Parameters:
<Source> ZERO | ONE | PRBS | PATTern | DLISt
ZERO|ONE
An internally generated 0 or 1 data sequence is used.
PRBS
The pseudo-random sequence generator is used as the data
source. The length of the random sequence is defined with the
command
SOURce:BB:DM:PRBS
.
PATTern
Internally generated data with a fixed pattern is used. The data
pattern is dafined using command
SOURce:BB:DM:PATTern
.
DLISt
Data from the selected data list is used.
*RST:
PRBS
Example:
BB:DM:SOUR DLIS
BB:DM:DLIS:SEL 'test'
// the data list test.dm_iqd is used
Manual operation: See "Data Source" on page 353
[:SOURce<hw>]:BB:DM:SRATe <SRate>
Sets the symbol rate. The value range is dependent on the selected modulation type.
On changing to an FSK modulation type, excessively high values are automatically
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:
400 to depends on hardware
Increment: 0.001
*RST:
270833.333
Default unit: Hz
Example: BB:DM:SRAT 10 MHz
sets a symbol rate of 10 MHz.
Manual operation: See "Symbol Rate" on page 356
[:SOURce<hw>]:BB:DM:STANdard <Standard>
Selects the standard.
