HV-Amplifier (SP 908)

If the standard ±10 V voltages, generated from the LNHR DAC (SP 927), are too low the HV-Amplifier with a voltage gain of ten can be used. It has an output voltage of up to ±100 V with a maximum output current of ±70 mA. To prevent from ground loops, the analog in/out are floating and not referenced to the ground/earth carried by the 230 V mains. An analog voltage-indicator on the front-panel shows the actual output voltage. The device can be used to drive capacitive-loads such as piezo-electrical crystals. The bandwidth can be switched between 10 kHz and 100 kHz; this makes it compatible with the Analog Selector Switch (SP 944).
