2.2 Using Autoset
The 2540B/2542B/2540B-GEN/2542B-GEN oscilloscopes
provide an Autoset function which sets the vertical, horizontal,
and trigger controls automatically for optimal display of the
signal(s) connected at either or both CH1 and CH2.
Autoset function detects, turns on, and scales any channel
with a repetitive waveform if it meets the following
requirements:
•
Frequency of at least 50Hz
•
Duty cycle greater than 0.5%
•
Amplitude of at least 10 mVpp
Note: Any channels that do not meet these requirements
are turned off.
When you are using more than one channel, the Autoset
function sets the vertical controls for each channel and uses
CH1 to set the horizontal and trigger controls.
To configure the oscilloscope quickly and automatically to
see connected signals, press the AUTO key. The
oscilloscope will take a few seconds to automatically set
