Getting Started Manual
Arbitrary Waveforms
Arbitrary waveforms are stored in the instrument's internal
memory as a series of values from -2048 to +2047. These
limits correspond to the peak to peak output voltage
range. The points are equally spaced along the time axis
and the number of points defined can be anything from
two (which is the special case of a square wave) to
65,536.
Waveforms can be defined using many different methods,
of which the easiest is to use is a suitable waveform
synthesis program on a PC and the RS232 or GPIB
remote control interface, but they can also be defined,
edited, copied and pasted using the front-panel controls.
The internal RAM can hold up to 100 waveforms which are
accessed by name. Names can have up to eight
characters. The instrument allocates default names
beginning with wv00 and proceeding up to wv99; you
can change these names as you wish.
In this exercise we will create a simple waveform as
shown below:

The waveform has 6 segments numbered 1 to 6 over a
period of 100 µs. The segments start and end at multiples
of 10 µs.
Begin by creating a new, blank waveform:
