Notes
1. Total integrated power, detectable range.
2. MER Typical defined as identical QAM carriers at +5 dBmV
with no adjacent analog carrier.
3. Accuracy for analog levels between –20 to +55 dBmV.
Accuracy for digital levels between –20 to +50 dBmV.
Additional uncertainty of ±1.0 dB from 4 to 15 MHz.
Additional uncertainty of ±0.5 dB across –20 to +50°C.
4. MER Range declines as input levels decrease. Expected MER
Range at MIN LOCK Level of –15 dBmV is >30 dB MER.
5. Stated throughput is the max theoretical capability. Actual
performance may vary.
