SVF 106 Tests
Voltage distortion spectrum test require the use of additional external equipment. In particular, a
high bandwidth (100Khz) AC source, a high frequency coupling transformer and coupling
network as shown in figure SVF106-1 of the Mil-Std 704 standard. For this test, the Lx/Ls Series
AC source can be programmed to a steady state condition of 360, 400, 600 and 800 Hz and
Vnominal of 115 Vrms or 230 Vrms.
