I have a large (2KW) Bird 30db attenuator. I believe 30db is a factor of 1,000, so 2KW in gives me 2 watts out.........Now, if I run the output of the attenuator into a 50 watt (LOTS of head room) dummy load, I can use this setup as a 2KW dummy load ?? Almost sounds too good to be true!
I will be using this with an Alpha 86 and a Ten Tec Titan 425. I would like to be sure this setup will work the way I think it will......... I don't want smoke a pair of 3CX800A7's.
Thank you for your input.
73 de bob,
My standard bench loads are a 2kW Bird 30 dB attenuator (no termination is required) and when I need high power a water cooled 50 kW 30 dB attenuator with a 3" flange.
Neither requires any pad, because a 30 dB attenuator has 60 dB return loss. Any load you add is meaningless.
