Example: BB:DM:COD GRAY
selects GRAY coding. This coding is valid for all modulation
types.
Manual operation: See "Coding" on page 345
[:SOURce<hw>]:BB:DM:FORMat <Format>
Selects the modulation type.
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:
<Format> 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 | QAM4096
*RST:
MSK
Example: BB:DM:FORM QPSK
selects modulation type QPSK.
Manual operation: See "Modulation Type" on page 346
[:SOURce<hw>]:BB:DM:FSK:DEViation <Deviation>
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 fre-
quency deviation, it is suitably adapted (
:BB:DM:SRAT
).
Parameters:
<Deviation> float
Range:
1 to 40E6
Increment: 0.5
*RST:
135416.5
Example: 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" on page 346
