Horizontal Control
Reference
You also can select Delayed Runs After Main or Delayed Triggerable. For
more information on how to use these two menu items, see
Delayed Trigger-
ing
on page 3-22.
Trigger PositionTo define how much of the record will be pretrigger and how much posttrigger
information using the Trigger Position menu item:
Press HORIZONTAL MENU ➞ Trigger Position (main) ➞ Set to 10%, Set
to 50%, or Set to 90% (side), or use the general purpose knob or the keypad
to change the value.
Record Length and Fit To ScreenTo set the waveform record length, press HORIZONTAL MENU ➞ Record
Length (main). The side menu lists various discrete record length choices.
NOTE
If you selected the longest record length available in the Horizontal
menu, then you cannot select Hi Res as your acquisition mode. This
is because Hi Res mode uses twice the acquisition memory that the
other acquisition modes use. If Hi Res and the longest horizontal
record length were allowed to be selected at the same time, the
oscilloscope would run out of memory.
To fit an acquired waveform to the visible screen, regardless of record length,
press HORIZONTAL MENU ➞ Record Length (main). Then toggle Fit to
Screen to ON from the side menu. This provides similar functionality to being
in zoom mode and changing the time/division until the waveform fits the
screen. To turn off this feature, toggle Fit to Screen to OFF.
Horizontal ScaleTo change the horizontal scale (time per division) numerically in the menu
instead of using the Horizontal SCALE knob:
Press HORIZONTAL MENU ➞ Horiz Scale (main) ➞ Main Scale or
Delayed Scale (side), and use the keypad or the general purpose knob to
change the scale values.
Horizontal PositionYou can set the horizontal position to specific values in the menu instead of
using the Horizontal POSITION knob.
Press HORIZONTAL MENU ➞ Horiz Pos (main) ➞ Set to 10%, Set to 50%
or Set to 90% (side) to choose how much of the waveform will be displayed
to the left of the display center.
