Icon definitions
1.
Represents the memory position of the current waveform.
2.
Represents the memory position of the triggering point.
3.
Represents the position of the triggering point in the current waveform window.
4.
Horizontal time base (main time base) ie: sec/div.
5.
Horizontal distance between the triggering position and the window centre point.
Definitions
•
YT Mode: in this mode the y axis indicates voltage and the x axis indicates time.
•
X-Y Mode: in this mode the X axis indicates CH1 voltage and the Y axis indicates
the CH2 voltage.
•
Slow Scanning Mode: When the horizontal time base control is set at 50ms/div or
slower, the unit will operate in the slow scan sampling mode. When observing low
frequency signals in slow scanning mode, it is advised to set the channel coupling
as DC.
•
Sec/Div: a horizontal scaling (time base) unit. If waveform sampling is stopped (by
pressing the RUN/STOP button) time base control can expand or compress the
waveform.
Window Extension
•
Window extension can be use to zoom in or zoom out a band of waveform to check
image details. The window extension setting must not be slower than that of the
main time base.
•
In the time base extension mode, the display is divided into two zones as shown.
•
The upper part displays the original
waveform. You can move this zone left or
right by turning the horizontal POSITION
control, or increase and decrease the
selected zone in size by turning the
horizontal SCALE control.
•
The lower part is the horizontally extended
waveform zone.
•
Please note that the resolution of extended
time base relative to the main time base is now higher as shown.
•
Since the waveform shown in the entire lower part corresponds to the selected
zone in the upper part, you can increase the extended time base by turning the
horizontal SCALE control to decrease the size of the selected zone (increase the
multiple of waveform extension).
XY Mode
•
This mode is suitable for CH1 and CH2
only. After selecting the X-Y display mode,
the horizontal axis will display CH1 voltage,
while the vertical axis will display CH2
voltage.
Note: in the normal X-Y mode the oscilloscope
can cause the random sampling rate to acquire
waveforms. To adjust sampling rate and channel
vertical range in the X-Y mode, the omitted
sampling rate is 100MS/s.
