5 Application Examples
This chapter covers some application examples. The test setups show the R&S
EX-IQ-
BOX controlled by R&S
DigIConf. Applications with User Defined Interface transmission
protocols also support the direct control of the R&S
EX-IQ-BOX by R&S Instruments.
Standardized interface protocols always require the configuration by R&S
DigIConf.

An R&S signal generator together with the R&S
EX-IQ-BOX provides digital baseband
signals for all important mobile radio and wireless digital standards such as EUTRA/LTE,
3GPP, HSPA, GSM/EDGE, WiMAX IEEE 802.16 and WLAN IEEE 802.11n. All signal
generator functions are also available for generating digital baseband signals, plus all
signal processing functions to yield effects such as fading, AWGN or I/Q impairments.
This allows measurements on baseband receiver chips to be performed accurately and
