NSG 5500 Automotive transient immunity generator

2.7.1 Test set-up

The following set-up can be used to check the integrity of the output pulses. The scope probe should be in 
conformance with the specifications outlined in ISO 7637-2.

2.7 Installation / set-up LD 5505 and LD 5550

Check the instrument for any mechanical damage. Report any damage found to the carrier immediately.

Both LD 5550 and LD 5505 modules are in usage. The term “LD Module” is used to refer to either of these 
modules. All of this information applies to both modules unless specifically refenced by module name.

Ensure that the power is turned off on the NSG 5500 mainframe and that the battery input is disconnected. 
Insert the cassette in the right most slot and push in fully. Screw in the four retaining screws fully.

If using the battery switch, ensure this module is present and inserted fully in the rear of the NSG 5500 
mainframe.

It is vitally important that the unit is connected to a good, protective earth.

Turn on the mains input power on the NSG 5500 mainframe. After approximately a two second delay the 
power LED (red) on the LD module should light. After a further two seconds of initialisation, the unit is ready 
for operation. The software communications will not start correctly until this initialization time is complete.

Now the scope test setup shown in picture 2-9 below 26 should be connected and the output pulses should 
be quickly checked to ensure that they are of the correct form and shape. When pulses are being generated 
the relevant green LED (5 or 7, whichever is selected) should flash as pulses are output.

When correct operation has been verified, the DUT can be connected to the “OUTPUT” terminals at the front 
of the unit, and the required tests can be carried out.
