Each DC power output on the Keysight
N6705 DC power analyzer can be
modulated by the module’s built-in
arbitrary waveform generator. This permits
the output to act as a DC bias transient
generator or power arbitrary waveform
generator. The maximum bandwidth
is based on the type of module that
is installed (basic, high-performance,
precision, and SMU). Refer to the Keysight
N6700 Modular Power System Family
Specifications Guide* for the bandwidth of
each DC power module.
The Keysight N6705 uses run length
encoding, where each point in the
waveform is defined by the voltage setting
and 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.
The Keysight N6705 offers the following
waveform choices (see table below).
For each waveform, you can set it to
repeat continuously or you can specify the
number of times the waveform is repeated.
Arbitrary Waveform Generator
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 user-defined voltage and current
waveforms, you can download up to 512
setpoints of voltage or current. For each
setpoint, a dwell time is specified and
output will stay (i.e., dwell) at that setpoint
for the programmed dwell time value. For
each of the 512 setpoints in the user-de-
fined waveform, you can have a different
dwell time from 0 to 262 seconds with 1
microsecond resolution. The module will
step through the user-defined table of
values, staying at each setpoint for the
programmed dwell time, and then it will
move on to the next point. User-defined
waveforms can be imported from a CSV
file or directly entered from the front panel
of the DC power analyzer.
Constant-dwell voltage or current
waveforms can also be generated, with up
to 64000 programmable points.

source)
Up to 512 points with point-by-point adjustable dwell

for all points)
Figure 8. Once you have selected a
waveform, you simply fill in the blanks to
describe the waveform.
Figure 7. The Arb Selection menu is used to
select which pre-programmed waveform
will be applied to the output of the DC
power module. Each of the four outputs can
have a different waveform applied.
