Spirent TAS 8250 - Cable Network Interference Emulator

• provides wideband channel emulation of the 50-to-860- MHz cable-television (CATV) downstream frequency band, as well as the 5-to-42-MHz upstream frequency band
• can generate additive impairments such as wideband noise, along with key cable-network characteristics such as amplitude tilt, network- filter emulation, and intermodulation distortion (IMD)
• allows users to independently control the level, frequency, and burst-timing characteristics of all impairment conditions in the upstream and downstream channels
