 ====== SLICE-DHV Dual-Channel High-Voltage Amplifier ======
-<WRAP center round box>The SLICE-DHV is a low-noise, high-bandwidth, high-voltage source with DC bias control and sweep capabilities.  It is designed for controlling piezoelectric transducers used for precision positioning, with particular application to laser frequency stabilization.  The high-voltage output can range from 0 to 200 V, has a voltage noise < 500 µV rms, can drive ±200 mA, and has an unloaded small-signal (±10V) bandwidth > 1 MHz. The SLICE-DHV also has a user-settable voltage limit for safe operation at voltages less than 200 V.

The SLICE-DHV also has a user-settable voltage limit for safe operation at voltages less than 200 V.
-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 is not recommended for applications that require a large-signal bandwidth greater than 20 Hz, defined for modulation amplitudes more than 10 V.
