Advanced Measurement Features
Offer More Design Insights
The N6781A and N6782A 2-quadrant
SMUs offer advanced sourcing and
measurement capabilities required to
overcome test challenges associated
with optimizing power consumption
and maximizing battery life of
battery-powered devices and their
components.
The N6784A 4-quadrant
SMU offers
advanced sourcing and measurement
capabilities in all four quadrants. It
is designed to be a versatile tool for
general purpose applications.
Seamless Dynamic Measurements
(N6781A and N6782A only)
Seamless measurement ranging
eliminates the challenges of measur-
ing dynamic currents. With seamless
measurement ranging, engineers can
precisely measure dynamic currents
without any glitches or disruptions
to the measurement. As the current
drawn by the DUT changes, the SMU
automatically and instantaneously
detects which current measurement
range will return the most precise
measurement and changes to that
range seamlessly. When combined
with the SMU’s built-in 18-bit
digitizer, seamless measurement
ranging enables unprecedented
effective vertical resolution of
approximately 28-bits. This pro-
vides unrivaled productivity gains
