The Auto Set-up Function
Function
The auto set-up function automatically sets each key setting, such as the V/div, T/div and
trigger level, to the optimum value for the input signal.
Center position after auto set-up
0V
: Sets the center position to “0 V”. Convenient when you want to see the relation
between the ground level and the waveform.
offset : Sets the center position to the offset value. Convenient when you want to see the
waveform with maximum amplitude.
An example of auto set-up: The following screens show the square waveform with an offset of
1 V and an amplitude of 500 mVp-p after auto set-up.
Auto set-up (0 V)
Auto set-up (offset)
Setting channel(s)
CH1 to CH16 : Auto set-up is performed only for the selected channel. Select the channel
using one of the keys CH1 to CH16. However, if auto set-up is performed on a
channel which has a temperature module or a logic input module installed, an
error message is displayed.
ALL
: Auto set-up is performed for all channels. However, channels which have
temperature modules or logic input modules installed are excluded from the
auto set-up.
Canceling auto set-up
To cancel auto set-up, just press the “
Undo
” soft key. This will restore the previous state
which was in effect before the auto set-up.
Waveforms for which auto set-up is effective
Frequency : Approx. 50 Hz to 100 kHz
Amplitude : Approx. 100 mVp-p or higher when the probe attenuation is 10:1.
Type
: Repetitive (but not complex) waveform
Where input coupling is DC.
Note
The auto set-up function may not operate correctly in certain cases such as when the waveform contains DC
components or high frequency components.
