FSK Type - Digital Modulation
(Variable FSK only)
Selects the FSK modulation type for selection "Variable FSK".
You may choose from 4FSK, 8FSK and 16FSK.
SCPI command:
[:SOURce<hw>]:BB:DM:FSK:VARiable:TYPE on page 568
Deviation xxxx - Digital Modulation
(Variable FSK only)
Set the deviation of the associated symbol. The number of symbols depends on the
selected modulation type. The value of each symbol is indicated in binary format.
SCPI command:
[:SOURce<hw>]:BB:DM:FSK:VARiable:SYMBol<ch>:DEViation on page 568
Modulation Delay - Digital Modulation
(Data Source ext serial only)
Displays the digital modulation delay from the data input to the I/Q output.
The value is displayed only if an external synchronous data source is selected. In this
case the value represents the delay between the active clock edge for data and the cor-
responding peak I/Q value (associated with this data item) on the I/Q connectors.
SCPI command:
[:SOURce<hw>]:BB:DM:MDELay on page 569
Current Modulation Type - Digital Modulation
Displays the currently selected modulation type together with its associated mapping.
SCPI command:
n.a.
Modulation - CW Switching
The "Modulation <=> CW Switching" section is used to enable switching the signal
between modulated and unmodulated.
State Mod - CW - Digital Modulation
Enables switching between a modulated and an unmodulated signal.
Switching is carried out by a control signal (CW) that is defined internally in the control
list or supplied from an external source via a user-defined input.
SCPI command:
[:SOURce<hw>]:BB:DM:SWITching:STATe on page 552
Source Mod - CW - Digital Modulation
Selects the CW control signal for switching between a modulated and an unmodulated
signal.
"Internal"
The CW signal in the control list is used for the control.
SCPI command:
[:SOURce<hw>]:BB:DM:SWITching:SOURce on page 552
