presets are the out put voltag es
(0.5kV, 1.0kV, 2.0kV and 4.0kV) and
the burst frequency (5kHz / 100kHz)
A test mode to preset the output
voltage and variation of the burst

the test. The voltage variation is set
from 500V to 2500V per 250V step.
This is efficient function to judge
malfunction point of EUT and can
also set variation of conditions for
the output voltage, burst frequency,
polarity, injection phase.

Accurate waveform realized by high voltage high frequency technology
High accurate and stable output is realized by reviewing the circuit and element in the past entirely, and gathering the analog technology of
the high voltage / high frequency. Consequently, it can be responded to diversified EMC environment with the improvement and upgrade
of the output voltage to 4.8kV from 4.5kV and the burst pulse frequency to 2MHz form 1MHz as well as realization of the high accurate
output waveforms from the CDN.
