The LD 5550 (LD = Load Dump Generator) is a plug-in high energy generator module designed for use with the NSG 5500
mainframe system. It is designed primarily to meet the specification requirements for the ISO 7637 standard for pulses 5 and 7. In many cases the specification of this generator exceeds those specified in the ISO 7637 standard.
When slotted into an NSG 5500 mainframe the LD module is fully programmable via USB or RS 232 and IEEE 488 interface. Parameters such as amplitude, pulse frequency, pulse width, are all under program control.
