Term explanation:
Y
-T mode:
X-Y mode:
Y axle refers to voltage and X axle
refers to time quantum under this mode
.
X axle refers to CH1 voltage and Y axle
refers to CH2 voltage under this mode
.
Slow scanning mode: Instrument will enter into
slow scanning sampling mode when settin
g
horizontal time base control to 100ms/div or less. It
is suggested to set channel coupli ng to DC whe
n
observing low-frequency signal by applying for
slow scanning mode
.
s-div: Time base control can expand or compress
waveform for horizontal scale (or time base) unit if
stopping waveform sampling (by using RUN/STOP
key).
