Arbitrary Waveform Generation
Arbitrary Waveform Sequence 9
Position markers can be set at any or all of the addresses of a waveform either
individually, using the
adrs (address) soft-key, or as a pattern, using the
patterns…
menu.
A marker can be set directly at an address by pressing the
adrs soft-key followed by a
keyboard entry. Pressing the right-hand soft-key on the
adrs line then toggles the
marker setting between
<1> and <0>. The address can be changed by incrementing with
the
adrs key, by using the rotary control, or by further keyboard entries; marker
settings are changed at each new address with the right-hand soft-key. Markers show
immediately they are changed.
Alternatively, markers can be input as patterns by using the
patterns… sub-menu:
PATTERN: 00000000…
start: 00000
stop: 01023
exit: do pattern
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
using the 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 the
POSITION MARKER EDIT
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 16 arbitrary waveforms may be linked in a sequence. Each waveform can have a
loop count of up to 32,768 and the whole sequence can run continuously or be looped up
to 1,048,575 times using the triggered burst mode.
Pressing the
SEQUENCE key calls the initial SEQUENCE screen:
