Non-Invasive Stability Measurement (‘NISM') software for VNA

 


Picotest has released Non-Invasive Stability Measurement (‘NISM') software for the popular Rohde & Schwarz ZNL Vector Network Analyzer test instrument series. The software allows VNA users to physically test the stability of a power supply via output impedance, including phase margin, even when a Bode plot cannot be measured. This is the third major VNA test instrument company to support the Picotest's NISM software tools.The software add-on, available now for new or existing customers, allows the instrument to perform non-invasive stability margin ("NISM") measurement. NISM is an alternative to a Bode plot measurement that allows the user to test circuit or filter stability even when the control loop is not accessible. It determines phase margin from an output impedance measurement via group delay. This capability, available for several other VNA instruments (including OMICRON Lab's Bode 100 and Keysight's E5061B and E5071C), allows the user to measure the stability of op amps, voltage references, voltage regulators, LDOs, switching amplifiers, POLs, input filters and all types of power converters through their output impedance.
