7.1.3 Lx/Ls Series –ABD Option Limitations
The extent of coverage of the –ABD option as implemented on the Lx/Ls Series platform is shown in
the table below. Tests marked with an „x‟ generally require additional hardware to be used. Tests
marked with a „P‟ require arbitrary waveform capability, which is available on Lx models or Ls models
with the –ADV option only.
Note that the Lx/Ls Series only provides AC output so none of the DC tests (Table D and E) are
supported on the Lx/Ls Series.
Harmonic Measurement Restrictions
The maximum bandwidth for current harmonic measurements of the Lx/Ls Series is limited to 48KHz
in single-phase mode and 16 KHz in three-phase range. Harmonic components that fall outside this
bandwidth are not reported (value of 0.00 is returned). The same applies to voltage harmonics.
The requirement for ABD is 150 KHz so for EUT‟s with high harmonic order currents, a higher
bandwidth external power analyzer should be used in addition to the AC source.
