1
Ventilation
This guarantees cooling of the battery supply switch. Ventilation grid and ventilator (blower) must be kept
away from other devices in order to allow sufficient air flow through the battery supply switch.
2
Reference earth connection
This plug is for connecting the AN 200 to the ground reference plane.
3
DUT supply
The battery supply (+) & (-) for the DUT is connected to this input. The nominal dc supply parameters
allowed are 30V / 25A .
4
Measuring output with 50
Ω
coaxial resistor
For measuring conducted emission spectrum on battery supply lines as per ISO/DIN 7637 and
DIN/VDE 0879 an artificial network, as illustrated in chapter 3.3, is compulsory. For this the required the 50
Ω
resistor Rz is coaxial and located on the BNC plug.
For measuring the interference spectrum a test receiver or spectrum analyzer with 50
Ω
input impedance is
used. The instrument is connected to this BNC socket and the 50
Ω
coaxial resistor is replaced by the 50
Ω
input impedance of the measuring device.
5
Power on switch
The switch is part of the mains filter. Mains fuses are part of the filter.
