[:SOURce]:DM:GFSK:DSLope ON | OFF
The command specifies the level reduction for the modulation.
ON The rise and fall time of the level reduction correspond to DECT power ramping.
OFF Command DM:DATA:ALEVel:MODE specifies the level reduction.
Example: :SOUR:DM:GFSK:DSL ON *RST value is OFF
[:SOURce]:DM:GFSK:POLarity NORMal | INVerted
The command specifies the polarity of the modulation.
NORMal A "1" from the data source results in a positive deviation
INVerted A "1" from the data source results in a negative deviation
Example: :SOUR:DM:GMSK:POL INV *RST value is NORMal
[:SOURce]:DM:QPSK
The commands to set the data source for the digital type of modulation QPSK ( Quad P
hase Shift
Keying) are under this node. The key word :DQPSk is also accepted..
[:SOURce]:DM:QPSK:STANdard NADC | PDC | TFTS | TETRa | APCO | MSAT | INMarsat
This short-form command sets parameters shown in the table to the values specified by standards
(cf. table). The command is an abbreviation of the commands listed in the table. Hence it neither
has a query form nor an *RST value.
