NOTES:
(1) See functional schematics.
(2) Load current at +24 VDC.
(3) Recommended per channel output level based on 150x 6 MHz QAMs with up to four analog channels at 6 dB above these levels. Maximum output levels in graph are stated as the point at which 40 dB MER is approached yet pre-FEC BER of 256 QAM <1E-9. ATX recommends operating 2 dB below these levels to
account for even doubling of amplifiers in cascade and another 3 dB for margin for a total of 5 dB de-rating from maximum. If 43 dB headend MER is the target instead of 40 dB, derate amplifier output by a further 2 dB. Note that under same test conditions of all digital loading, the legacy QMP1000-34GPF series
amplifier performs same as new QMP1000-35GPF.
(4) See chart for other maximum output ratings for the number of QAM channels.
(5) Linear or cable tilt values 2-20 dB (can be ordered separately), see page 4.
(6) Output TP is relative to RF Out. Input TP is relative to true input to first stage of amplifier, not to RF Input of module. There will be a negative slope if measured
relative to RF Input because the input circuitry before amplifier stage (see schematic) has this slope.
OTHER NOTES:
IS = Interstage; IP = Input; OP = Output Operating temperature: 0°C to +50°C (+32°F to +122°F)
All testing specified with 0 dB attenuators & EQ unless otherwise noted. Humidity: 5-95% (without condensation)

NOTE:
* Values based on 48 MHz of total loading (add 69 dB for 8 MHz QAM, or 67.8 dB
for 6 MHz QAM, or 66 dB for 4 MHz QAM). Target BER <1E-8 for 16 QAM modulation.
Minimum/maximum composite RF detection level in software is 20.5/80 dBmV.
