Common Operations
Explanation
The auto setup function automatically sets the key settings such as V/div, T/div, and
trigger level that are appropriate for the input signal.
Before auto setup After auto setup
Center Position after Auto Setup
The center position after auto setup is 0 V.
Applicable Channels
Auto setup is performed on all channels.
Loaded Waveforms
When auto setup is executed, loaded waveforms are unloaded (cannot be recovered
using the Undo Auto Setup soft key).
Canceling Auto Setup
Pressing the Undo Auto Setup soft key sets the DL7400 back to the settings that existed
immediately before auto setup. However, when you turn OFF the power switch, the
settings that existed immediately before auto setup are cleared. Therefore, the “Undo”
operation is not possible in this case.
Applicable Waveforms for Auto Setup
Frequency Approx. 50 Hz or higher
Absolute value of the Maximum value is greater than or equal to approximately 20 mV (1:1)
input voltage
Type Repetitive waveform (that is not complex)
Note
The auto setup function may not work properly if the waveform includes DC components or
high-frequency components.
