Fluke PM3370B user manual Magnify Horizontal, Function of the timebase magnifier and X POS control

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.
