Rohde & Schwarz SME02 - Source:DM Subsystem

3.6.11.3 SOURce:DM Subsystem
In this subsystem, the types of digital modulation are checked. A difference is made between basic
modulations (GMSK, GFSK, QPSK, FSK, 4FSK and FFSK) and complex modulations (ERMES, FLEX,
POCSAG). The common characteristics of all basic modulations are set under node [:BASic], the
common characteristics of all complex modulations under :COMPlex. An external input, an internal
pseudo-random sequence generator and an internal data generator are available as data source for the
basic modulations.
Note: The signal generator SME42 (Id No. 1038.6002.42) is a special model for ERMES, FLEX,
FLEX-TD and POCSAG. The options SME-B11 (DM coder), SME-B12 (DM expanded memory),
SME-B41 (FLEX protocol) and SME-B42 (POCSAG protocol) have been integrated in the
SME42 as standard.
Only the command MGRoup? and the commands of node SOURce:DM:COMPlex are available
when using the SME42.
