BOP 36-6ML/031512
If the load impedance at the working frequency multiplied by the peak value of current
equals the voltage limit setting, it is recommended that the output voltage be kept below the
voltage limit setting to avoid inducing a large distortion of output current. If the voltage limit is
reached, the unit’s bandwidth can be reduced by connecting an external film capacitor between
pins 16 and 18 of the unit's programming connector (PC 12). Table 2 below shows the effect
that adding the external capacitor has on the 3dB bandwidth for resistive, resistive-inductive or
inductive loads, with less than 10% tolerance (excluding the capacitor tolerance)
