Three displays are provided for indication of the nominal and actual values. A separate display is provided for status information and menu-guided operation. For module testing, NGPT35 provides the possibility of varying the output voltage of all three channels simultaneously in percent. After selection of the channels to be included in this operating mode, the desired variation can either be set via the numeric keypad or in steps of 0.1, 1 or 10% using the increment/decrement keys. Features Insensitive to RF voltages radiated by device under test or nearby antenna Very low PARD (periodic and random deviation) due to linear regulation 14 bit resolution Precise and stable over wide temperature range Simultaneous readout of nominal and actual values of all channels Output voltage of all channels simultaneously variable by a percentage value Nonvolatile storage of up to six complete setups Software calibration via IEC/IEEE bus without potentiometer adjustment Coupled protection mode for DUTs which should not be supplied from an asymmetrical voltage source Floating outputs, max. 120 V DC Remote sensing (0.5 V per lead) Soft limits for defined voltage and current limiting Hardware overvoltage protection Quiet, temperature-controlled fan 19" system unit, full system capability via IEC/IEEE bus interface (IEC625-1/IEEE488-2)
