When the measured signal is unstable, displayed waveform presents jump; long-term

observation may cause eye fatigue. Digital Oscilloscope offers the selection of fast/slow
display function, press F3 (F/S), fast display can be switched to slow display, which can
efficiently improve eye fatigue. “Slow” turns to yellow at status bar of interface, means
activated.

•If press again, switch back to fast display, “Fast” turns to yellow, means fast display
activated.

•Default fast display after star

t up.

2-6 Vertical System

•Press “ ”to adjust vertical system, default attenuation ratio, that is, preselected frequency
(xxV/div) of adjusting input end after start up presents the status of last shutdown.

•While selecting DC coupling, as direct current exist in waveform, it may turn to one side,
press “MODE”, switch function of “

” to adjust waveform up and down position, make the

waveform back to middle position by pressing “

xxKSa/S.

•Press “MODE” then “

” if user wants to change the trigger horizontal position in memory

(trigger displacement).

2-8 Trigger System

Trigger function confirms the time of collecting data

and displaying waveform for the
oscilloscope.After correctly set up the trigger, the oscilloscope can switch unstable displayed
result to meaningful waveform.

-

•

2-8-1 Trigger Mode

•2 kinds of trigger mode for the oscilloscope: raising edge and falling edge. When signal
voltage across trigger electrical level, raising and falling edge of input signal is adopted for
triggering.

•Raising edge setup: press “setup”

→ “trigger” → “raising edge” → “save and quit”.

•Falling edge setup: press “setup”

→ “trigger” → “falling edge” → “save and quit”.

•If select “setup”

→ “trigger” → “no trigger” → “save and quit”, the oscilloscope may lose

synchronizing signal and any signal measured by fast display.

2-9 Channel

•Oscilloscope vertical response should be slightly greater than its bandwidth, so that FFT
frequency spectrum can be higher than effective frequency of oscilloscope bandwidth.
However, amplitude close to or higher than the bandwidth will not be accurate.

•If channel coupling mode is DC, user can measure DC component of signal by observing
the difference between waveform and signal ground.

•If coupling mode is AC, DC

component is filtered in the signal. This mode makes user

easily display the AC component of signal with higher sensitivity.

Channel Settings

•Channel coupling settings

Measured signal is sinusoidal signal containing DC bias:

•Press “setup”

→ “coupling”→”AC”, select AC coupling mode. DC component in measured

signal is separated.

•Press “setup”

→ “coupling” → “DC”, select DC coupling mode. DC and AC component in

measured signal can all pass.

2-10 FFT frequency spectrum analysis

Time signal can be converted into frequency component (frequency spectrum) by using FFT
mathematical operation (Fast Fourier Transform). Observe following signals by FFT mathematical
mode:

•Analyze harmonic wave in power line

•Measure harmonic wave content and distortion in system

•Measure impulse response of filter and system

•Analyze oscillation

13/08/2017 Version No. 001

Oscilloscope Section/English Oscilloscope Section/English

13/08/2017 Version No. 001 4140

If adopt FFT (Fast Fourier Transform) mode, take following steps:

1. Set up time domain waveform

•Press “AUTO” to display proper waveform.

•If displayed waveform shows unsatisfactory, press

“

” and “ ” for adjustment.

•Press F4 (FFT), the oscilloscope may adopt the 256
central points of time domain waveform to calculate
FFT frequency spectrum.

•According to Nyquist criterion, press “

”, make

sampling rate up to at least 2 times of input signal
frequency.

2. FFT frequency spectrum display
Press “F4” FFT button, display FFT frequency spectrum, in which a channel waveform

and FFT waveform are shown in the split screen.
FFT windows instructions

As the oscilloscope takes FFT transform for time

records of limited length, FFT calculation mode bases
on repeated YT waveform. In this case, if the cycle is
integer, frequency values of YT waveform are the same
at the beginning and the end, the waveform may not be
interrupted. However, if the YT waveform cycle is not

integer, frequency values shows different at the beginning
and the end, high-frequency transient interrupts occur at
connecting part. That is so-called “leak

age” in frequency
domain. Therefore, in order to avoid leakage, multiply
a window function with the original waveform, forcing
the values at the beginning and the end to 0.

3. Position FFT frequency spectrum

•“ ” button can still be pressed under FFT interface to change sampling rate, to realize
horizontal amplification or minification;

•Adjust “

” to realize vertical amplification or minification.

4. Measure FFT frequency spectrum by cursor

•Two kinds of measurement can be taken for FFT spectrum by using cursor: amplitude
(relative value) and frequency (unit: Hz).

•Under FFT interface, press F2 (

) or F3 ( ) according to prompt bar to move red

cursor, corresponding frequency and relative amplitude can be measured.

Picture 2-10-1(split screen)

Picture2-10-2

Note:

•DC component or deviation existed in signal may cause error or deviation in FFT waveform
component part. Select DC coupling mode to reduce AC component.

•Nyquist frequency: for waveform, of which highest value ups to F, sampling rate of 2F must
be adopted to rebuild the waveform, that is also called Nyquist criteria, “F” means Nyquist
frequency, “2F” means Nyquist rate.

2 11 Signal Capture System

•Real-time sampling: the memory space should be full for every sampling. Real-time sampling
rate ups to 50MSa/s.

•The system is under default continuous sampling state after startup, press “HOLD” if user
wants to take static measurement, press the same button again to turn back to continuous
sampling state.

•“REC” button: if the user needs the oscilloscope to take sample of enough data to analyze
a series of numbers, press “REC”, the oscilloscope may continuously take data sample of

10 pages for measurement analysis.

•Time base: the oscilloscope takes sample of input signal values at discontinuous points to
digitalize the waveform. Frequency of value digitalization can be controlled by adopting time
base. Press “

”, adjust the time base to a horizontal level to satisfy user’s needs,

•False wave phenomenon: if the speed of sampling is not fast enough, causing inaccurate
waveform records, “false wave phenomenon” occur. In this case, the oscilloscope displays
the waveform by a frequency which is below actual input waveform’s frequency, or triggers
and displays unstable waveform. Therefore, press “AUTO” to auto search for the first
measurement of new signal, to confirm the basic frequency of this signal.

2-13 Measuring System

The oscilloscope displays forms of voltage relative to time, and helps user measure and display
waveforms. Two ways of measurements can be adopted: Scale measurement or cursor

measurement.

2-13-1 Scale Measurement

Fast and direct evaluation can be done by this way, for exampl

e, waveform amplitude can be
observed to judge whether it’s 0.8V or not.
By calculating relevant primary and secondary scale division, then multiplying by proportion
factor, simple measurement can be taken.
For example, if four main vertical scale divisions between the waveform peak and base are

figured out, proportion factor is 200 mV/division, peak value voltage can be calculated by the
following method: 4 divisions * 200mV/div= 0.8V
