  • Legacy Transmission Products

    Enginuity Communications

    The DST2496I2 is an intelligent 200-Mechanics sized active interface between a 4-wire facility and a 2/4-wire data modem. The DST2496I2 supports 3 or 4 tone equalization alignment, multiple loopback activation tones, and drop-side transmit and receive signal levels selectable through remote tone provisioning. Facility impedance and 2 or 4-wire drop can be selected through on-board manual switches. DST2496I2 also allows the user to set the drop-side signal levels for Data or FAA applications, select the loopback activation tone, and manually activate signal loopback from the front panel pushbutton switch. The DST2496I2 can be powered from a local -48Vdc/24Vac source or from the span sealing current. The DST2496I2 also has external sealing current connections for supplying or terminating applications.

  • Drone Payload Satellite Simulator

    AtlanTecRF

    AtlanTecRF has introduced a new light-weight, rugged and compact Drone Payload Satellite Simulator. The unique simulator is capable of providing a transmit (Tx) to receive (Rx) loop-back for compact and mobile satellite communications systems testing without the need for cable connections. AtlanTecRF standard high performance LTT microwave circuits, have been configured for installation along with circularly polarised Ka-Band antennas and a rechargeable battery power pack into a specially designed and weatherproof housing capable of being carried by a moderately sized hovering drone. The drone is then flown into the line of sight of the satcom system antenna providing the loop-back and facilitating system/antenna testing and calibration without the need to go live on the satellite. Test methods using other satellite simulator models can involve mounting the simulator test instrument on a mast or ‘cherry picker’ to intercept the satcom system's line of sight. But such an arrangement can give rise to test site clutter and inconvenience in some circumstances. The Drone Payload avoids this scenario and also has the advantage of being able to provide the loop-back from heights above the ground which would be simply impractical by other methods.
