+ | ====Choosing Current Limited or Full Bandwidth==== | ||
+ | On newer models of the SLICE-DHV, a feature was added which allows the user to switch the Modulation Mode of their unit between Current Limited, and Full Bandwidth. These two modes control the amount of drive current which can be sent through the output op-amp to modulate the load attached to HV out. In Full Bandwidth mode, the current through the op-amp is not limited, giving the SLICE-DHV a larger modulation bandwidth. The drawback, however, is that the output op-amp will occasionally go into thermal shutdown, or show distortions when driven especially hard, or with larger loads. In Current Limited mode, the output op-amp is throttled slightly to prevent the thermal shutdown and distortions seen in Full Bandwidth mode. However, using Current Limited mode slightly reduces the overall bandwidth of the system. | ||

+ | It is recommended to use the Full Bandwidth modulation mode if in the small signal regime (G=1 output mode, < 20 Vpp modulation), | ||
