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.

| | <WRAP important></WRAP> |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 does not cap the modulation input in the G=1 V/V. Therefore, when operating in the G=1 V/V mode, if the user were to set the nominal voltage set point to the user-defined maximum voltage output point, the output with a +10 V modulation input would exceed the user-defined limit by 10 V | |
==== 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.

==== Modulation/Control of the SLICE-DHV Output ==== | ==== Modulating the SLICE-DHV Output ==== |
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.

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>).
