5 - 44 FUNCTION REFERENCE
MAGNIFY HORIZONTAL
Description:
In the
analog
mode, the MAGNIFY key pair switches between the normal trace
and horizontal expansion of the trace by a factor of 10. The maximum timebase
speed is then increased from 20 ns/div to 2 ns/div.
In the
digital
mode, the same MAGNIFY key pair gives horizontal expansion of
x1, x2, x4 up to 32 times for detailed viewing of captured signals. This results in
an expansion of the timebase range from 2 ns/div to 62.5 ps/div. The MAGNIFY
keys also allow horizontal compression of up to 32 times so that full records of 8K
(32K optional) can be displayed on a single screen without loss of information.
The current magnification factor is temporarily displayed on the screen when you
are making a change. When the magnify function is active, the magnification
factor is permanently displayed on the screen.
In both analog and digital modes, the X POS control positions the trace with respect
to the screen to display the part of interest. When you adjust X POS, a bargraph is
temporarily displayed to show which part of the trace is currently being displayed.
