points of storage), users can have the freedom to store as many waveforms of different lengths as
they desired in a dynamic fashion (with the limit of total points not to exceed memory capacity).
Then, by using STORE and RECALL functions to save the starting address and lengths of each
created arbitrary waveforms, users can quickly locate (in the memory) and output each of the
different waves. These functions can behave like reference points, so users can actually save up to
49 different waveform reference points in the memory.
See example illustration below to see how it works:
Stored Buffer number Data points of different waveforms
(Start address + length)
1 A pts.
2 B pts.
3 C pts.
4 D pts.
From the above illustration, all the points of Waveform 1 can be stored and recalled using buffer #1.
Likewise, Waveform 2 can be stored/recalled by buffer #2. Waveform 3 by buffer #3. Waveform 4 by buffer
#4.
F3: POWER - (Power-on default) Selects the power-on default setting. Select a value using the numeric keypad
or the rotary input knob. The selection is effective after a 10 s time-out period. Select zero (0) to
have the waveform generator power on with the factory default settings. Select 50 to have the
waveform generator power-on with the settings it had at the last power-off. Select any other value
in the range from 1 to 49 to have the waveform generator power-on with the settings that you have
saved with F2:STORE(see above) in the range of 1 to 49.
Note: Channel output status can be stored and recalled in memory, but cannot be
recalled for power-on setting. Meaning, at any given time, at power on the channel
output status will always be OFF regardless of what memory block power-on setting is
set to recall at power up. This is a safety feature because if user accidentally turns on
with the outputs on, sometimes it can easily damage a connected device that is sensitive
to signal levels connected to it.
