HSM-1000
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.
