Features at a Glance
The Keysight N6705 DC Power Analyzer is a multi-functional power system that combines the
functions of a multiple-output DC voltage source with the waveform/data capturing capability of an
oscilloscope and data logger.
As a multiple-output DC source, the Keysight N6705 provides up to four configurable outputs.
Available power modules have power levels of 20 W through 500 W, have various voltage and current
combinations, and provide a variety of performance features as described under Model Differences.
Each output also has arbitrary (Arb) waveform generation capability, which lets you program
predefined voltage and current waveforms – or define your own waveforms. Keysight N678xA
Source/Measure Units (SMU) have a multiple-quadrant power mesh with separate voltage and
current priority source modes.
As a measurement system, the Keysight N6705 displays the average output voltage and current in
Meter View. Waveforms are displayed in Scope View, which you can adjust using vertical and
horizontal controls. The Data Logger View measures and charts average and peak voltage and
current measurements over an extended period.
Source Features
lColor-coded display and output controls - Full programming capability is provided for the entire
range of output voltage and current. Outputs can operate as either constant voltage (CV) or con-
stant current (CC) sources.
lProgrammable voltage and current - Full programming capability is provided for the entire range
of output voltage and current for all power modules.
lLow Output Noise - Available on Keysight N676xA and N675xA power modules. Output noise is
