Schaffner NSG2025 Fast Transient / Burst Generator
The Schaffner NSG 2025 EFT Burst Simulator is a high end
burst generator and the choice for users who need the maximum in pulse
amplitude/frequency capabilities, flexibility, coupling network features
and EUT connectivity. Based on a "building block" concept, the Schaffner
NSG 2025 lets you select and combine pulse generator, coupling and EUT
adapters to create a flexible, upgradeable EMC test work station to match
your needs today and into the future. It covers all the widely used burst
test specifications of IEC, EN, ANSI-IEEE as well as the known extended
manufacturer's requirements.
The Teseq / Schaffner NSG 2025 Fast Transient / Burst Generator offers the most
extensive range of pulse voltages and burst frequencies available in a
single instrument. Pulses can be coupled into the mains supply voltage or
applied as a pure high voltage for data and signal line testing.
Pre-programmed IEC standard tests are
available at the touch of a button and pulse parameters are user
configurable - manually via front panel control or via PCWindows software
control. Not only does the Teseq / Schaffner NSG 2025 meet all the requirements of
current world test standards with comfortable margins, it also anticipates
likely future modifications with functions including a user-configurable
burst frequency to 1MHz and extended selectable coupling modes.
