Clearing an ARB Waveform
Pressing the
PRESET
key of the 3314A while turning on power clears all non-volatile
memory. This includes ARB and non-ARB wavefo
rm
registers. To clear a particular ARB
waveform register, first recall the desired waveform. Then press the BLUE sh
ift
and
ARB keys (equivalent to the
11
AR2" HP
-IB
command). Other ARB waves are not affected.
To clear a waveform, the 3314A deletes vectors one at a time at a rate of about 100
vectors per second, beginning with the next to last vector
.
The cleared waveform is
reduced to two vectors. Then it is initial
ized
to the following default parameters:

• The last vector is the Return to Start Vector

ARB Waveforms and the
If you have numerous or complicated ARB waveforms, you may wish to use a com-
puter proqrarnto build the waveform rather than using the 3314A front panel. At the
end of the REMOTE OPERATION section in this manual, there are examples of ARB
programs. They are written for an -hp- 9000 Series 200/300 computer using the
BASIC 4.0 programming language.
