1 DUT test supply input
The power supply for the EUT is connected to the safety laboratory conn and -. The front panel output is
decoupled by the internal coupling/ decoupling network.
2 Reference ground connection
The generator has to be connected to the reference ground plane of the test set up. Very important is the
connection at the front panel of the simulator.
3 External trigger
One single burst event can be released. Trigger level 5-15V positive going.
4 Mains selector
Selection of 115V / 230V
5 Power on switch
The switch is part of the mains filter. Mains fuses are part of the filter. (230V / 1A and 115V / 2A )
6 Safety circuit
To connect an external security circuit.
7 Serial interface
RS 232 interface with a 9-pole connector.
8 Remote control connector CN
To connect to the external coupling matrix CNE 503. All functions are controlled by the EFT 500. It is
recommended to connect and power the CNE 503 before turning the power mains ON at the EFT 500.
9 Parallel interface GPIB / IEEE 488
IEEE 488 interface with IEEE connector.
10 Fail detection FAIL 1 (TEST STOP)
The BNC input FAIL 1 can be used for DUT monitoring. In case of a low going signal (to chassis ground) the
EFT 500 will stop pulse generation and the actual running test routine is paused. The test routine than can be
stopped completely or can be continued from break point.
A message of FAIL 1 is indicated in the LCD display as well as in the ISM ISO software.
10 Fail detection FAIL 2 (TEST PAUSE)
The BNC input FAIL 2 can be used for DUT monitoring In case of a low going signal (to chassis ground) the
EFT 500 will stop pulse generation and the actual running test routine is paused as long as the low level signal
is available at the FAIL 2 input.
The test routine continues automatically as soon as the low level signal goes to high level.
A message of FAIL 2 is indicated in the LCD display as well as in the ISM ISO software.
