Stefan,
if I understood correctly, the datasheet says that the impedance is 18
kohm if you use the red and green wires and 500 ohm if you use the
yellow and green ones; so you should load both sides with 18 kohm in
your case, or change taps.
Then you should also load the filter with the exact capacitance values
printed on its ends, connected between the red and green wires.
Regards,
Claudio

The input signal is connected on the left side between the red and green
wire. The output signal is taken from the right side on the red and
green wire too. It looks as if each side has a coil on the green and red
wire, with a tap at the yellow wire.
Helpful was this image from the web
http://www.amateurfunkmuseum.de/AFM_321b-Dateien/image006.jpg which
shows a similar filter. I have connected a resistor of 18 kOhm to the
output and a 500 Ohm resistor in series to the signal generator, as
stated in the datasheet. But the ripple does not change.
Any ideas or suggestions?
Guess for what i will need the filter! :-)
