be subject to vertical calibration (voltage/grid, current/grid). When CF is 6, the
selected voltage range and current range will be subject to two-time vertical
calibration (voltage/grid, current/grid).
Horizontal calibration
When the “KNOB SEL” soft key is pressed and “T/d” is selected, horizontal
calibration (scanning speed) adjusted by rotating the knob. In this case,
time/grid information changes can be observed on the screen by rotating the
knob and changing the horizontal (time/grid) setting. When acquisition is run,
the sampling rate can be changed by adjusting the horizontal calibration knob.
When acquisition is stopped, sampling data can be amplified by adjusting the
horizontal calibration knob.
Trigger delay
When the
KNOB SEL
soft key is pressed and “TD” is selected, the trigger delay
can be adjusted by rotating the knob. In this case, when the knob is rotated, the
trigger point will move horizontally and the delay time will be displayed on the
screen. When the delay time is changed, the trigger point (
) will move
horizontally, and the distance between the trigger point and the horizontal
center will be indicated. The trigger point is displayed along the top of the
display grid.
Trigger waveform
When the specified trigger conditions are satisfied, the trigger waveform will be
displayed, and the triggering time point is called trigger point. The trigger point
is generally displayed in the left of the display screen. Following the trigger point,
the waveform is displayed on the display screen from left to right over time.
Before using the trigger function, the user needs to configure the following
parameters:
Trigger mode
The trigger mode refers to conditions for updating the contents displayed
on the screen. Including the Auto model and Normal mode Auto mode: the
displayed waveform is updated in case of triggering in the pause time and
automatically updated in case of no triggering in the pause time. Normal
mode: the displayed content is updated in case of triggering and not
updated in case of no triggering.
Trigger source
The trigger source is used for generating triggering conditions. The user
can select the trigger source from the input signal of the input unit and the
external clock signal.
Trigger slope
The slope refers to signal changes from low level to high level (rising edge)
or from high level to low level (descending edge). When used as a
triggering condition, the slope is called trigger slope.
Trigger level
Level of trigger slope: triggering occurs when the level of the signal of the
trigger source reaches the set trigger level under the specified trigger slope
conditions. When the “KNOB SEL” soft key is pressed and “TL” is selected,
the trigger level can be adjusted by rotating the knob. In this case, the
trigger level can be changed by rotating the knob, and changes in the
