  • 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.

  • AMPLIFIER CHARACTERISTIC – 4-QUADRANT OPERATION

    The LVA amplifier is a real 4-Quadrant Amplifier. Due to this advanced technology four different application scenarios are possible:

    -U/+I

    +U/+I

    II. Quadrant negative voltage, positive current LVA 2500 example values: Utest Isink cont Isink short -12V 33ADC 66ADC

    Typical application: The LVA simulates a voltage drop of the negative testing voltage and the EUT’s input has a capacitive stage feeding energy back into the LVA

    III. Quadrant negative voltage, negative current LVA 2500 example values: Utest Icont Ishort -12V -33ADC -66ADC

    Typical application: The LVA supplies negative testing voltage to the EUT

    IV. Quadrant positive voltage, negative current LVA 2500 example values: Utest Isink cont Isink short 12V -57ADC -114ADC 24V -43ADC -86ADC 48V -30ADC -60ADC
