Measurement and Analysis
The i/iX Series II is much more than a
programmable AC and DC power source. It also
incorporates an advanced digital signal processor
based data acquisition system that continuously
monitors all AC source and load parameters.
This data acquisition system forms the basis for
all measurement and analysis functions. These
functions are accessible from the front panel and
the remote control interface.
i/iX Series II
Waveform Acquisition [iX Series II only]
The measurement system is based on real-time
digitization of the voltage and current waveforms
using a 4K deep sample buffer. This time domain
information provides detailed information on
both voltage and current waveshapes. Waveform
acquisitions can be triggered at a specific phase
angle or from a transient program to allow
precise positioning of the captured waveform
with respect to the AC source output.
The front panel LCD displays captured waveforms
with cursor readouts. The included GUI program
also allows acquired waveform data to be
displayed, printed and saved to disk.
Measurement data for single phase (iX Display).
Measurement data for all three phases (iX Display).
Harmonic Analysis [iX Series II only]
The iX Series II provides detailed amplitude and
phase information on up to 50 harmonics of
the fundamental voltage and current for either
one or three phases. Harmonic content can be
displayed in both tabular and graphical formats
on the front panel LCD for immediate feedback
to the operator. Alternatively, the included GUI
program can be used to display, print and save
harmonic measurement data. Total harmonic
distortion of both voltage and current is
calculated from the harmonic data.

with cursor positioned at the fundamental (iX Display).
