AMPLIFIER RANGES – FRONT PANEL MENUS AND OPTIONS
The LVA 4-Quadrant Amplifier offers four standard voltage ranges: 20VDC 36VDC 54VDC
70VDC With the built in oscillator unit the amplifier’s input signal can be: DC signal Sine wave Rectangular wave Triangular wave Ramp (amplitude sweep) User defined Alternatively an external signal generator can be used. For each voltage range the operating mode options can be selected. With the option “OPD” (over-voltage protection device) the EUT’s supply voltage is monitored and the EUT is protected against very fast rising high voltage. The LVA allows optionally specifying the amplifier’s internal resistance from 0 to 200mΩ in each mode of operation. Optionally the sink mode capability can be disabled.
