4.13.1.8.5 FM SOURce
This command selects the FM modulation source as either internal (then the above settings are effective) or external (and then the
external waveform determines deviation, shape and frequency of modulation).
Arguments
Type: Character
Options: INTernal, EXTernal
Command Type: Setting or Query
Setting
Syntax: [:SOURce:] FM:SOURce<ws><option>
Examples: FM:SOUR INT
FM:SOUR EXT
Query
Syntax: [:SOURce]:FM:SOURce?
Response: INT|EXT
4.13.1.9 FSK modulation
The following commands control the FSK modulation:
4.13.1.9.1 FSK STATe
This command activates or deactivates FSK modulation:Arguments
Type: Boolean
Command Type: Setting or Query
Setting
Syntax: [:SOURce:]FSK[:STATe]<ws>ON|1|OFF|0
Examples: FSK:STAT ON
FM OFF
Query
Syntax: [:SOURce:]FSK[:STATe]?
Response: 0|1
4.13.1.9.2 FSK LOWFrequency
This command sets the lower of the two frequencies used in FSK modulation.
Arguments
Type: Numeric.
Units: MHz, KHz, Hz (default)
Range: The whole frequency range of the current function.
Rounding: The value is rounded to 4 digits.
Command Type: Setting or Query
Setting
Syntax: [:SOURce:]FSK:LOWFrequency<ws><frequency>[units]
