SMIQSOURce:DM Subsystem[:SOURce]:DM:FSK:DEViation 100 kHz to 2.5 MHzThe command sets the deviation for FSK (only for DM:FORmat FSK2, FSK4 and GFSK).Example: :SOUR:DM:FSK:DEV 9 kHz *RST value is 4.5 kHz[:SOURce]:DM:SRATe 1kHz to 7 MHzThe command sets the symbol rate.Example: :SOUR:DM:SRAT 200 kHz *RST value is 24.3 kHz[:SOURce]:DM:FILTerThe filter selection commands are under this node.[:SOURce]:DM:FILTer:TYPE SCOSine | COSine | GAUSs | LGAuss | BESS1 | BESS2 | IS95 | EIS95 |APCO | TETRa | WCDMa | RECTangle | SPHase | USERThe command selects the type of filter.BESS1 BESSEL B*T 1.25BESS2 BESSEL B*T 2.50EIS95 IS-95+EQUALIZERAPCO filter according to standard APCO modulation C4FMUSER The filter list selected with DM:FLIS:SEL... and defined via DM:FLIS:DATA...is used.Example: :SOUR:DM:FILT:TYPE GAUS *RST value is SCOS[:SOURce]:DM:FILTer:PARameter 0.1 to 1.0The command sets the filter parameter (Roff Off or BxT rate).Example: :SOUR:DM:FILT:PAR 1 *RST value is 0.35[:SOURce]:DM:FILTer:MODE LACP | LEVMThe command selects the filter mode.Example: :SOUR:DM:FILT:MODE LEVM *RST value is LACP[:SOURce]:DM:CODing OFF | GSM | NADC | PDC | PHS | TETRa | TFTS | PWT | INMarsat | DIFF |DPHS | DGRay | APCO25 | VDLThe command selects the modulation coding (standard) .DPHS PHASE DIFFDGRay DIFF + DGRAYExample: :SOUR:DM:COD NADC *RST value is OFF[:SOURce]:DM:CLOCkThe commands for setting the data clock are under this node.[:SOURce]:DM:CLOCk:SOURce INTernal | EXTernal | COUPledThe command selects the source for the clock of the digital modulation.INTernal The internal clock generator is used.EXTernal The clock is fed externally.COUPled The clock comes from the same source as the data. Selection is determined by:DM:SOURce.Example: :SOUR:DM:CLOC:SOUR INT *RST value is COUPled1125.5555.03 3.75 E-9
