Most importantly, the N1918A Power
Panel software leverages power
measurement data available from the
data outputs of other power meter
instruments like the Agilent P-Series
N1911/12A and Agilent N8262A
meters. Since those meters and
associated peak and average sensors
characterize complex power signals,
including pulsed, spread spectrum and
wireless communications formats, the
optional N1918A-100 Power Analysis
Manager delivers statistical
measurement results with such data
like PDF, CDF, and CCDF.
This application note provides
adequate internal details of the U2000
Series hardware and the N1918A
Power Analysis Manager software
to provide the reader engineer with a
basic understanding of their operation
and performance capabilities. It
outlines a number of suggested
measurement applications to show
typical confi gurations. It also reviews
the basic power measurement theory
about calibration, power traceability
and measurement uncertainties,
using prior references available in
other literatures. Finally, it considers
sensor detection stability with time
and environment, in order to ensure
long-term measurement confi dence
(1 year), even with the sensor being
installed remotely.
