Toolbar buttons
: Download waveform data to the device.
: Smooth Drawing Mode. You can draw any waveform shape using the left-mouse.
: Line Drawing Mode. You can click on the waveform to draw a straight line from the
previous point.
: Zoom tools. To zoom the time axis in or out, click the + or - zoom button
and then click on the waveform area. Click the 100% button to restore the time axis to
its original scale.
: Standard waveform shapes. Draw a standard waveform
with the settings specified in the numerical controls below the toolbar. The current
waveform will be erased.
: Cycles. The number of cycles to draw. This control is used in
conjunction with the Standard waveform shapes buttons. Select one of the standard
waveform shapes and then enter the number of cycles, and it will draw the requested
number of cycles of the waveform.
: Minimum. When one of the Standard waveform shapes buttons
is pressed, this control sets the minimum signal level.
: Maximum. When one of the Standard waveform shapes
buttons is pressed, this control sets the maximum signal level.
: Duty cycle. When a square, triangular or ramp waveform is
selected using one of the Standard waveform shapes buttons, this control sets the
duty cycle of the signal. Duty cycle is defined as the time that the signal spends above
zero volts divided by the total cycle time. Thus, a symmetrical square or triangular
wave has a duty cycle of 50%. Reducing the duty cycle shortens the positive part of the
cycle and lengthens the negative part, and increasing the duty cycle does the opposite.
Note:
The Frequency, Amplitude, Offset parameter of the ARB waveform can not be
regulated in this WaveEditor software, but it can be done by tuning on the device
directly (refer to above Chapter 3.1) after the waveform data is downloaded to device
(refer to below Chapter 3.3).
Do not use the WaveEditor and the DSO software at the same time, it will cause errors.
