UTD1000L Series is designed with autoset

function that can automatically adjust the vertical

scale, scan timebase and trigger mode based on

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, th

e coupling mode of

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
