SVAN 948 USER MANUAL

4 - 16

If in each channel a selected result is saved, in order to view time history in all channels the user

has to press the

and

push-buttons.

The displays in the PLOT presentation mode; the change of the profile and channels

In the

PLOT

it is possible to shift the horizontal axis in relation to the vertical one using the

<SHIFT>

with

<SHIFT>

with

push-buttons. Each pressing of the

<SHIFT>

and

push-buttons

results in 10 dB shifting down of the presentation and each pressing of the

<SHIFT>

and

push-

buttons - 10 dB shifting up.

The view of the displays in the PLOT presentation mode with the shifted axes

Notice: In the buffer many time histories can be stored

, registered during the

measurements. The user can select for the presentation the required time history in the

BUFFER VIEW

window available in the

DISPLAY

list (see Chapter 5 for details).
