Rohde & Schwarz NGPT7
Programmable Triple Power Supply
Description
Key Points
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)
