TIMEBASE MAGNIFY

The displayed signal can be expanded horizontally so that more

signal detail becomes visible. In the analog mode, a *10

magnification is possible and the entire sweep length can be made

visible by turning the X POS control.

- Press the right MAGNIFY key.

The text ’MGN’ appears in the bottom of the screen to indicate that the function is

active. Observe that the timebase indication is changed from 1.00 ms/div to

100 µs/div.

- Press the ANALOG key to set the scope in the digital mode.

- Press the right MAGNIFY key.

Observe that the signal expands in *1, *2, *4 ... steps to a maximum of 32 times.

This magnification factor is displayed briefly on the screen.

- Set the MAGNIFY to *4.
