How to Implement the General Inspection After you get a new oscilloscope, it is recommended that you should make a check on the instrument according to the following steps: 1. Check whether there is any damage caused by transportation. If it is found that the packaging carton or the foamed plastic protection cushion has suffered serious damage, do not throw it away first till the complete device and its accessories succeed in the electrical and mechanical property tests. 2.
3. Push the Autoset Button on the front panel. The square wave of 1 KHz frequency and 5V peak-peak value will be displayed in several seconds (see Figure 1-5). Figure 1-5 Auto set Check CH2 by repeating Step 2 and Step 3. How to Implement the Probe Compensation When connect the probe with any input channel for the first time, make this adjustment to match the probe with the input channel. The probe which is not compensated or presents a compensation deviation will result in the measuring error or mistake.
Figure 1-7 Adjust Probe 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) Push the function menu button of the used channels (CH1 or CH2 button). (2) Select Probe in the right menu; turn the M knob to select the proper value in the left menu corresponding to the probe.
How to Use the Probe Safely The safety guard ring around the probe body protects your finger against any electric shock, shown as Figure 1-9. Figure 1-9 Finger Guard Warning: To avoid electric shock, always keep your finger behind the safety guard ring of the probe during the operation. To protect you from suffering from the electric shock, do not touch any metal part of the probe tip when it is connected to the power supply.

Hamming Rectangle Blackman Window Select window for FFT. Hanning Kaiser Bartlett Vrms Select Vrms for Format. Format dB Select dB for Format.
Type Characteristics Window Better solution for magnitude than Rectangle, and good for frequency as well. It has slightly better frequency resolution than Hanning. 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. Best solution for frequency, worst for magnitude.
Notes for using FFT 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 offset can cause incorrect magnitude values of FFT waveform. To minimize the DC component, choose AC Coupling on the source signal. To reduce random noise and aliased components in repetitive or single-shot events, set the oscilloscope acquisition mode to average.
Horizontal Position and Horizontal Scale. 1. Horizontal Position knob: this knob is used to adjust the horizontal positions of all channels (include those obtained from the mathematical manipulation), the analytic resolution of which changes with the time base. 2. Horizontal Scale knob: it is used to set the horizontal scale factor for setting the main time base or the window. 3. Horizontal HOR button: push it to switch between the normal mode and the wave zoom mode.
Force: Force to create a trigger signal and the function is mainly used in "Normal" and "Single" mode. Trigger Menu: The button that activates the trigger control menu.

To learn about how to operate the software, you can push F1 in the software to open the help document. Here is how to connect with PC via USB port. (1) Install the software: Install the Oscilloscope communication software on the supplied CD.
6. Demonstration Example 1: Measurement a Simple Signal The purpose of this example is to display an unknown signal in the circuit, and measure the frequency and peak-to-peak voltage of the signal. 1. Carry out the following operation steps for the rapid display of this signal: (1) Set the probe menu attenuation coefficient as 10X and that of the switch in the probe switch as 10X (see "How to Set the Probe Attenuation Coefficient" on P13).
Example 2: Gain of a Amplifier in a Metering Circuit The purpose of this example is to work out the Gain of an Amplifier in a Metering Circuit. First we use Oscilloscope to measure the amplitude of input signal and output signal from the circuit, then to work out the Gain by using given formulas. Set the probe menu attenuation coefficient as 10X and that of the switch in the probe as 10X (see "How to Set the Probe Attenuation Coefficient" on P13).
Example 3: Capturing a Single Signal It's quite easy to use Digital Oscilloscope to capture non-periodic signal, such as a pulse and burr etc. But the common problem is how to set up a trigger if you have no knowledge of the signal? For example, if the pulse is the logic signal of a TTL level, the trigger level should be set to 2 volts and the trigger edge be set as the rising edge trigger. With various functions supported by our Oscilloscope, user can solve this problem by taking an easy approach.
Figure 0-3 Capturing a Single Signal Example 4: Analyze the Details of a Signal Noise is very common inside most of the electronic signal. To find out what's inside the noise and reduce the level of noise is very important function our oscilloscope is capable to offer. Noise Analysis The level of noise sometime indicates a failure of electronic circuit. The Peak Detect functions acts an important role to help you to find out the details of these noise.
Separate Noises from the Signal When focusing on signal itself, the important thing is to reduce the noise level as lower as possible, this would enable user to have more details about the signal. The Average function offered by our Oscilloscope can help you to achieve this. Here are the steps for how to enable Average function. (1) Push the Acquire button to display the right menu. (2) In the right menu, select Acqu Mode as Average.
output of the network. (3) Push the Autoset button, with the oscilloscope turning on the signals of the two channels and displaying them in the screen. (4) Turn the Vertical Scale knob, making the amplitudes of two signals equal in the rough. (5) Push the Acquire button to display the right menu. (6) In the right menu, select XY Mode as ON. The oscilloscope will display the input and terminal characteristics of the network in the Lissajous graph form.
Example 6: Video Signal Trigger Observe the video circuit of a television, apply the video trigger and obtain the stable video output signal display. Video Field Trigger For the trigger in the video field, carry out operations according to the following steps: (1) Push the Trigger Menu button to display the right menu. (2) In the right menu, select Type as Single. (3) In the right menu, select Single as Video. (4) In the right menu, select Source as CH1. (5) In the right menu, select Modu as NTSC.
7. Troubleshooting 1. Oscilloscope is powered on but no Display. Check whether the power connection is connected properly. Restart the instrument after completing the checks above. If the problem persists, please contact PEAKTECH and we will be under your service. 2. After acquiring the signal, the waveform of the signal is not displayed in the screen. Check whether the probe is properly connected to the signal connecting wire.
