  • Ka Bands and Ku Bands
  • Synthesised LO - Ethernet Control
  • Simulates Satellite Link
  • All Frequency Combinations
  • Tx-Rx, Tx-L and L-Rx Conversions
  • Local and Remote Ethernet Control for LO Frequency and Signal Attenuation
  • Internal 10MHz Reference
  • Standard and Custom Options

The LBP series of Ka Band and Ku Band Portable, Battery Powered Loop Test Translators (LTT) feature Synthesised Variable Frequency Local Oscillators (LOs) to provide the user with the most versatile and comprehensive operating configurations for translation of uplink (Tx) frequencies to either downlink (Rx) frequencies or to L-Band, and for L- Band to downlink (Rx)

These Translators simulate the satellite transponder frequency conversion for system alignment and continuous quality monitoring.

Both the LO frequency and through path attenuation can be controlled either locally with direct readout on the front panel LCD or remotely via Ethernet with a virtual control panel.

The LTT contains a 12V, 14AH rechargeable battery and is supplied with an external battery charger which connects to the unit via a 3 pin XLR connector and is powered from a 100-240V, 50-60Hz A/C supply.
