Equipment & Components for the Satcom & Microwave/RF Industries

Ka Band - Satellite Simulator

  • Cable-less RF Test Solution
  • Dual Polarity
  • Ka Band (Ku and DBS available)
  • Totally Portable
  • Battery Powered
  • Self Contained Operation

The LSS series of Satellite Simulators enable RF testing of mobile satellite communications systems without the need for cabling and with true portability for optimum equipment location.

These simulators are fitted with dual polarised horn antennas in both the uplink and downlink bands and for each frequency conversion there is a separate attenuator providing adjustment of signal levels to accommodate receiver sensitivity and range distance.

Power is provided by a 12V, 14AH internal battery for 24 hour operation and each instrument is supplied with an external charger, although there is also the option for an internal charger for direct 100-240V 50/60Hz input. Self contained operation is completed with the internal high stability 10MHz OCXO reference.

The product described is for Ka band operation and similar units are available for Ku and DBS bands.
