NSG 5500 Automotive transient immunity generator
3.2.3 NSG 5500 System overview
The NSG 5500 mainframe is designed to take the pulse plug in units from the front. The system support
electronics are plugged in from the rear.
Picture 3-3: NSG 5500 Rear view.
These rear plug in units are not generally removed by the user. These units have a modular construction to
facilitate easy maintenance and to allow for future upgrades to the NSG 5500 system. The plug-in units in
question are,
HV-PSU 5500:
this is a solid state high voltage programmable power supply that provides the required
charging voltage to the pulse generators.
CDN 5500 or CDN 5501:
this unit contains a solid state switch and timing electronics which are used for precise
timing control of the “ON“ and “OFF“ periods of the battery power supplied to the device under test (DUT).
This is required to meet some of the timing requirements specified in the standards, particularly for negative
pulses.
CTR 5501 or CTR 5502:
this unit contains the processor board that controls the complete system.
The remote control interfaces USB and IEEE 488 are also available via this unit.
NOTE!
The difference between the CTR 5501 and CTR 5502 is that the CTR 5502 can be
upgraded with up to eight ARB 5500 arbitrary waveform generators.
