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.
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.

Press the MATH button to display the Math Menu. Use the options to select the Source
channel, Window algorithm, and FFT Zoom factor. You can display only one FFT
spectrum at a time. You can select “Full screen” or “Split” in “Display” option to display
FFT waveform on full screen or display channel waveform and its FFT waveform on half
screen at a time.
Picture2.6-10 FFT function
3. Select FFT window
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 cause
discontinuities in the signal that introduce high-frequency transients.
According to the tested options and source speciality, make sure the window you
need to use.

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 “POSITION” 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.
32
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.
2.7.2 Window Zone
Use the Delayed option to define a segment of a waveform to see more detail. The
Window time base setting cannot be set slower than the Main time base setting.
You can turn the Horizontal Position and SEC/DIV controls to enlarge or diminish
waveforms in the Window Zone.
“M” Mean main time base, “W” mean window time base.. It is also a arrow on the scale
top to show the vertical position.
If you want to see a section of the waveform in detail, follow these steps:
(1) Press the “HORI MENU” button to enter the “Horizontal menu”.
(2) Turn the “S/div” knob to change the main timebase scale.
(3) Press the “Delayed” option button to select “On”.

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.
There are three buttons and one knob in the Trigger area. See picture.2-29:
Picture 2.8-1
“TRIG MENU” Button: Press the “TRIG MENU” button to display “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.
LEVEL knob
34
Pre-trigger/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 pre-trigger and delayed trigger can be surveyed. More data of pre-trigger and 1s
delayed trigger can be surveyed by adjusting the horizontal position.
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 (pre-trigger 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).
2.8.2 Trigger Type

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.
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.
51
Picture 2.9-2 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 2.9-3 Peak Detect mode
Average: The oscilloscope acquires several waveforms, averages them, and
52
displays the resulting waveform.
Advantage: You can use this mode to reduce random noise.
Picture 2.9-4 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: The scope 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.
53
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 pre-trigger.
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.
Time Base: 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.
Use S/div knob to adjust the time base to a horizontal scale suits your purpose,
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.

2.10.1 X-Y Format
Use the XY format to analyze phase differences, such as those represented by
Lissajous patterns. The format plots the voltage on channel 1 against the voltage on
channel 2, where channel 1 is the horizontal axis and channel 2 is the vertical axis. The
oscilloscope uses the untriggered Sample acquisition mode and displays data as dots.
XY mode has a breakthrough that traditional oscilloscopes restrict sampling rate at
1MSa/s
support 25KSa/s250MSa/s (1-2.5-5 sequence) adjusted ;
Operation steps
Channel 1 “Volt/div” and vertical “POSITION” set up the horizontal scale and
position.
Channel 2 “Volt/div” and vertical “POSITION” set up the horizontal scale and
position.
Turn the “S/div” knob to adjust the sampling rate

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 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.
