[:SOURce<hw>]:BB:DM:SRATe <SRate>
The command sets the symbol rate. The value range is dependent on the selected mod-
ulation type. On changing to an FSK modulation type, excessively high values are auto-
matically limited to the maximum value that can be set for FSK (see data sheet). The
symbol rate can be entered in Hz/kHz/MHz or Symb/s / kSymb/s and MSymb/s.
When a standard is selected (DM:STANdard), the symbol rate is automatically set to the
appropriate default value.
The value range is dependent on the selected modulation type (:BB:DM:FORM). When a
standard is selected (:BB:DM:STAN), the symbol rate is set to the default value.
Parameters:
<SRate> float
Range: 400Hz to 15MHz (FSK) / 25 MHz
Increment: 0.001Hz
*RST: 270833kHz
Default unit: Hz
Example:
BB:DM:SRAT 10 MHz
sets a symbol rate of 10 MHz.
[:SOURce<hw>]:BB:DM:STANdard <Standard>
The command selects the standard. After selection, modulation parameters "Modulation
Type" (:BB:DM:FORMat), "Symbol Rate" (:BB:DM:SRATe), "Filter"
(:BB:DM:FILTer:TYPE and :BB:DM:FILTer:PARameter:...) and "Coding"
(:BB:DM:CODing) are automatically set in accordance with the standard. The USER
parameter cannot be set. A query returns this value if a user-defined Custom Dig Mod
setting was loaded or if one of the associated settings was changed subsequent to the
selection of a standard. The user defined settings are stored and loaded with com-
mands :BB:DM:STAN:ULIS:... (see "DM Lists" on page 572).
Parameters:
<Standard> USER | BLUetooth | DECT | ETC | GSM | GSMEdge | NADC |
PDC | PHS | TETRa | W3GPp | TDSCdma | CFORward |
CREVerse | WORLdspace | TFTS | APCOPH1C4fm |
APCOPH1CQpsk | APCOPH2HCpm | APCOPH2HDQpsk |
APCOPH2HD8PSKW | APCOPH2HD8PSKN | APCOPH1Lsm |
APCOPH1Wcqpsk
*RST: GSM
Example:
BB:DM:STAN DECT
selects digital modulation according to the DECT standard.
[:SOURce<hw>]:BB:DM:STATe <State>
The command enables or disables digital modulation. Switching on digital modulation
turns off all the other digital standards.
