 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. \\  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.

 +This voltage limit circuit in the DHV hardware limits the voltage (including the modulation input) to the user defined limit when using the G=20 V/V mode.  However, this hardware limit will not cap the modulation input in the G=1 V/V.  Therefore, the output with a +10 V modulation input can exceed the user defined limit by 10 V when operating in the G=1 V/V mode.
 ==== Setting the Bias Voltage ==== ==== Setting the Bias Voltage ====
 To set the bias voltage about which the SLICE-DHV will operate on a given channel, touch the DC Bias [V] field on the Home screen.  Depending on the length of the touch, either a view similar to <imgref Vset_knob> allowing rotary knob input or a keypad similar to <imgref keypad> will be displayed.  Set the nominal bias voltage. \\  To set the bias voltage about which the SLICE-DHV will operate on a given channel, touch the DC Bias [V] field on the Home screen.  Depending on the length of the touch, either a view similar to <imgref Vset_knob> allowing rotary knob input or a keypad similar to <imgref keypad> will be displayed.  Set the nominal bias voltage. \\

-The user can input an analog voltage signal to control the output of the SLICE-DHV. Before introducing a control signal, make sure you have selected the [[slice:dhv#Setting_the_Operation_Mode|desired Gain/operation mode]] (HBLG or LBHG).  \\ +The user can input an analog voltage signal to control the output of the SLICE-DHV. Before introducing a modulation signal, make sure you have selected the [[slice:dhv#Setting_the_Modulation_Mode|desired modulation mode]] (Unity Gain or Full Range).  \\ 
  
-The default modulation input is the SMA connector on the rear panel (bubble 3, <imgref back>).  The user can also program the SLICE-DHV to accept the modulation/control signal from the front-panel INPUT A for Channel 1 and INPUT B for Channel 2.  Only one modulation input for a given channel can be active at any given time.  To toggle between modulation input locations touch the I/O icon on the control bar and then the relevant INPUT field (A for CH1 or B for CH 2; <imgref input_a>). Select OFF for rear-panel input or Modulation Input for front-panel input.+The default modulation input port is the SMA connector on the rear panel (bubble 3, <imgref back>).  The user can also program the SLICE-DHV to accept the modulation signal from the front-panel INPUT A for Channel 1 and INPUT B for Channel 2.  Only one modulation input for a given channel can be active at any given time.  To toggle between modulation input locations touch the I/O icon on the control bar and then the relevant INPUT field (A for CH1 or B for CH 2; <imgref input_a>).
