I'm testing a pair of your 2005 Multi-mode modems and I would like to know
what the power output of the units ( in dB ). I have power metered them and they are both outputting at -28.0 dB. The data sheets only talk about the
power budget as being 15 dB. If the LED's output at -20.0 when new, then they are still outputting within the power budget which should be -35.0 dB?
The transmitter output you measured is correct at -28 dBm. The receiver
sensitivity is -43 dBm for the 2005 Bit-Driver. This is how you get the 15 dB budget.
