  • Programming the HVA Series Precision High Voltage Amplifier
    to observe the polarity of the applied signal. The voltage is always positive because the current limiting circuitry seeks the absolute value of the current and limits the value -- without regard to polarity. The input characteristic is high impedance with a 10M O pulldown to ground. Enable/Disable
