Connections of external shunt resistors
An external shunt resistor of R = 2.5
Ω
/ 400W (at U = 30VDC) may be connected to the related safety
banana sockets. Together with the existing incorporated resistors it results a total resistor value of 2
Ω
. The
2
Ω
value is required when measuring transient emissions as per ISO/DIN 7637 standard.
10 Selection of the shunt resistor
With this knob the shunt resistor can be switched to 40
Ω
, 10
Ω
or to an external resistor (see point 9.)
11 CRO Trigger
During the
switching-off ramp a trigger signal (+ 15V) is generated and is available at the
CRO Tigger
output.
12 CRO measuring output
The measured transient emission signal is available at the
Monitor
output. The AN 200 includes a resistive
divider with a divider ratio of 1:100 and an accuracy of
±
2% .
13 LED display indication of Switch-On status
The
LED indicates the On-status of the electronic battery supply switch. In this case the DUT is connected to
battery supply.
14 Connection for device under test (DUT)
The DUT is connected at the safety banana output sockets.
