All testpoints are directional and referenced to their associated RF port. For “H” output option, all forward and
return testpoints are internal and only accessible with the housing lid open. For “P” output option, all forward
testpoints are external and all return testpoints are internal.

Power requirements indicated are with the HEPS790–2.3 power supply 122027–05. See 333995–17 for additional
information. For 60VAC Powering: AC Power consumption in Watts divided by a factor of
43 = Amps required. For 90VAC Powering: For
≤
67VAC, 1.03 x (AC Power consumption in watts divided by voltage)
= Amps required. For 67 - 90VAC, AC Power consumption in watts divided by 65 = Amps required.
16.
ALC pilot level range is based on a nominal pilot level of 43 dBmV for pilot frequencies
≤
499.25 MHz or 39 dBmV
for pilot frequencies > 499.25 MHz. C-COR recommends that if the pilot level, from a design standpoint, is more
than +2/-1 dBmV from nominal, the ALC PAD should be changed to optimize the ALC pilot level range. This should
alleviate any possible ALC setup and/or operation issues due to typical system level variations caused by system
components flatness characteristics. See the FM901e equipment manual for correct selection of ALC PAD value to
insure proper ALC setup and operation.
17.
For ALC pilot frequencies of
≤
499.25 MHz and below, the ALC pilot filter is a single channel device. This means that
the adjacent channels will have no affect on the RF power level that the RF detector is measuring. For ALC pilot
frequencies > 499.25 MHz, the ALC pilot filter is not a single channel device. This means that the adjacent QAM
channels will have an affect on the RF power level that the RF detector is measuring. C-COR recommends that the
adjacent QAM channels be present on the system before the ALC system of the amplifier station is balanced. This
will avoid station re-balance in the future when those QAM channels would be added to the system.
