[:SOURce]:DM:GFSK:STANdard DECT | CT2 | CT3
This short-form command sets the parameters shown in the table to the values specified by the
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.

Example: :SOUR:DM:GFSK:STAN DECT
[:SOURce]:DM:GFSK:BRATe 10 to 585 kb/s and 640 to 1170 kb/s
The command sets the bit rate for the modulation in bits per second. With setting FILTer 0.5 and
DEViation 14.0 kHz or 25.2 kHz the range is 0.05...90 kb/s
Example: :SOUR:DM:GFSK:BRAT 1122 kb/s *RST value is 1170 kb/s
[:SOURce]:DM:GFSK:DEViation 14 |14.4 |18 |20.0 |25.2 |160 |180 |202 |259 |288 |317 |403 kHz
The command sets the frequency deviation of the modulation. The value of
:SOURce:DM:GMSK:DEViation is adapted if necessary in order to achieve a valid setting.
Valid settings are: DEViation FILTer DEViation FILTer
14 kHz 0.5 180 kHz 0.5
14.4 kHz 0.7 202 kHz 0.5
18 kHz 0.5 259 kHz 0.5
20.0 kHz 0.5 288 kHz 0.4, 0.5, 0.6
25.2 kHz 0.4, 0.5 317 kHz 0.5
160 kHz 0.5 403 kHz 0.5
Example: :SOUR:DM:GMSK:DEV 288E3 *RST value is 288 kHz
[:SOURce]:DM:GFSK:FILTer 0.4 | 0.5 | 0.6 | 0.7
The command specifies B x T of the filter used. The value of :SOURce:DM:GFSK:DEViation is
adapted if necessary in order to achieve a valid setting
Valid settings are: FILTer DEViation
0.4 25.2 kHz, 288 kHz
0.5 14 kHz, 18 kHz, 20.0 kHz, 25.2 kHz, 160 kHz, 180 kHz,
202 kHz, 259 kHz, 288 kHz, 317 kHz, 403 kHz
0.6 288 kHz
0.7 14.4 kHz *RST value is 0.5
Example: :SOUR:DM:GFSK:FILT 0.4
