Loop Test Translators Dual Channel • • • • • •
Ka and Ku Bands Synthesised LO Simultaneous Operation Local and Remote Ethernet Control Extremely Versatile Standard and Custom Options
The ALD series of Ka and Ku Band Loop Test Translators feature dual channel operation with the ability to introduce different transfer characteristics in each channel. In this way, one LTT instrument can be used in a variety of test applications for frequency conversions from Uplink (Tx) to Downlink (Rx) or to L-Band and from L-Band to Downlink (Rx). Each channel may have different values of Conversion Gain, Attenuation Range, Filtering Characteristics and LO Frequency. Instruments are essentially customised for the desired applications parameters.
