Setting the bandwidth limit can reduce the display noise. For example, the signal
under test is a pulse with high frequency oscillation.
 When bandwidth limit is disabled, the high frequency components of the signal

under test can pass the channel.

 Enable bandwidth limit and limit the bandwi dth to 20 MHz or 100 MHz, the high

frequency components of the signal under test that exceed 20 MHz or 100 MHz
are attenuated.

Note: For DS2102E, the bandwidth limit is only 20 MHz.

Vertical Scale

Vertical scale refers to the voltage value per grid in the vertical direction on the
screen and is usually expressed as V/div.

Press CH1  Volts/Div to select the desired adjustment mode of the vertical scale,
or press VERTICAL SCALE to switch the adjustment mode quickly.
 Coarse adjustment: set the vertical scale in 1-2-5 step namely 500 μV/div, 1

mV/div, 2 mV/div, 5 mV/div, 10 mV/div…10 V/div (take cou nterclockwise as an
example).

 Fine adjustment: further adjust the vertical scale at a relat iv e ly smaller step to

improve the vertical resolution. If the amplitude of th e input waveform is a little
bit greater than the full scale under the current scale and the amplitude would
be a little bit lower if the next scale is used, fine adjustment can be used to
improve the amplitude of waveform display to view signal details.

After the adjustment mode is selected, rotate VERTICAL
vertical scale (clockwise to reduce the scale and counterclockwise to increase). The
scale information in the channel status label (as shown in the figure below) at the
bottom of the screen will change accordingly during the adjustment. The adjustable
range of the vertical scale is related to the probe rati o and input im pedance currently

Delay Calibration

When using an oscilloscope for actual measurement, the transmission delay of the
probe cable may bring relatively greater error (zero offset). Zero offset is defined as
the offset of the crossing point of the waveform and trigger level line relative to the
trigger position, as shown in the figure below.

Figure 2-3 Zero Offset

For DS2000E, users can set a delay time to calibrate the zero offset of the
correspondin g channel. Press CH1 Delay-Cal and use to set the desired
delay time. The range available is from -200 ns to 200 ns. Pressing down can
restore the delay time to 0.00 s.

Note: This parameter is related to the instrument model and the current horizontal

time base setting. The larger the horizontal time base is, the larger the setting step
will be. Take DS2202E as an example, when the horizontal time base is 50 ns, the
step is 1 ns; when the horizontal time base is 2 μs, the step is 40 ns; when the
horizontal time base is greater than or equal to 10 μs, the delay calibration time
cannot be adjus t ed.

According to sinθ=A/B or C/D (wherein, θ is the phase deviation angle between
the two channels and the definitions of A, B, C and D are as shown in the figure
above), the phase deviation angle is obtained, that is:

θ=±arcsin (A/B) or ±arcsin (C/D)

If the principal axis of the ellipse is within quadrant I and III, the phase deviation
angle obtained should be within quadrant I an d IV, namely within (0 to π/2) or (3π/2

4. Observe the measurement result shown in the figure above. According to the
measurement schematic diagram of the phase deviation (as shown in Figure

Note:
 The maximum sample rate of X-Y mode is 1.0 GSa/s. Generally, longer sample

waveform can ensure better display effect of Lissajous figure. But due to the
limitation of the memory depth, you have to reduce the waveform sample rate
to acquire longer waveform (refer to the introduction in "Memor y Depth").
Therefore, during the measurement, reducing the sample rate properly can
acquire better display effect of Lissajous figure.

After the system runs, the oscilloscope operates by first filling the pre-trigger buffer.
It starts searching for a trigger after the pre-trigger buffer is filled. While searching
for the trigger, the data sample d will still be transmitted to the pre-trigger buffer (the
new data will continuously ove rwrite the previous date). When a tri gger is found, the
pre-trigger buffer contains the data acquired just before the trigger. Then, the
oscilloscope will fill the post-trigger buffer and display the data in the acquisition
memory. If the acquisition is activated via RUN/STOP, the oscilloscope will repeat
this process; if the acquisition is activated via SINGLE, the oscilloscope will stop
