The traditional engineering response to testing a wireless standard often involves selecting a box instrument with the closest specifications.
The RF frequencies of transmitting equipment are regulated by national governments and are different between global regions. Normally this requires different type or versions of a specific product for different markets. For test systems with multiple test requirements this often results in a different box for each measurement requirement. When the test requirements are uniform and no changing, this method may be sufficient, but it becomes cumbersome, and ultimately more expensive for testing RF devices.
Prevas Frequency Shifter recognizes the need for a dynamic setting of the frequencies. The example below show a two-path set up, and how the Frequency-band shifter is placed in-between the base station (DUT) and the simulator.
The architecture of the Frequency-band Shifter enables support for MIMO etc, and with a theoretical support for simultaneously shifting an unlimited amount of paths, all locked to the same reference.
The Frequency-band Shifter is primarily used in two areas of the communication industry;
The Frequency-band Shifter offer massive cost reductions when used in test-solutions based on traditional simulators like Aeroflex® TM 500 and unparalleled performance related to phase-noise and spurious if compared with build-it-yourself solutions. Last but not least, the solution saves a lot of space compared to similar functionality.
