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. Check the Accessories

The supplied acc essori es have b een al read y des crib ed in t he "Appendix A: Enclosure" of this Manual. You ca n check whether t here is an y loss of acc essories w ith r eferenc e to this description. If it is found that there is any accessory lost or damaged, please get in touch with our distributor responsible for this service or our local offices.

3. Check the Complete Instrument

If it is found that there is damage to the appearance of the instrument, or the instrument can not work normally, or fails in the performance test, please get in touch with our distributor responsible for this business or our local offices. If there is damage to the instrument caused by the transportation, please keep the package.

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. For adjusting the probe compensation, please carry out the following steps:

1. Set the attenuation coefficient of the probe on th e menu as 10X and that of the

switch in the probe as 10X (see "How to Set the Probe Attenuation Coefficient" on P12), and connect the probe with the CH1 channel. If a probe hook tip is used, ensure that it keeps in close touch with the probe. C onnect the probe tip with the signal connecto r of the prob e compensator and connect the reference wire clamp with the ground wire connector of the probe connector, and then push the Autoset button on the front panel.

2. Check the displayed waveforms and regulate the probe till a correct

compensation is achieved (see Figure 3-6 and Figure 3-7).

oscilloscope.

The set values of the probe switch are 1X and 10X (see Figure 3-8).

Figure 3-8 Attenuation Switch

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.

3.Junior User Guidebook

connect the probe to the

Identify the Probe Attenuation C oe fficient Au tomatically

The oscilloscope can identify the probe attenuation coefficient of the 100:1 (impedance 5K±20%) or 10:1 (impedance 10K±20%) probe with the identifying pin. When you attach the probe, the oscilloscope set the attenuation automatically on the oscilloscope vertical menu for the channel to match the probe.

For example, if you attach a 10:1 probe with the identifying pin, the screen will prompt "The probe attenuation factor is X10", and set the attenuation to 10X automatically on the oscilloscope vertical menu for the channel.

How to Use the Probe Safely

The safety guard ring around the probe bod y protects your finger against any electric shock, shown as Figure 3-9.

Figure 3-9 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.

Before making any measurements, always instrument and connect the ground terminal to the earth.

How to Implement Self-calibration

The self-calibration application can make the oscilloscope reach the optimum condition rapidly to obtain the most accurate measurement value. You can carry out this application program at any time. This program must be executed whenever the change of ambient temperature is 5℃ or over.

Before performing a self-calibration, disconnect all probes or wires from the input connector. Push the Utility button, select Function in the bottom menu, select Adjust. in the left menu, select Self Cal in the bottom menu; run the program after everything is ready.

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 8192 data points of the time-domain signal into its frequency components mathematically (the record length should be 10K or above). The final frequency contains 4096 points ranging from 0Hz to Nyquist frequency.

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

1. Press the Math button to display the math menu in the bottom.

2. Select FFT in the bottom menu.

3. In the right menu, select Source as CH1.

4. In the right menu, select Window. In the left menu, turn the M knob to select the

proper window type.

5. In the right menu, select Format. In the left menu, turn the M knob to select amplitude unit (V RMS, Decibels) or phase unit (Radian, Degrees).

6. Select Hori (Hz) in the r ight menu; select repeatedly to make the symbol in front

of the horizontal position value (the upper one), turn the M knob to adjust the horizontal position of FFT waveform; then select to make the symbol in front of the time base value below, turn the M knob to adjust the time base of FFT waveform.

7. Select Vertical in the right menu; do the same operations as above to set the vertical

position and vertical division.

To select the FFT window

■ Th ere are 6 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.

Kaiser

The Kaiser window is best used when frequencies are very close to the same value but have widely differing amplitudes (the side lobe level and shape factor are closest to the traditional Gaussian RBW ). This window is also good for random signals.

The Bartlett window is a slightly narrower variant

Bartlett

of the triangular window, with zero weight at both ends.

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.

4.Advanced User Guidebook

 DC component or offset can cause incorre ct 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.

What is Nyquist freque nc y?

The Nyquist frequ ency is the highes t frequency that any real-time digitizing oscilloscope can acquire without aliasing. This frequency is half of the 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.

Use Vertical Position and Scale Knobs

The 4 channels use the same Vertical Position and Ver tical Scale knobs. If you want to set the vertical scale and vertical position of a channel, press CH1, CH2, CH3 or CH4 at first to select the desired channel. Then turn the Vertical Position and Vertical Scale knobs to set the values.

1. The Vertical Position knob is used to adjust the vertical positions of the selected

waveforms. The analytic resolution of this control knob changes with the vertical division. When the Vertical Position knob is rotated, the pointer of the earth datum point of the selected channel is directed to move up and down following the waveform, and the position message at the center of the screen would change accordingly (see Figure 4-1).

2. The Vertical Scale knob is used to regulate the vertical resolution of the selected

wave forms. The sensitivity of the vertical division steps as 1-2-5. The vertical scale is displayed at the left bottom corner of the screen (see Figure 4-1).

How to Set the Trigger/Decoding System

Trigger determines when DSO starts to acquire data and displa y wav efo rm . On ce trigger is set correctly, it can convert the unstable display to meaningful waveform. When DSO starts to acquire data, it will collect enough data to draw waveform on left of trigger point. DSO continues to acquire data 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. Trigger control area consists of 1 knob and 2 menu buttons. Trigger Level: The knob that set the trigger level; push the knob and the level

will be set as the vertical mid point values of the amplit ude of the trigger signal.
