Duplex Spacing definition
Duplex Spacing means the frequency separation between the transmit channel centre frequency and receive channel centre frequency of a station operating in a Duplex Frequency Mode (FDD).
Duplex Spacing. 45MHz, Modulation Type F3 +/- 12kHz for 100% @ ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ Chnl Sel: -60dB +/- 60kHz AMPS Audio Distortion: Less than 5% @ 1kHz, +/- 8kHz Deviation Audio Response: 6dB/octave pre-emphasis Tx 6dB/octave de-emphasis Rx Power Range: 6.77dBm nominal to 34.77dBm nominal in 8 power steps with 4dB separation between adjacent steps Audio Sensitivity: Greater than -116dBm (C-MSG weighted) @ 12dB SINAD SAT Sensitivity. Greater than -116dBm @ 12dB SINAD Signaling Sensitivity: Greater than -110dBm Input/Output Impedance: 50 ohms nominal Emissions: Conducted/Radiated/Spurious: Less than -60dB below carrier Hum & Noise: 32dB below 8kHz deviation @ 1kHz ________________________________________________________________________________ Telenetics Data Connector: RJ11 Modular To Internal Modem (Type III) To External Modem (Type I)
