Chapter 3
FSKey:FREQuency
[SOURce:]FSKey:FREQuency <frequency>|MIN|MAX sets the FSK “hop”
frequency. Select from 10 mHz to 15 MHz (100 kHz for triangle and ramp). The
default is 100 Hz.
MIN = 10 mHz. MAX = 15 MHz. The FSK frequency setting is
stored in volatile memory.
Parameters
FSKey:FREQuency?
[SOURce:]FSKey:FREQuency? [MIN|MAX] queries the FSK “hop” frequency.
Returns a value in hertz.
FSKey:INTernal:RATE
[SOURce:]FSKey:INTernal:RATE <rate in Hz>|MIN|MAX sets the rate at which the
output frequency “shifts” between the carrier and hop frequency (FSK:SOUR INT
only). Select from 10 mHz to 50 kHz. The default is 10 Hz.
MIN = 10 mHz. MAX =
50 kHz. The FSK internal rate setting is stored in volatile memory.
Parameters
Comments
• The FSK rate is ignored when the external source is selected (FSK:SOUR
EXT).
FSKey:INTernal:RATE?
[SOURce:]FSKey:INTernal:RATE? [MIN|MAX] queries the FSK rate. Returns a
value in hertz.
FSKey:SOURce
[SOURce:]FSKey:SOURce INTernal|EXTernal selects an internal or external FSK
source. The default is INT. [Stored in volatile memory ]
Comments • When the internal source is selected, the rate at which the output frequency
“shifts” between the carrier frequency and hop frequency is determined by the
FSK rate specified (FSK:INT:RATE).
