FSK Type
(Variable FSK only)
Selects the FSK modulation type for selection "Variable FSK".
You may choose from 4FSK, 8FSK and 16FSK.
Remote command:
[:SOURce<hw>]:BB:DM:FSK:VARiable:TYPE
on page 650
Deviation xxxx
(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.
Remote command:
[:SOURce<hw>]:BB:DM:FSK:VARiable:SYMBol<ch0>:DEViation
on page 650
Modulation Delay
(Data Source ext serial and ext parallel 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
corresponding peak I/Q value (associated with this data item) on the I/Q connectors.
Remote command:
[:SOURce<hw>]:BB:DM:MDELay?
on page 650
Current Modulation Type
Displays the currently selected modulation type together with its associated mapping.
Remote 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
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.
Remote command:
[:SOURce<hw>]:BB:DM:SWITching:STATe
on page 633
Source Mod - CW
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.
The internal signal can be output on one of the user interfaces.
"External" The control signal on the CW pin of the AUX I/O connector is used.
