Basic Operation
SINGLE SEQ: Acquire a single waveform and then stop the acquisition.
RUN/STOP: Continuously acquire waveforms or stop the acquisition.
HELP: Display the Help menu.
DEFAULT SETUP: Recall the factory setup. Refer to the following table for relative content.
Save to USB Disk: Save all displays on the screen to a USB device, just like the screen
capturing function of a computer.
5.6.1AUTOSET
Autoset is one of the advantages digital oscilloscopes have. When you push the AUTOSET
button, the oscilloscope will identify the type of waveform (sine or square wave) and adjust
controls according to input signals so that it can accurately display the waveform of the input
signal.
Functions Settings
Acquire Mode Adjusted to Normal or Peak Detect
Cursor Off
Display Format Set to YT
Display Type Set to Vectors for an FFT spectrum; otherwise, unchanged
Horizontal Position Adjusted
SEC/DIV Adjusted
Trigger Coupling Adjusted to DC, Noise Reject or HF Reject
Trigger Holdoff Minimum
Trigger Level Set to 50%
Trigger Mode Auto
Trigger Source Adjusted; Autoset can not be used for the EXT TRIG signal
Trigger Slope Adjusted
Trigger Type Edge
Trigger Video Sync Adjusted
Trigger Video Standard Adjusted
Vertical Bandwidth Full
Vertical Coupling DC (if GND was chosen before); AC for the video signal; otherwise,
unchanged
VOLTS/DIV Adjusted
The Autoset function examines all channels for signals and displays corresponding waveforms.
Autoset determines the trigger source according to the following conditions.
If multiply channels get signals, the oscilloscope will use the channel with the lowest
frequency signal as the trigger source.
If no signals are found, the oscilloscope will use the lowest-numbered channel displayed
in Autoset as the trigger source.
