Remote Control Commands
SOURce:BB:DM Subsystem
If the coding that is set (:BB:DM:COD) is not possible with the modulation type selected,
it is automatically set to OFF (:BB:DM:COD OFF).
When a standard is selected (:DM:STAN), the modulation type is set to the default value.
Parameters:
ASK | BPSK | P2DBpsk | QPSK | QPSK45 | OQPSk | P4QPsk |
P4DQpsk | PSK8 | P8D8psk | P8EDge | QAM16 | QAM32 |
QAM64 | QAM256 | QAM1024 | MSK | FSK2 | FSK4 | USER |
FSKVar | QAM128 | QEDGe | QAM16EDge | QAM32EDge |
AQPSk
Example:
*RST:
MSK
BB:DM:FORM QPSK
selects modulation type QPSK.
Manual operation: See "Modulation Type - Digital Modulation" on page 69
[:SOURce]:BB:DM:FSK:DEViation
The command sets the frequency deviation when FSK modulation is selected. The range
of values depends on the symbol rate that is set (see data sheet) and the maximum
deviation is 10 MHz.
If the symbol rate that is set exceeds the maximum possible value for the chosen frequency
deviation, it is suitably adapted (:BB:DM:SRAT).
Parameters:
Example:
float
Range: 1 to 40E6
Increment: 0.5
*RST: 135416.5
BB:DM:FORM FSK
selects FSK modulation.
BB:DM:FSK:DEV 10 MHz
sets the frequency deviation to 10 MHz.
Manual operation: See "FSK Deviation - Digital Modulation" on page 70
[:SOURce]:BB:DM:FSK:VARiable:SYMBol:DEViation
The command sets the deviation of the selected symbol for variable FSK modulation
mode.
Suffix:
.
0 .. 16
The number of symbols (and therefore the suffix range) depends
on the selected FSK modulation type.
