Menu items

Depending on the operating mode (Yt or XY) this menu will offer
various cursor measuring functions which will affect the cursor
lines and their positions.

4.1 Meas.(uring) Type

If this function is activated, the INTENS knob

can be used

for measurement selection. In most cases the corresponding
unit will be automatically displayed. The measuring modes are
self explanatory.

4.2 Unit

In the modes ”Ratio X“ and ”Ratio Y“ the INTENS knob symbol
will be shown in addition to a unit, as it may then be used to
change the unit.

4.2.1

” rat ” (ratio), display of ratios

In this mode the ratios of duty cycles or amplitudes may be
determined with the CURSORS. The distance between the long
CURSOR lines is equal to 1.

4.2.2

” % ” (percent), display of percentages

The distance between the long CURSOR lines is equal to 100%.
The result will be determined by the distance of the short
auxiliary cursor line to the long reference line (lower, left re-
spectively), with a negative sign if appropriate.

4.2.3

” ° ” (degree), measurement of degrees

The distance between the long CURSOR lines is equal to 360
degrees and must be exactly as long as a signal period. The
measurement result will be determined from the distance
between the reference line to the short auxiliary cursor line,
with a negative sign If appropriate. For further information
please consult ”Measurements of phase differences in dual
channel mode (Yt)“ in the section ”First time operation and
pre settings“.

4.2.4

”

One period of a sine wave is equal to 2

, hence the distance

between the two long CURSOR lines must be set to one peri-
od. If the distance between the reference line and the short
CURSOR line equals 1.5 periods, ”3

“ will be displayed. If the

short cursor line is to the left of the reference line a negative
sign will be shown.

4.3 Respect

It may be necessary to determine for which signal channel the
CURSOR measurements are valid. This is done by showing the
INTENS knob signal next to the channel number. After selection
of the signal source, the CURSOR lines must then be positioned
to the signal displayed by this channel.

4.4 Off (Cursors Off)

Pressing the function key “Off” switches the “Cursors” menu,
the cursor lines and the cursor measurement results off.

If only the displayed “Cursors” menu is to be switched off, press
the MENU OFF pushbutton

SAVE/RECALL

(pushbutton)

This pushbutton will open up a menu.

Under SAVE/RECALL the current instrument settings may be
saved or settings saved earlier recalled. There are 9 non volatile
memories available.

5.1 Saving the actual settings

Upon pressing the pushbutton the menu ”Front Panel“ will be
accessed. Pressing the function key “Save” shows one func-
tion key for page selection and numbered memories allocated
to function keys. Pressing a memory function key stores the
current instrument settings in the selected memory location
number .

5.2 Recall the actual settings

The menu ”Front Panel“ will be displayed after pressing the
SAVE/RECALL pushbutton. Pressing the function key “Recall”
shows one function key for page selection and numbered me-
mories allocated to function keys. Pressing a memory function
key causes loading of the stored settings.
