Interpreting Chart 1:
The matrix above gives both the input and output ranges in dBm for each CNG model with each of the standard options. There are two sets of ranges, one is the ideal range for highest accuracy and the other is the total or functional range. The reason for the two sets is that the very complex signals such as 256 QAM, Faded CDMA base station receive signals, and 7/8 coded QPSK have a very high peak factor and large time constant. The built-in power meter can accurately measure these, but over a narrower dynamic range than less complex signals. The built-in power meter does have powerful signal processing and curve fitting algorithms to accurately measure complex signals. Micronetics chose these limited ideal ranges based on extensive data taken over many modulation schemes and data rates. We chose to be conservative because the CNG instruments are universal to any modulation type, the output corresponds to the input signal amplitude range less any insertion loss from input to output. If the carrier signal attenuator option is ordered, The output signal range corresponds to the 0 dB attenuation setting of the carrier attenuator. Obviously the overall output range is much greater corresponding to the range at the 0 dB setting plus 99 dB.
