Operation Overview
Dynamic Load Frequency Sweep Mode
Figure 3-12 CC dynamic Frequency Sweep Current Waveform
The Load offers a unique CC dynamic frequency sweep with variable frequency to find the
worst case UUT voltage.
Frequency Sweep Function operation enables you to program two load levels (Load1 and
Load2), Start frequency, End frequency, Step frequency, Dwell time, duty, slew rate (Rise
and Fall). During operation, the loading value is switched between those two load levels
according to such user specified parameters.
Frequencies (Start frequency, End frequency, Step frequency Hz)
The setting range of the Frequencies is from 0.01Hz to 50kHz.
Dwell time (s)
Dwell time is the elapse time of each setting step frequencies from start frequency to End
frequency. The setting range of the Dwell time is from 1ms to 100s.
Duty (%)
The duty in percentage of Load1 is in one dynamic loading cycle, and it is expressed by %.
The duty can be set from 1%-99%. The Duty setting will be limited within the transition time
of the two load levels.
