NSG 3040 EMC test system
12.3 Function check
The safety measures described previously must be
strictly observed while carrying out a function check.
As soon as the test system is switched on the Power-LED should light up. If
this is not the case then please check the mains power connection to the test
system as well as the fuses, voltage selector and any other cabling.
The instrument automatically carries out a diagnostic routine once it has been
successfully switched on.
The generator cannot perform any test while the interlock circuit is open.
Pulse generation can be observed at the output connectors by means of an
oscilloscope. This is a practical way to check that the system is functioning
correctly but should never be used for reference or calibration purposes.
Do not connect the oscilloscope directly in order not to
exceed its max. input voltage.
Teseq recommends the use of a HV differential probe
type MD 200 or MD 200A along with the INA 6560 safety
banana adapter as well as CAS 3025 and MD 300 or
MD 310. (See paragraph: accessories).
12.4 Calibration
The combination of high voltages and high frequencies in a single pulse makes
the calibration of EMC pulse generators particularly demanding and difficult.
Teseq has one of the few accredited test laboratories in Europe that is in the
position to undertake calibrations in this specialized field.
