Following chapter will offer more details about
the operation mentioned above
UTD1000L Series is designed with autoset
function that can automatically adjust the vertical
scale, scan timebase and trigger mode based o
n
the input signal until the optimal waveform can be
obtained. To apply the autoset function, the tested
signal should have a frequency at 20Hz and
duty cycle 1
Under AUTOSET mode, t
h
ecouplingmodeof
the channel is closely connected to DC autoset
When DC autset is set to off all signals in the
channel is AC coupled If DC autoset is on, the
channel will choose the current setting as coupling
mode, when the current setting is DC coupling, the
signal will be DC-coupled and vice versa
.
For example:
1. Input 1kHz 2Vpp sine signal into two
channels set coupling mode for both channels
to DC press Shift+UTILITY and then F3 to set
UTD1000L User M anua l
Figure 4-8 Adjust Trigger Level
UTD1000L User M anua l
set DC autoset to off. If AUTOSET is applied, the
coup ling m ode is swit che d to AC mo de
.
2. Input 1kHz 2Vpp sine signal into two
channels then set AC coupling for one channel
and DC mode to the other When AUTOSET is
applied the coupling modes for both channels
keep unchanged
UTD1000L can offer creative auto function to
capture input signal With this function applied
,
the Oscilloscope varies ranges accordingly based
on the input signal until the p roper waveform
display can be obtained without any manual
interference
.
To perform autoset function, do the followin
g
1. Press SHIFT button, the shift icon shows o
n
upper right corner of the scree
n
2. Press AUTO button when A icon displays o
n
the screen, autoset function has already turned o

When the model is UTD1000DL and both of
its two channels have signals, the signal from the
trigger source channel will be automaticall

displayed and the other channel will turn off
under autoset mode if there is only one
channel input with signals this channel signal
will be automatically selected and displayed no
matter w hich channel has been choosen as the
trigger source

Autoset for Signals with DC Offset
UTD1000L Series is designed with powerful
autoset function that makes it possible to
perform fast and accurate measurement in D
C
coupled mode for signals with any DC component
.
Position parameter on upper right display of
screen: This parameter stands for position readout
for the channel reference marker that moves from
horizontal central line, if it is positive value, it
indicates the channel marker is above the
horizontal central line and the negative one is for
the marker below the horizontal central line. To
work out the final DC offset, first move the
waveform to the center of the screen, then multipl

For example
:
Connect UTD1000CL channel with 70mVpp A

sine signal mixed with 1.1V DC offset set the
channel to DC coupling, then perform AUTO
function the waveform in Figure 4 24A will
show on the screen. On the display, Positio
n
readout 53.63div indicates the channel
reference marker moves 53.63div downward from
the ho rizon tal ce ntr al line The cu rre nt
amplitude range is 20mV/div so DC offset
readout 20mV/div 53.63div =1.0726V
Vpp readout: 72mV means the AC peak to

with the main timebase, the expanded timebase
has improved the resolution for the waveform

the start and finish amplitude are different, and
high-frequency transient interruption will happen at
