Key Facts

CMU IQ/IF Interface Opens the Door to New Applications

An IQ/IF interface with separate access to the IF/IQ signal transmitter and receiver paths is now available for the R&S®CMU200 as Option R&S®CMU-B17, adding intriguing new functions which are unique for mobile phone testing, and for the first time lets the R&S®CMU address a new application for mobile phone chipset testing.

In combination with fading simulators R&S ABFS or R&S SMIQ test a mobile phone under fading conditions

With fading simulator setup, conduct receiver Bit Error Rate (BER) tests under fading conditions on the downlink channel (R&S®SMIQ must include the IQ fading simulator, Option R&S®SMIQ-B14).

Test mobile phone chipsets

Most mobile phone chipsets comprise an RF chip and a baseband chip that communicate with each other via an analog IQ interface. Use the R&S®CMU-B17 IQ-interface to access the two chips. Option B17 can generate complex IQ signals to meet the relevant standards, even signals originating from a real signaling sequence.
