The instruments feature up to 121 dB of attenuation with selectable step values and a programmable attenuation sweep function that enables user-defined sweep time, attenuation values and number of cycles.
The new LXI-compliant instruments are ideal for R&D and manufacturing engineers in wireless communications tasked with designing, validating, and manufacturing WiMAX and WLAN components, as well as for mobile handset base transceiver station (BTS) handover test.
It provides ease-of-use in benchtop applications and greater efficiency and throughput in ATE testing applications. The attenuation sweep function allows the user to set the desired start/stop attenuation, step size, dwell time and sweep time of each measurement based on specific application requirements. This capability is especially useful for simulating BTS fading in mobile handset handover test.
The control units feature less than 0.03 dB insertion loss repeatability per section over their entire 5-million life cycle. As a result, users realise a significant reduction in the cost of ownership of the test equipment. The 0.03 dB insertion loss repeatability reduces the source of random errors which, in turn, improves measurement accuracy over the entire operating life of the instrument.
LXI Class C compliance provides LAN connectivity, making it easy to remotely control and trigger the instruments through a graphical web interface. The multiple connectivity capability also includes GPIB and USB, so the attenuation control unit can be quickly set up and easily integrated into any benchtop or ATE solution.
