Subject to change without notice

the zoom time base display is shown in white. This means

that the large knob in the horizontal menu is now available

for changing the zoom factor. This knob also features a push

contact; if the knob is pushed, the time base display will change

to white, and the zoom time base display to grey: now the knob

is available for changing the time base setting. This allows you

to change time base settings without leaving the zoom mode.

By pressing the knob again, the cursors limiting the zoom area

will be shown pronounced in white, now the knob will also allow

to change the zoom area. The position of the zoomed area can

now be shifted with the small knob in the horizontal area of the

front panel over the whole signal. If pushing the large knob as

described above would inuence the time base setting and not

the zoom factor, the small knob regains the function of shifting

the trigger position so the relationship of pre to post trigger

record can be changed.
