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.

waveform, you simply fill in the blanks to

describe the waveform.

Figure 8. 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.
