The MUX-2A-QAM is designed to allow CATV operators to multiplex two input sources in ASI format to a single QAM output channel for delivery over a standard coaxial distribution network. The MUX-2A-QAM accepts up to two (2) ASI inputs and aggregates them onto one QAM RF output in the 54-864 MHz range. The MUX-2A-QAM provides the capability to filter program streams and to assign major/minor or a single 4-digit channel number to each. The MUX-2A-QAM also provides Emergency Alert System (EAS) program switching through a third ASI input and terminal block contacts. The EAS input source can be shared among multiple MUX-2A-QAM units by looping it from one to another unit without the need for external splitting and amplification.

  • Supports MPEG-2 Transport Stream Tables: PAT, PMT, MGT, RRT, STT, & VCT
  • Re-maps duplicate PIDs, Program Numbers, and Minor Channel Numbers
  • Allows sharing of the EAS input source among multiple units
  • User-defined major/minor or 4-digit CATV virtual channels
  • User-defined channel names
  • EAS input replaces up to 12 program streams
  • Supports PID filtering & PSIP re-assignment
  • Provides QAM 256 Output at 38.8 Mbps
  • Accepts ASI input as EAS input source
  • User-defined QAM Output Parameters
  • Maintains MPEG-2 mapping
ASI:: 2x BNC Female
Emergency Alert System (EAS):: 1x BNC Female
Standard:: DVB-ASI; EN 50083-9 (MPTS/SPTS)
Transport Range:: 270 Mbps
Level Range:: 720 to 950 mVpp (800 mVpp nominal)
Impedance:: 75 ohm
Emergency Alert System
Standard:: DVB-ASI; EN 50083-9 (SPTS)
Transport Rate:: Single program at 3 Mbps (based upon 12 programs using 256 QAM output). Higher data rates can be used with a lower number of output programs as to not exceed the maximum allowable bit rate on the QAM output channel. NOTE: The EAS program (when triggered) is multiplied by the number of output programs. A 3 Mbps EAS video file on 12 programs therefore equals 36 Mbps. This bit rate is acceptable when using 256 QAM that has a maximum of 38.8 Mbps.
Level Range:: 720 to 950 mVpp (800 mVpp nominal)
Impedance:: 75 ohm
Connector:: 1x “F” Female
QAM Modulation Modes:: 16, 32, 64, 128, 256, 512, and 1024
DVB Symbol Rate:: Variable; 1 to 7 MSymbols/sec (MBaud)
Frequency Range:: 54 to 864 MHz
QAM Tuning: CATV Ch. 2-135 (STD, HRC, IRC)
RF Level:: +45 dBmV
RF Level LCD Screen Error:: ± 2 dB
RF Level Adjustment Range:: 35 to 45 dBmV
Frequency Stability:: ± 10 kHz over 32 to 122 °F (0 to 50 °C)
Frequency Tolerance:: ± 0.5 kHz @ 77 °F (25 °C)
Amplitude Flatness:: ± 0.25 dB (over 6 MHz channel)
Phase Noise:: -98 dBc (@ 10 kHz)
Spurious:: -60 dBc
