Input Frequency Range: 27500 - 31500MHz Output Frequency Range: 800 - 2600MHz
The LNI series (Low Noise Injection) Test Loop Translator Systems (TLT's) provide the satellite communications engineer with a complete and versatile set up for off-satellite loop back testing of the transmit (Tx) signal to L-band combined with the ability to inject white symmetrical gaussian noise for simultaneous receiver and modem testing.
Input attenuation is controlled over a 60dB range in 0.5dB steps and local oscillator (LO) frequency in 25MHz steps. The white noise level is variable by up to 60dB in 0.25dB steps with an additional mute facility.
Local control of both the TLT and noise injection is done via front panel controls or remotely via Ethernet with an easy-to-use GUI. Frequency stability of the LO is derived from either the internal OCXO or from a system 10MHz reference.
