Hey folks,
I´d like to swap the original L-pads in the 4355 to some fixed resistors.
Which values would I need to reach the +4db setting of the L-pad for the HF and UHF section
Thanks a lot,
Olaf

Thanks for your help
Actually I haven`t got the oppertunity to measure the values, sorry. But you think I could simply bypass the L-Pads!?
3155 has two L-pads. One 16 ohm and one 8 ohm.
Remove L-pad will affect the crossover frequency.
Set L-pad to +4, disconnect cables and measure the value between the legs.

This is what I found for the 8ohm L-Pad. But I´m not shure how to read this....
The "series resistor" (3 to 2) varies from 7.2ohms to 0 ohms, so I guess I could simply cancel this resistor!?
But which value does the remaining "parallel resistor" has to be ?
If you can find my 3155 charge coupled schematic it should have the fixed resistor values in it.
Thanks for the hint
So it would be none series-resistor and a 100giga-ohm in parallel ?
No, the 16 ohm L-Pad measured 8 ohms in series and 22 ohms in parallel at the 0 position and the 8 ohm L-Pad measured 4 ohms in series and 22 ohms in parallel at the 0 position.
I'd say to make sure the 100Gig ohm resistor is non-inductive
and that 1% might sound better, but someone might take me seriously.
(a -really- poor idea)
Sometimes including non-physical parts (particularly DC resistive paths to ground)
help electrical simulations run properly.
