MX Series - Measurement and Analysis
The MX Series is much more than a
programmable AC, DC or AC+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 for
the MX Series (MX15 excluded; uses 2-line display
shown below).
Conventional Measurements [All controllers]
Common AC and DC measurement parameters
are automatically provided by the data acquisition
system. These values are displayed in numeric
form on the front panel LCD display. The
following measurements are available: Frequency,
Vrms, Irms, Ipk, Crest Factor, Real Power (Watts),
Apparent Power (VA) and Power Factor.
Harmonic Analysis [Pi controller]
The MX Series provides detailed amplitude and
phase information on up to 50 harmonics of
the fundamental voltage and current (up to 16
kHz in three phase mode) 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 (excluding MX15). 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.
Waveform Acquisition [Pi controller]
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 (excluding MX15). The
included GUI program also allows acquired
waveform data to be displayed, printed, and
saved to disk.
