SPECIAL AMX SERIES OPERATING FEATURES
CONTINUOUS SELF CALIBRATION
Provides for exceptional accuracy of the AC output Voltage. When enabled, accuracy improves to
±
0.03% referenced to the power
source internal voltmeter.
PROGRAMMABLE DYNAMIC OUTPUT
IMPEDANCE (OPTIONAL)
Provides positive or negative output impedance. The output voltage waveform at
the right is flattened as a result of a high peak load current drawn by an electronic
load at the peak of the sinewave.
Engaging the dynamic output impedance (Zº) feature dynamically compensates,
as shown at the right, for the distribution or transformer losses up to
±
10% of the
output voltage.
WAVEFORM LIBRARY
Up to 99 different waveforms may be stored in the waveform library for execution
as part of a steady state test program or for substitution in any output phase as part
of a transient test program. Memory location #1 is a non-editable high resolution
sine wave. Locations 2-16 are editable and may be substituted in any output
phase. Locations 19-99 are factory stored, non editable waveforms that may be
copied to 2-16 for edit and execute.
WAVEFORM LIBRARY
Up to 99 different waveforms may be stored in the waveform library for execution
as part of a steady state test program or for substitution in any output phase as part
of a transient test program. Memory location #1 is a non-editable high resolution
sine wave. Locations 2-16 are editable and may be substituted in any output
phase. Locations 19-99 are factory stored, non editable waveforms that may be
copied to 2-16 for edit and execute.
WAVEFORM EDIT
Provides the ability to modify a stored waveform by specifying the waveform
amplitude desired at each specific phase angle. This method can be used to
quickly create spikes, dropouts, notches and other sub-cycle wave conditions. The
resulting modified waveform can be stored for execution.
WAVEFORM ANALYSIS (OPTIONAL)
Provides both a graphic and numeric display of the harmonic structure of a
voltage or current waveform. The waveform is sampled at 512 samples per cycle
using a 12 bit A/D converter. The resulting high fidelity waveform is analyzed for
its harmonic structure up through the 51st harmonic. Data presented includes
the magnitude of each harmonic in %, the total harmonic distortion, and the odd
and even harmonic distortion in %.
WAVEFORM SYNTHESIS (OPTIONAL)
Provides the ability to quickly create virtually any AC Test Waveform that may be
required by building it out of harmonics. The process is as simple as keying in the
harmonic multiple, the amplitude, and the phase angle for each desired harmonic
up through the 51st. If desired, waveforms may also be created in the time domain
by making entries from the front panel or by downloading from a host PC.
TIME BASED TRANSIENTS
Provide the ability to create and execute on command, transients that
occur linearly over a specified time segment to modify output voltage or
frequency.
CYCLE BASED TRANSIENTS
Provide the ability to create and execute, on command, transients that
substitute a selected waveform in the output for 1 to 100 cycles. The
waveform being substituted can be selected and/or modified from the
waveform library. Substitution is for an integer number of cycles,
regardless of frequency.
