However, if switching between two channels is desired, two ceramic filters are required. The minimum allowable bandwidth of the ceramic filters is +/-70 kHz @ 3dB. Narrower bandwidth limits the maximal bit rate. The SIG40 selectable frequencies are designed according to the market available ceramic filters.

The DC cable length has less effect on communication. The SIG40 needs at least 20mVpp for proper reception. Good communication should be achieved if the transmitted signal can be seen on an oscilloscope at the receiving side within the line noise. |
