Using the Arbitrary Waveform Generator

Each output on DC Power Analyzer can be modulated by the power
module's built-in arbitrary waveform generator function. This allows
the output to act as a DC bias transient generator or an arbitrary
waveform generator. The maximum bandwidth is based on the type
of power module that is installed. This is documented in the Agilent
N6700 Modular Power System Family Specifications Guide. See the
note in the beginning of Appendix A.
The arbitrary waveform generator has a variable dwell period, where
each point in the waveform is defined by the voltage or current
setting along with the dwell time or duration to stay at that setting.
Waveforms can be generated by specifying only a small number of
points. For example, a pulse would only take three points to define it.
However, sine, ramp, trapezoid, and exponential waveforms have 100
points assigned to the portion of their waveform that continuously
changes. Constant-dwell waveforms can have up to 65,535 points
assigned to them.
Each waveform can be set to repeat continuously or repeat a specific
number of times. For example, to generate a pulse train of 10
identical pulses, you can program the parameters for one pulse and
then specify that you want it to repeat 10 times.
For the user-defined waveforms, you can specify up to 511 step-
points of voltage or current. You can specify a different dwell time for
each of the 511 step-points. The output will step through the user-
defined values, staying at each point for the programmed dwell time,
and then moving on to the next point.
You can also combine a number of individual arbitrary waveforms
into an Arb sequence, as long as the total number of points of all
waveforms does not exceed 511 points.
The following sections provide examples of how to configure a Pulse
Arb, a User-defined Arb, a Constant-dwell Arb, and an Arb Sequence,
which is a combination of Arbs combined in a sequence.
