(9)Magniﬁed signal display (MAG)

In storage mode there are two ways of

expanding a speciﬁc signal waveform or dis-

playing it in expanded form. The ﬁrst way is

to pull out the VARIABLE knob (24), the other

is to use the TIME/DIV switch in conjunction

with the HOLD function.

a) Expansion using Variable switch (24)

The signal or signal spectrum can be ex-

panded by a factor of 10 ("stretched") in storage

mode by pulling out the VARIABLE knob (24).

b) Expansion using the HOLD button and the

TIME/DIV switch

In storage mode, press the HOLD button to

freeze the screen content that is to be ex-

panded. Turn the TIME/DIV knob (21) clock-

wise (to the right) one switch position further.

This displays the signal magniﬁed by a factor

of "2". Turning the switch another step to

the right stretches the expanded signal again

by a factor of "2". Each further turn of the

switch to the right expands the waveform by

a factor of "2.5", i.e. a total factor of "10" (2

x 2 x 2.5 = 10) => three switch positions.

Example:

You can read off the individual division factors

by watching the dT screen overlay at the top

edge of the screen.

Basic setting: 10.72 µs/div, one switch position

(the first), subsequent switch position: 5.36

µs/div.

One switch position further (the second): 2.68

µs/div. Finally, the third switch position to the

right: 1.072 µs/div --> 1/10th.

If you turn the TIME/DIV switch further or turn it

in the wrong direction (to the left), no further

sweep expansion takes place.

(10) Interpolation

If expanding a signal waveform distorts the

way in which it displays, the signal can be

"smoothed" or modiﬁed by interpolation (see

also Figure 14).

The "INTERPOLATION" sub-function is selected

by pressing the "MENU" button. Keep this but-

ton pressed until "ITPL OFF" appears at the top

edge of the screen in the middle. Then use the

"SELECT" button (underneath it) to set linear

interpolation "ITPL LIN" or sine interpolation

"ITPL SIN " or "interpolation off" ("ITPL OFF").

Note

Signals that have been stored in the recor-

ding memory cannot be expanded.

If both channels (1 and 2) are operating, both

channels (CH 1 and CH 2) are expanded by a fac-

tor of 10. When the knob is pushed in again, the

non-expanded signal waveform appears

again.eint erneut der ungedehnte Signalverlauf.
