Trigger status identification: include TRIGED , AUTO, READY, STOP,
and ROLL
②.
Indicates the amount of time represented by one square, which can be
adjusted by the horizontal scale knob.
③
. Shows the horizontal displacement, which can be adjusted by turning
the horizontal position knob.
④
. Displays trigger source, type, slope, coupling, level, etc.
a
.
Trigger Source: they are CH1, CH2, AC Line, EXT,etc.
b Trigger types : edge, pulse width, video, slope, etc.
.
c Trigger slope: rising, falling, and rising/falling. For example, is rising.
.
d Trigger coupling: DC, AC, high frequency, low frequency and noise.
.
For example, is DC coupling.
⑤
. Hardware frequency meter: display the frequency information of current
channel.
⑥
. USB device Identification : This icon will be displayed when an USB
storage device is connected.
⑦
. Channel vertical status Identification: Displays channel activation state,
channel coupling, bandwidth limit, vertical profile, and probe attenuation
coefficient.
⑧
. Sampling Rate/Acquisition Mode: Indicates the current sampling rate
and storage depth.
Chapter 2 -Vertical Channel Setting
2.1 Open / activate / close analog channel
CH1~CH2 contains 3 states: open, activate, and shut down.
Open: Allows the corresponding channel waveform to be displayed on the
screen.
Activate: Only opened state can be activated. In the active state
，
the vertical
menu and the vertical control knobs (POSITION, SCALE) are available for
changing activated channel setting. Any of the channels that has been opened
but not been activated could be activated by perssing the corresponding
channel keys
Shut down : No waveform appears on the display.
The table below describes the channel menu:
Description
Pass AC and DC components of the input signal
Pass AC part of input signal only
Displays ground signal
Turns off bandwidth limit function
Limits bandwidth to 20MHz to reduce the noise.
The vertical sensitivity of the current
channel can be set to 1, 2, and 5 order.
Set Fine Adjustment to be within the coarse
range. Set the channel’s vertical sensitivity
with 1% of the current amplitude value.
A value is automatically selected according
to the probe’s attenuation coefficient, to
ensure consistency between the vertical
profile readout and the displayed waveform.
