 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), and to switch the SLICE-DHV into its Current Limited modulation mode if larger modulations (G=20 output mode, > 20 Vpp modulation) are required. This will help to prevent thermal shutdown. Certain systems may require different settings than these, though, depending on their specifics. For a more in depth discussion of choosing between Full Bandwidth and Current Limited, see our application note "Load Size Selection and Limiting Factors of the SLICE-DHV’s Modulation Output", which can be found on our website under "Application Notes".

 ==== Setting the Voltage Limit ====
 The user can set the maximum voltage output on a given channel so as not to exceed the rated maximum for their device.  From the Home screen, touch the CH 1 (or CH 2) field to see <imgref CH_settings>.  Touch the Voltage Limit [V] field to set the maximum voltage output. The bar graph output indicator on the Home screen will scale automatically with the maximum voltage set point. \\
