IQ data streaming - sample rate conflict if wideband SMW200A is connected to SMBV100A

Question

By using its IQ interfaces, generators like the R&S®SMBV100B can be used to extend the RF output capabilities of an R&S®SMW200A.

However, since the R&S®SMBV100A has a maximum sample rate of 100 MHz, it’s not compatible with a wideband R&S®SMW200A which has a fixed sample rate of 250 MHz. Both units can be connected and IQ data streaming is working, but due to sample rate mismatch the output signal is distorted.

Answer

The solution would be to use an R&S®SMW200A without wideband option B9 or R&S®SMBV100B which supports up to 250 MS/s.
