The Agilent N6700 Modular Power System – At a Glance
The Agilent N6700 Modular Power System is a configurable, one rack-
unit (1U) platform that lets you mix and match power modules to
create a power system optimized for your test system requirements.
Agilent N6700–N6702 MPS mainframes are available in power levels
of 400 W, 600 W, and 1,200 W. Up to four power modules can be
installed in each mainframe. Power modules come in power levels of
20 W through 500 W, have various voltage and current combinations,
and provide the following performance features:
 The N673xB, N674xB, and N677xA DC Power Modules provide
programmable voltage and current, measurement, and protection
features, making these economical models suitable for powering
the device-under-test or system resources such as fixture controls.
 The N675xA High-Performance, Autoranging DC Power Modules
provide low noise, high accuracy, fast programming times, and
advanced programming and measurement capabilities to speed
test throughput.
 The N676xA Precision DC Power Modules provide precise control
and measurements in the milli- and micro-ampere region with
the ability to simultaneously digitize voltage and current and
capture those measurements into an oscilloscope-like data buffer.
 The N678xA Source/Measure Units (SMU) have a multiple-
quadrant power mesh with separate voltage and current priority
source modes. These models are optimized for applications such
as battery drain analysis and functional testing.
 The N6783A Application-Specific DC Power Modules are two-
quadrant low-wattage models specifically designed for battery
charging/discharging and mobile communications applications.
The output and system features are described in the following
sections. Not all output features are available on every power
module. The “Model Differences” section describes the features that
apply only to specific power modules.
Output Features
Programmable voltage
and current
Full programming capability is provided for the entire range of output
voltage and current. Outputs can operate as either constant volt
age (CV) or
constant current (CC) sources.
Low output noise
Available on Agilent N676xA and N675xA power modules. Output noise is
<4.5 mV peak-to-peak, which is comparable to linear supplies.
Fast up/down
programming
Available on Agilent N675xA, N676xA,
and N678xA SMU power modules.
≤1.5 millisecond response time from 10% to 90% of the output rating.
Fast transient response
Available on Agilent N675xA, N676xA, and N678xA
SMU power modules.
Transient response is less than 100 μs.
