Basic Operation
acquisition mode and displays data as dots. The sampling rate is fixed at 1 MS/s.
The oscilloscope can acquire waveforms in YT format at any sampling rate. You may view the
same waveform in XY format. To perform this operation, stop the acquisition and change the
display format to XY.
The table below shows how to operate some controls in XY format.
Controls Usable or not in XY format
CH1 VOLTS/DIV and VERTICAL POSITION controls Set the horizontal scale and position
CH2 VOLTS/DIV and VERTICAL POSITION controls Continuously set the vertical scale and
position
Reference or Math Unusable
Cursors Unusable
Autoset (display format reset to YT) Unusable
Time base controls Unusable
Trigger controls Unusable
5.2 Horizontal Controls
Use the horizontal controls to change the horizontal scale and position of waveforms. The
horizontal position readout shows the time represented by the center of the screen, using the
trigger time as zero. When you change the horizontal scale, the waveform will expand or contract
to the screen center. The readout near the upper right of the screen shows the current horizontal
position in second. M represents ‘Main Time Base’, and W indicates ‘Window Time Base’. The
oscilloscope also has an arrow icon at the top of the graticule to indicate the horizontal position.
1. HORIZONTAL POSITION Knob: Used to control the trigger position against the screen center.
Push this button to reset the trigger point back to the screen center.
AN: Used to set the horizontal position as zero.
2. Each option in HORIZ MENU is described as follows.
