HSM1000 PathTrak High Speed Modem
The HSM1000 Stealth Modem is used in combination with the
PathTrak Headend Control Unit (HCU) or the Phasor DSP565 to transport data from
the PathTrak to the Stealth SDA-5000 / 4040D field meters.
The HSM1000 is a required component of the Field View feature,
which allows the network technician to observe real-time headend spectrum graphs
at field locations using the SDA.
Data is transmitted to the SDA-5000 / 4040D via an FSK modulated
(100 kHz) telemetry carrier. The telemetry can be inserted in any unoccupied
bandwidth on the forward path up to 1000 MHz, with an adjustable output level
from +20 to +50 dBmV. All telemetry parameters are programmable via PathTrak or
Phasor software.
The HSM1000 connection with the PathTrak HCU or Phasor DSP565 is
accomplished via standard RS232 communication, and a rear panel RF output port
allows for easy coupling to the cable systems forward path. The universal power
supply adapts to all international standards with an input voltage range of
85-264 VAC / 47-440 Hz.
