Notes:
1 Downstream Power has 18 dB internal padding.
2 The transponder output is limited to a maximum of 40 dBmV at the transponder
1 Downstream Power has 18 dB internal padding.
2 The transponder output is limited to a maximum of 40 dBmV at the transponder
RF connector so as to not exceed manufacturer specifications. This is
accomplished through a 15 dB pad in the upstream RF path within the
transponder.
It is possible for the transmit power reading on the web page to exceed 40 dBmV
by a significant margin if the transponder cannot reach the CMTS requested
transmit level. This high reading on the web page has no adverse impact on
operation of either the transponder or the node.
As the CMTS requests the transponder to transmit at a level beyond its capacity,
the web page display can show a slowly increasing power level up to the
maximum DOCSIS level for that particular transmit mode and modulation type.
Even though the level reading on the web page is high, the transponder output is
still limited to 40 dBmV. This condition can occur where the upstream
attenuation between the node and CMTS is significant. Under normal conditions,
the web page display and actual RF output level are the same.
