SMU200A Vector Signal Generator 35

Digital standards with R&S

WinIQSIM2™

(for the R&S

SMU-B9/-B10/-B11 ARB)

At least one I/Q baseband generator (R&S

SMU-B9/-B10/-B11 options) must be installed. If two I/Q baseband generators are installed

and two waveforms of the same standard (e.g. GSM/EDGE) are to be output simultaneously, two corresponding software options must

also be installed (in this case R&S

SMU-K240). If only one R&S

SMU-K240 is installed and GSM/EDGE waveforms are played in one

I/Q baseband generator, the other I/Q baseband generator is disabled for GSM/EDGE waveforms. However, a software option is not

tied to a specific I/Q baseband generator.

The R&S

SMU-B9/-B10/-B11 or R&S

SMU-B17 option is required to generate input signals for the fading simulator.

All frequency and time settings are coupled to the internal reference frequency.

At least one R&S

SMU-B14 fading simulator must be installed. If both the R&S

SMU-B14 and the R&S

SMU-B15 are installed (signal

paths A and B), dynamic fading and enhanced resolution can be used either on signal path A or B with one R&S

SMU-K71 option. For

dynamic fading and enhanced resolution to be used on signal paths A and B simultaneously, two R&S

SMU-K71 must be installed.
