Schaffner NSG 500C/506C EMC Test System for Automotive Electronics
The
NSG500C unit contains two generators in a compact form; one for the microsecond pulse
range (pulses 1 and 2) and the other for the fast pulse bursts in the nanosecond range
(pulses 3a and 3b), together with a common control section.
The rise time, pulse width and amplitude of the pulses 1 and 2 can be varied
within wide limits. Facilities are provided to connect external impedances to match
the generator to the conditions such as are to be found in a vehicle's supply system.
The pulse bursts, 3a and 3b, can be set in amplitude and polarity to suit the
test specification.
The front panel is equipped with a presettable counter which enables automatic
tests to be carried out for a predetermined time or number of cycles. Triggering can
be set for manual or external operation and a trigger output is provided to drive an
oscilloscope.
Dampening of the interference pulses by the supply source is prevented by a
built-in network.
