Icon definitions
1.
Represents the signal frequency currently selected
as trigger source.
2.
Represents the triggering point of the current
waveform.
3.
Represents the trigger level of the current waveform.
4.
Distance between the triggering position and the
horizontal centre point.
5.
The time base value of the main time base M1
i.e SEC/DIV
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 increase and decrease
the selected zone in size by turning the
horizontal SEC/DIV 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).
