- | The SLICE-DHV features two modulation modes: a unity-gain mode and a full-range mode. The unity gain mode has a 1x voltage gain with a limited operating range of ±10V (-10 V to +10 V input) that is centered around a user-settable DC bias voltage. The full range mode has a 20x voltage gain that operates over the entire 200 V range (0 V to 10 V input). The unity gain mode has better noise performance than the full range mode. | + | |
+ | The SLICE-DHV features two Gain values: G=1 and G=20 for the input modulation signal. When G is set to 1, the output range is limited to ±10V from the user-settable DC bias voltage. When the Gain is set to 20, the modulation input signal allows access to the full range of the SLICE-DHV (0-200 V). When the Gain is set to 1, the SLICE-DHV has better noise performance than when the Gain is set to 20.\\ | ||

- | The SLICE-DHV has two modulation modes: a Unity Gain mode and a Full Range mode. In Unity Gain mode the input modulation signal is directly summed with the DC Bias to produce the high voltage output. This mode is useful for limiting the voltage range of the high voltage output to ±10 V around the DC Bias operating voltage. The Unity Gain mode will also exhibit less noise than the Full Range mode, dependent on the noise level of the modulation input signal. \\ | + | The Gain on the input control signal can be set to either 1 or 20. When the gain is 1, the input modulation signal is directly summed with the DC Bias to produce the high voltage output. |
