Powerful Waveshape and Waveform Creation
The SmartWave can easily create fractional or multi-cycle dropouts,
spikes, surges, sags and distorted waveforms from the front panel. To simulate these
complex real-world power occurrences, the SmartWave comes with a library of 50 built-in
waveshapes (see examples on page 11). Users can create and store an additional 50 waveshapes
of their own design.
Output voltages are created by adding amplitude, frequency and other parameters
to the waveshapes. The user can also create over 50 custom front panel setups with all parameters
included and store them for quick recall, making the SmartWave ideal for manual testing.
Sequence Programming
Complex sequence or event programming is easy with time or cycle based transient segments.
The sequence library is made up of a total of 1000 segments stored as labeled sequences.
A sequence of up
to 100 segments using up to 32 different waveshapes, arranged in any
combination, can be run at any one  time.
The 32 waveshapes can be selected from the 50 factory supplied and 50
user created waveshapes. By setting the time or number of cycles for
each segment, the user can create waveform sequences that allow automatic
testing for most any standard.
AC and/or DC
A direct coupled, transformerless design allows AC and DC on separate phases or on the
same phase. The SmartWave can be used as a true DC power supply. High DC content waveforms
(up to 312 volts) can be created with no derating of output power, even with 100% reactive loads.
This can eliminate the need for a separate DC supply.
Graphic LCD Display
The SmartWave has
a graphic LCD display for previewing and confirming the waveforms before
connecting the output to the load. The menus are easy to follow with
the overlay paging format. Users can select menus, slew voltage and
frequency with a handy knob on the front panel. Front panel signal and
sync outputs allow three phase scope viewing.
Powerful DSP2 Waveform Programming
Waveform programming is easily accomplished using the optional DSP PC software.
The software allows freehand creation of waveforms, using a mouse or
mathematical expressions. Real-world waveforms can be uploaded and modified
when using a digital scope. The waveforms can then be downloaded to
the SmartWave via GPIB and output to exactly simulate real-world conditions.
Flexibility in Power Ranges
The SmartWave series
includes the SW 1750 (single phase only), SW 3500 (single or dual phase),
and SW 5250A. The 5250A three phase unit can be switched to single phase
or vice versa, simply by menu selection (and appropriate output wiring
changes). The SW Series is factory upgradable from 1750 VA to 3500 VA
or 5250 VA. Utilizing a master/slave arrangement, SW 5250A can be paralleled
for incrementally higher power requirements, e.g. one master/one slave
= SW 10500 (10.5 kVA). As many as 3 slave chassis may be paralled with
a master to form a 21 kVA system. Options include input power factor
correction, measurement capability, plus 5 and 26 VAC auxiliary outputs.
As shown by this photo, the SmartWave can create time coincident spikes
on 3 phases, fractional or multi-cyle dropouts, sags and surges, waveforms
distortion, DC and noise.
Waveshape Library
There are 50 factory-supplied waveshapes in the SmartWave.
Following are examples of the types of waveshapes in the library:
- Sine wave
- Square wave
- Triangle wave
- Clipped sine waves
- Sine waves with spikes
- Fractional dropouts
- Sine wave with dropout (0V from 0° to 90°)
- Sine waves with ±1-50% DC offset
- ±DC with 3% and 10% ripple
- Fourier square waves with harmonics
- Taylor series waves
- Sine wave with noise at zero crossing

third, fifth and seventh harmonics

SmartWave Control Suite (SWCS)
SWCS is a Windows based software package for computer control of the
SmartWave Series and SWAE AC power sources. With the SWCS you have complete control of
the instrument including programming, waveform selection, creation and sequencing.
SWCS enhances the standard SmartWave features with an additional harmonic waveform
analysis capability with data logging features for all measurements.
