, Charter passing modem receive levels (Rx) - ANS between -10dBmv and +12dBmv
Charter passing modem transmit levels (Tx) - ANS between 35dBmv and 50dBmv
Charter passing MER - ANS 35dBmv
HD channels - ANS around 10Mbps each
standard definition channels - ANS around 3-4Mbps each
QAM (qaudarature apmlitude modulation) - ANS two amplitude modulated waveforms at
the same frequency that are phase shifted by 90 degrees
QPSK (qaudrature phase shift keying) - ANS 16 QAM, 64 QAM, and 256 QAM are all
exapmples of QAM modulation.
RF loss or gain - ANS is a relative measurement and is measured in dB (decibels)
RF measurements that are read from a meter are - ANS absolute measurements and are
measured in dBmV (decibels per millivolts)
Analog signal loss - ANS is often gradual and reduces signal slowly
Digital signal loss - ANS sudden where very small margin exists for difference between a
good picture and no picture (called the cliff effect)
FM radio stations - ANS found between frequencies 88 MHz and 108 MHz
frequency - ANS number of fully completed cycles per second
