changed.
Alternatively, markers can be input as patterns by using the

The start and stop addresses of the markers within the waveform are set using the
start
and
stop
soft-keys respectively followed by a direct keyboard entry or by rotary control. The pattern
itself is set in the top line of the display; press the soft-key to the right of
PATTERN:
and enter
the sequence of 1s and 0s using 1 and 0 from the keyboard (which auto-increments to the next
character) or with the rotary control (using the cursor keys to move the edit cursor along the
pattern). The pattern consists of 16 values; if the cursor keys are used to skip over some
character positions these will automatically be filled with the value of the last one specified to the
left. The pattern is entered repeatedly across the whole range defined by the start and stop
addresses when the
do pattern
soft-key is pressed; pressing
exit
returns to
POSITION

screen without implementing the pattern.
Pressing the
clear all
soft-key displays a request for confirmation that all markers should be
cleared from the waveform. Pressing
clear
cancels all the markers and returns the display to
POSITION MARKER EDIT
; pressing
cancel
aborts the clear.
Arbitrary Waveform Sequence
Up to 4 arbitrary waveforms may be linked in a sequence. Each waveform can have a loop count
of up to 32768 and the whole sequence can run continuously or be looped up to 1048575 times
using the Triggered Burst mode.
Pressing the SEQUENCE key calls the initial
SEQUENCE

♦
A previously defined sequence can be run and stopped from this screen using the
run
and
stop
soft-keys; sequence can also be switched on from the
STANDARD WAVEFORMS
screen
with the
sequence
soft-key.
Sequence Set-up
Pressing the
sequence setup…
soft-key on the
SEQUENCE
screen (or the
setup…
soft-key
next to
sequence
on the
STANDARD WAVEFORMS
screen) calls the sequence set up screen:

wfm wv03 limit
◊
◊
step on: count
◊
cnt: 00001 done
◊
Repeated presses of the
seg
soft-key steps the display through the set-ups of each of the 4
segments of the sequence. With the exception of segment 1 which is always on (and therefore
has no on-off soft-key) the 4 segment set-ups are identical in format.
The segment to be set-up is selected with the
seg
soft-key; the 4 segments can be selected in
sequence with repeated presses of the soft-key or by using the rotary control.
