Format YT, XY
YT format displays the vertical voltage in
relation to time (horizontal scale)
XY format disp
lays a dot each time a sample
is acquired on channel 1 and channel 2
Channel 1 v oltage or current determines the
X coordinate
of the dot (horizontal) and the
channel 2 voltage or current determines the
Y coordinate (vertical)
Brightness Makes it easier to distinguish a channel
waveform from persistence
Brightnes
s controls the intensity of the
display backlight. Adjust the brightness with
the multipurpose knob.
Depending on the type, waveforms will be displayed in three different styles:
solid, di
mmed, and broken.
1. Asoli
d waveform indicates a channel (live) waveform display. The waveform
remains solid when the acquisition is s topped if no controls are changed that
make the display accuracy uncertain.
Changing the vertical and horizontal controls is allowed on stopped
acquisitions.
2. Reference waveforms appear white and waveforms with pers istence applie d
appear in the same color as the Main waveform, but with less intensity.
3. A broken line indicates the waveform display no longer matches the controls.
This happens when you stop the acquisition, and change a control setting that
the oscilloscope is not able to apply to the displayed waveform. For example,
changing the trigger controls on a stopped acquisition causes a broken-line
waveform.
