
Setting value and actual output
Since the output of the BP4620 is influenced by the frequency characteristics of the amplification
block, a difference occurs between the amplitude setting value and the actual output amplitude in the
case of a high frequency.
Figure 4-9 shows the relationship (representative example) between the setting values on the
operation panel and the actual output values.
The frequency characteristics vary according to the load condition, response characteristics, output
waveform, load cable length, etc.
