EMSET Variable Affinity Control Equivalent & Access
ALC_MODE_SELECT This parameter places the upconverter either in
ALC Auto or ALC Manual mode. The output power
level is only controlled automatically in ALC Auto
mode, which is the normal operating mode.
ALC_AUTO_REF_MIN This parameter sets the minimum ALC level and is
normally set to zero.
ALC_AUTO_REF This parameter sets the ALC Auto full power level.
ALC_MANUAL_REF This parameter sets the ALC Manual power output
level.
FAST REFLECTED SHUTDOWN THRESHOLD This parameter sets the trip point for the -6dB
power reduction at 15% reflected power.
POWER LIMITER This parameter sets the maximum overpower
output limit.
FILTER_COEFF_1 This parameter sets the number of averages used
for the "Fwd" and "Refl" power readings in the
upconverter LCD display and is normally set to 7.
FILTER_COEFF_2 This parameter sets the number of averages used
for the "Upconverter Internal Fwd" power reading in
the upconverter LCD display and is normally set to
7.
SYSTEM FWD PWR REFERENCE This parameter is the calibration value for the
upconverter LCD "System Forward Pwr" reading.
SYSTEM REFLECTED PWR REF This parameter is the calibration value for the
upconverter LCD "System Reflected Pwr" reading.
UPCONVERTER INTERNAL FRD PWR REF This parameter is the calibration value for the
upconverter LCD "Upconv Forward Pwr" reading.
SYSTEM REFLECTED POWER PERCENT LIMIT This parameter sets the trip point for 25% reflected
power at the (already) –6dB reduced output level.
UPCONV HEALTH PLAN MASK This parameter selects the features and
capabilities of the upconverter. It is typically set to
65403 or 65407 (Rev B Upconverter).
UNUSED WORD 1 This parameter is normally set to 21. It is normally
used only in multi-channel frequency-agile Affinity
systems.
