III. Operations Instruction

Relevant operations of this software.

1.How to Set the Probe Attenuation Coefficient

The probe has several attenuation coefficients, which will influence the vertical scale factor of the oscilloscope. To change or check the probe attenuation coefficient in the menu of oscilloscope:

(1) Click to show Function menu, choose "Channel". (2) Set "Probe Rate" to the proper value corresponding to the probe. This setting will be valid all the time before it is changed again.

Caution:

The default attenuation coefficient of the probe in the

software is

preset to 10X.

Make sure that the set value of the attenuation switch in the probe is the same as the menu selection of the probe attenuation coefficient

in the software.

The set values of the probe switch are 1X and 10X.

Figure: Attenuation Switch

Caution:

When

the attenuation switch is set to 1X, the probe will limit the

bandwidth of the oscilloscope in 5MHz. To use the full bandwidth of

the oscilloscope, the switch must be set to 10X.

2.How to Set the Vertical System

You can set the corresponding parameters of vertical system in the Channel window (18/19 in II. User Interface).

In the voltage division list, you can select the proper value. Take VDS3102 for instance.

You can set the zero point position through the control bar to regulate of the vertical display position of the signal. You can also drag the zero point position pointer (22, 23 in II. User Interface).

Drag the slider up to increase, down to decrease; the further from the center, the higher the changing speed is.

Keyboard Shortcuts

Q: The voltage division of Channel 1 decreases one

level

The voltage division of Chann el 1 i ncr eases one level

W: The voltage division of Channel 2 decreases one level

S: The voltage division of Channel 2 increases one level

Cymometer

It is a 6-digit cymometer. The cymometer can measure frequencies from 2Hz to the full bandwidth. Only if the measured channel has triggering signal and in Edge mode, it can measur e frequency correctly. In the Single tri g ger mode, it is a one channel cymomet er and i t can only measure the frequency of the triggering channel. In the ALT trigger mode, it is a two channel cymometer and it can measure the frequency of two channels.

3.How to Set the Horizontal System

You can set the corresponding parameters of horizontal system in the Capture&period window (17 in II. User Interface).

You can use Horizontal Trigger Position cont r ol bar to a djus t th e hor i z ontal posi ti on o f the s ig nal in t he wav eform w indow . You c an also dr ag th e red pointer to adjust it (3 in II. User Interface).

Note: Different machines have different ranges of time base, here just take VDS3102 for instance. The further from the center, the higher the changing speed is.

4.How to Set the Trigger System

Trigger determines when VDS starts to acquire data and display waveform. Once trigger is set correctly, it can convert the unstable display to meaningful waveform.

When VDS starts to ac quire data, it will coll ect en oug h data to draw waveform on left of trigger point. VD S c o nti nu es t o ac q ui r e d ata while waiting for trigger condition to occur. Once it detects a trigger it will acquire enough data continuously to draw the waveform on right of trigger point.

Click to show Function menu, choose "Trigger". You can also click in the right bottom window to show it.

Trigger Control

The oscilloscope provides two trigger types: single trigger and alternate trigger.

Single trigger: Use a trigger level to capture stable waveforms in two channels simultaneously. Alternate trigger: Trigger on non-synchronized signals. The Single Trigger and Alternate Trigger menus are described respectively as follows:

Single trigger

1. In Trigger menu, choose "Single" (the chosen label has a mark).

2. Choose Source.

3. Choose Mode. Single trigger has four modes: edge trigger, video trigger, slope trigger and pulse trigger.

Edge Trigger: It occurs when the trigger input passes through a specified voltage level with the specified slope. Video Trigger: Trigger on fields or lines for standard video signal.

Slope Trigger: The oscilloscope begins to trigger according to the signal rising or falling speed. Pulse Trigger: Find pulses with certain widths.

The four trigger modes in Single Trigger are described respectively as follows:

Edge Trigger

Choose Mode as "Edge". An edge trigger occurs on trigger threshold value of input signal. Select Edge trigger mode to trigger on rising edge or falling edge.

Set in Trigger menu: (1) Choose "Rise" to trigger on rising edge.

Choose "Fall" to trigger on falling edge.

(2) Click the voltage value after "Trigger" to show slider bar. You can also drag "13. Trigger point" in II. User Interface

(3) Choose Trig Mode.

Auto: Acquire waveform even no trigger occurs. Normal: Acquire waveform when trigger occurs. Single: When trigger occurs, acquire one waveform then stop.

(4) Set Hold Off: When trigger occurs, acquire one waveform then stop (100ns~10s).

Setting method: "+", "++", "+++" is the position of digit that will be changed. "+" represents the last digit, "++" represents the middle di g i t, "+++" represents the first digit. Eg. When "+" is chosen, click ▲, the last digit will be increased by 1. Click "Reset" to set Holdoff time as default value (100ns).

Set in Trigger window:

Force: Force to create a trigger signal and the function is mainly used in "Normal" and "Single" mode.

Video Trigger

Choose Mode as "Video" to trigger on fields or lines of NTSC, PAL or SECAM standard video signals. (1) Select video modulation: NTSC, PAL or SECAM. (2) Set trigger synchronization: Line, Field, Odd filed, Even filed or Line Number. When "Line Number" is selected, you can set the line

number.

(3) Set Hold Off. About the setting method, refer to Edge Trigger.

Slope Trigger

Choose Mode as "Slope" to set the oscilloscope as the positive/negative slope trigger within the specified time. (1) Select slope condition. (2) Set slope time. (3) Set the High level upper limit and Low level lower limit.

(4) Set Trig Mode and Hold Off. About the setting method, refer to Edge Trigger. Slew rate = (High level - Low level) / Settings

Pulse Width Trigger

Choose Mode as "Pulse". Pulse t rigg er occur s according to the w idth of puls e. The a bnormal signal s can be detect ed throug h setti ng up the pulse width condition. (1) Select pulse width condition and set time. (2) Set trigger level.

(3) Set Trig Mode and Hold Off. About the setting method, refer to Edge Trigger.

Alternate trigger

The Mathematical Manip ula tion function is used to show the results of the addition, multiplication, division and subtraction operations between Channel 1 and Channel 2, and the FFT operation of Channel 1 or Channel 2.

Math of dual waveform

1. Turn on CH1 and CH2.

2. Click to show Function menu, choose "Math". Check "Math".

3. Choose the factors and operator. Select the voltage division of M. The software transforms the waveform data of the two factors into selec te d voltage division of M and calculates. The green calculated waveform M is displayed in the screen.

Using FFT function

The FFT (fast Fourier transform) math function mathematically converts a time-domain waveform into its frequency components. It is very useful for analyzing the input signal on Oscilloscope. You can match these frequencies with known system frequencies, such as system clocks, oscillators, or power supplies.

FFT function in this oscilloscope transforms 2048 data points of the time-domain signal into its frequency components mathematically and the final frequency contains 1024 points ranging from 0Hz to Nyquist frequency.

Taking the FFT operation for example, the operation steps are as follows:

1. Click to show Function menu, choose "Math". Check "FFT". The user interface is switched into Three View mode.

2. Set "Channel", "Window", "Format", "Scale", "Frequency Base".

3. You can drag anywhere in FFT window to move the signal up and down and side to side.

To select the FFT window

There are four FFT windows. Each one has trade-offs between frequency resolution and magnitude accuracy. What you want to measure and your source signal characteristics help you to determine which window to use. Use the following guidelines to select the best window.

Type

Characteristics

Window

Hamming

Better solution for magnitude than Rectangle,

and good fo

r frequency as well. It has slightly

better frequency resolution than Hanning. Recommend to use for: 

Sine, periodic and narrow band random

noise.



Transients or bursts where the signal levels before and after the event are significantly

different.

Rectangle

Best solution for frequency, wor st for magnit ude. Best type for measuring the frequency spectrum

of non-repetitive

signals and measuring

frequency components near DC. Recommend to use for: 

Transients or bursts, the signal level before

and after the event are nearly equal.

 Equal-

amplitude sine waves with

frequencies those are very close.



Broadband random noise with a relatively

slow varying spectrum.

Blackman

Best solution for magnitude, wor st for freq uency.

Recommend to use for:  Singl

e frequency waveforms, to find higher

order harmonics.

Hanning

Good for magnitude, but poorer frequency

resolution than Hamming. Recommend to use for: 

Sine, periodic and narrow band random

noise.



Transients or bursts where the signal levels

before

and after the event are significantly

different.

The figures below are examples for measuring sine wave with a frequency of 1kHz under the selection of four different windows for FFT:

Figure: Hamming window

Figure: Rectangle window

Figure: Blackman window

Figure: Hanning window

Notes for using FFT

 Select "Scale" to magnify the FFT waveform if necessary.  Use the default dB scale for details of multiple frequencies, even if they have very different amplitudes. Use the Vrms scale to compare

frequencies.

 DC component or off set c an c ause inc orr ect magnitude values of F FT w avefor m. To mi nimiz e the DC com pone nt, c hoos e AC Coupl in g on th e

source signal.

 To reduce random noise and aliased components in repetitive or single-shot events, set the oscilloscope acquisition mode to average.

What is Nyquist frequency?

The Nyquist frequency is the hig hest freq uenc y that any real -time di git iz ing osci llos cope can acqui re wi thout ali asin g. Thi s freq uency is hal f of th e sample rate. Frequencies above the Nyquist frequency will be under sampled, which causes aliasing. So pay more attention to the relation between the frequency being sampled and measured.

Note：

In FFT mode, only support to set coupling, voltage division and zero position in Channel window, other operations are prohibited. If you want to enter other menus, uncheck "FFT" first.
