the magnitude information near or above the bandwidth will not
be accurate.
● If the channel is set to DC coupling,you can quickly measure the DC
component of the signal by simply nothing its distance from the ground
symbol.
● If the channel is set to AC coupling,the DC component of the signal is
blocked allowing you to use greater sensitivity to display the AC
component of the signal.
Setting up the CH1、CH2 Channels
Each channel has its own separate Menu. The items are set up separately
according to each channel.
1. Set up the channel couple
Take the CH1 for example, the tested signal is a sine wave signal with DC
deflection:
● Press“CH1”→“Coupling”→“AC”, Set to AC couple mode. It blocks the DC

Windows reduce spectral leakage in the FFT spectrum. The FFT assumes that the YT
waveform repeats forever. With an integral number of cycles, the YT waveform starts
and ends at the me amplitude and there are no discontinuities in the signal shape A
non-integral number of cycles in the YT waveform causes the signal start and end
points to be at different amplitudes. The transitions between the start and end points

NOTE:● The FFT of a waveform that has a DC component or offset can
cause incorrect FFT waveform magnitude values. To minimize
the DC component, choose AC Coupling on the source
waveform.
● To display FFT waveforms with a large dynamic range, use the
dBVrms scale. The dBVrms scale displays component
magnitudes using a log scale.
● The Nyquist frequency is the highest frequency that any real-time
digitizing oscilloscope can acquire without aliasing. This
frequency is half that of the sample rate, provided it is within the
analog bandwidth of the oscilloscope. Frequencies above the
Nyquist frequency will be under sampled, which causes aliasing.

2.7.1 Horizontal control knob
You can use the horizontal controls to change the horizontal scale and position
of waveforms. The horizontal position readout shows the time represented by the
center of the screen, using the time of the trigger as zero. Changing the horizontal
scale causes the waveform to expand or contract around the screen center.
■ Horizontal “POSITION” knob
1. Adjust the horizontal position of all channels and math waveforms (the position of
the trigger relative to the center of the screen). The resolution of this control varies
with the time base setting.
2. When you press the horizontal “POSITON” Knob, you can set the horizontal
position to zero.
■“S/div” knob
1. Using to change the horizontal time scale to magnify or compress the waveform. If
waveform acquisition is stopped (using the RUN/STOP or SINGLE button), turn the
S/div knob to expand or compress the waveform.
2. Select the horizontal time/div (scale factor) for the main or the window time base.
When Window Zone is enabled, it changes the width of the window zone by
changing the window time base.
■ Display scan mode:
When the SEC/DIV control is set to100 ms/div or slower and the trigger mode
is set to Auto, the oscilloscope enters the scan acquisition mode. In this mode, the
waveform display updates from left to right. There is no trigger or horizontal position
control of waveforms during scan mode.

2.8 Trigger System
The trigger determines when the oscilloscope starts to acquire data and display a
waveform. When a trigger is set up properly, the oscilloscope converts unstable
displays or blank screens into meaningful waveforms.
Here are three buttons and one Knob in the Trigger area. Showing as Picture.2-29:
LEVEL knob
Picture 2-29
■ “TRIG MENU” Button: Press the “TRIG MENU” Button to display the “Trigger
Menu”.
■“LEVEL” Knob: The LEVEL knob is to set the corresponding signal voltage of
trigger point in order to sample. Press the “LEVEL” knob can set trigger level to
zero.
■“SET TO 50%” Button: Use the “SET TO 50%” button to stabilize a waveform
quickly. The oscilloscope can set the Trigger Level to be about halfway between the
minimum and maximum voltage levels automatically. This is useful when you
connect a signal to the EXT TRIG BNC and set the trigger source to Ext or Ext/5.
■“FORCE” Button: Use the FORCE button to complete the current waveform
acquisition whether the oscilloscope detects a trigger or not. This is useful for
SINGLE acquisitions and Normal trigger mode.
■ Pretrigger/Delayed trigger: The data before and after trigger the trigger position
is typically set at the horizontal center of the screen, in the full-screen display the
6div data of pretrigger and delayed trigger can be surveyed. More data of pretrigger
and 1s delayed trigger can be surveyed by adjusting the horizontal position.
40
The feature is very useful because you can see the events that led up the trigger point
everything to the right of the trigger point is called posttrigger information the
amount of delay range (pretrigger and posttrigger information) available is dependent
on the sweep speed selected.
2.8.1 Signal Source
You can use the Trigger Source options to select the signal that the oscilloscope uses
as a trigger. The source can be any signal connected to a channel BNC, to the EXT
TRIG BNC or the AC power line (available only with Edge triggers).

2.8.3 Coupling
Use the “Coupling” to make sure the signal that passes the trigger circuit. It is useful
for us to gather a steady wave form.
If you use the trigger coupling, you should press the “TRIGGE” button and then
select “edge” or “Pulse” trigger. Then select the “coupling” option.
2.8.4 Position
The horizontal position control establishes the time between the trigger position and
the screen center. You can adjust the horizontal “POSITION” knob control to view
waveform data before the trigger, after the trigger, or some of each. When you
change the horizontal position of a waveform, you are changing the time between the
trigger and the center of the display actually. (This appears to move the waveform to
the right or left on the display.)
2.8.5 Slope & Level
The Slope and Level controls help to define the trigger. The Slope option (Edge
trigger type only) determines whether the oscilloscope finds the trigger point on the
rising or the falling edge of a signal.

●. Trigger coupling affects only the signal passed to the trigger
system. It does not affect the bandwidth or coupling of the
signal displayed on the screen.
● Normal Polarity Sync triggers always occur on negative-going
orizontal sync pulses. If the video waveform has positive-going
horizontal sync pulses, use the Inverted Polarity selection.
2.8.6 Trigger Holdoff
You can use the Trigger Holdoff function to produce a stable display of complex
waveforms. Holdoff is time between when the oscilloscope detects one trigger and
when it is ready to detect another. The oscilloscope will not trigger during the holdoff
time. For a pulse train, you can adjust the holdoff time so the oscilloscope triggers
only on the first pulse in the train.

Display system sampling rate.
When you acquire a signal, the oscilloscope converts it into a digital form and
displays a waveform. The acquisition mode defines how the signal is digitized and
the time base setting affects the time span and level of detail in the acquisition.
■ Sampling: In this acquisition mode, the oscilloscope samples the signal in evenly
spaced intervals to construct the waveform. This mode accurately represents signals
most of the time.
Advantage: You can use this mode to reduce random noise.
56
Disadvantage: This mode does not acquire rapid variations in the signal that may
occur between samples. This can result in aliasing may cause narrow pulses to be
missed. In these cases, you should use the Peak Detect mode to acquire data.
Picture 2-41 Sampling modes
■ Peak Detect: Peak Detect mode capture the maximum and minimum values of a
signal Finds highest and lowest record points over many acquisitions.
Advantage: In this way, the oscilloscope can acquire and display narrow pulses,
which may have otherwise been missed in Sample mode.
Disadvantage: Noise will appear to be higher in this mode.
Picture 2-42 Peak Detect mode
■
Average: The oscilloscope acquires several waveforms, averages them, and
displays the resulting waveform.
Advantage: You can use this mode to reduce random noise.
57
■
Picture 2-43 Average mode
Equivalent Time Sampling:
The equivalent time sampling mode can achieve up to 20 ps of horizontal resolution
(equivalent to 50GSa/s). This mode is good for observing repetitive waveforms.
■ Real Time Sampling: ADS1000 has the highest Real-time sampling rate
up to 1GSa/s.
■ “RUN/STOP” Button: Press the RUN/STOP button when you want the
oscilloscope to acquire waveforms continuously. Press the button again to stop the
acquisition.
■ “SINGLE” Button: Press the SINGLE button to acquire a single waveform. Each
time you push the SINGLE button, the oscilloscope begins to acquire another
waveform. After the oscilloscope detects a trigger it completes the acquisition and
stops.
When you push the RUN/STOP or SINGLE buttons to start an acquisition, the
oscilloscope goes through the following steps:
1). Acquire enough data to fill the portion of the waveform record to the left of the
trigger point. This is also called the pretrigger.
2). Continue to acquire data while waiting for the trigger condition to occur.
3). Detect the trigger condition.
4). Continue to acquire data until the waveform record is full.
5). Display the newly-acquired waveform.
58
■ Base time: The oscilloscope digitizes waveforms by acquiring the value of an
input signal at discrete points. The time base allows you to control how often the
values are digitized.
To adjust the time base to a horizontal scale that suits your purpose, use the S/div
knob.
■ Time Domain Aliasing:
Aliasing occurs when the oscilloscope does not sample the signal fast enough to
construct an accurate waveform record. When this happens, the oscilloscope
displays a waveform with a frequency lower than the actual input waveform, or
triggers and displays an unstable waveform.

2.11 Measure System
The Oscilloscope displays the voltage in relation to time and test the wave form
displayed. There are scale, Cursor and auto measure modes.
2.11.1 Scale Measurement
This method allows you to make a quick, visual estimate. For example, you
might look at a waveform amplitude and determine that it is a little more than 100
mV. You can take simple measurements by counting the major and minor graticule
divisions involved and multiplying by the scale factor. For example, if you counted
five major vertical graticule divisions between the minimum and maximum values of
a waveform and knew you had a scale factor of 100mV/div, then you could easily
calculate your peak-to-peak voltage as follows:
5 divisions x 100 mV/division = 500 mV.

4.2 Troubleshooting
1. After the oscilloscope is powered on,the screen remains dark ,please do as
following steps:
⑴ Check the power cable’s connection.
⑵ Ensure the power switch is turned on.
⑶ After the inspections above,restart the oscilloscope.
⑷ If the oscilloscope is still not used after the checking, please connect with
ATTEN company.
2. If there is no signal wave in the screen after gathering the signal, please do as
following steps:
(1)Check the probe connecting with the signal cable or not
(2)Check the signal cable connecting with the BNC connector or not.
(3)Check the probe whether connect with the goods tested or not.
(4)Check the tested goods produce the signal or not.
(5)Gather the signal again.
3. The value of the tested voltage is 10 times higher/lower than the real one ,
please do as following steps::
Check the attenuation quotiety whether match the probe attenuation proportion
or not.
4.Display the wave, but not steady , please do as following steps::
(1) Check the signal source on the trigger interface whether or not match the signal
channel.
(2) Check the trigger mode: normal signal should use the “edge” trigger mode. The
video signal should use the “Video” Trigger mode. The signal would display
steady, only using the matching trigger mode.
(3) Attempt to change the “ coupling” into “HF Reject” or “LF Reject” display, so
that the High/low frequency noise disturb the trigger should be filtrated
5. Press “RUN/STOP” button, but no display.
112
Check the trigger mode on the trigger interface whether or not in the “normal” or
“single”, and check the trigger level is whether or not over the wave range. If yes,
please put the trigger level to the middle position or set the trigger mode to the
“Auto” position. In another hand, you could choose the “Auto” button to set up
automatically.
6. After the Acquisition is set to Averages or Display Persistence time is set too
long, the waveform refreshes slowly.
It is normal in these settings
7. The signal is displayed as ladder like waveform
(1)This phenomena is normal. The time base maybe is too slow .you should turn
the horizontal SCALE knob to increase horizontal resolution to improve the
display.
(2) Maybe the display Type is set to “Vectors”, You could set it to Dots mode to
improve the display.
