5550–33300 VA CSW Series
from the front panel where clearly laid out menu’s
guide the user through the transient definition
process.
The front panel provides a convenient listing
of the programmed transient sequence and
allows for transient execution Start, Stop, Abort
and Resume operations. User defined transient
sequences can be saved to non-volatile memory
for instant recall and execution at a later time.
The included Graphical User Interface program
supports transient definitions using a spreadsheet-
like data entry grid. A library of frequently used
transient programs can be created on disk using
this GUI program.
Harmonic Analysis
The CSW Series provides detailed amplitude
and phase information on up to 50 harmonics
of the fundamental voltage and current (up to
16 kHz). 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.
Waveform Acquisition
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.

Multi-Box Option
In many applications high power is required for
a small portion of the testing while a majority of
the tests are performed at reduced power levels.
The controller architecture of the CSW provides
the end-user with a wide array of configuration
options that often eliminate the need to purchase
different AC or DC power systems to meet a
variety of applications. The Multi-Box option is
available which allows multiple channel systems
to be separated into individually controlled stand
alone power sources. By simply connecting the
interface cable between multiple sources the
hardware automatically sets itself to the system
configuration offering Plug and Play performance.
There is no need to modify configuration settings
from the front panel or hardware jumpers located
internally to the source. The multi-box feature
is ideal for end-users planning to increase power
levels or separate a system into multiple smaller
sources.
