Agilent Technologies E1441A FSKey:FREQuency?, FSKey:INTernal:RATE?, FSKey:SOURce, Chapter

FSKey:FREQuency

[SOURce:]FSKey:FREQuency <frequency>MINMAX 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.

FSKey:FREQuency?

[SOURce:]FSKey:FREQuency? [MINMAX] queries the FSK “hop” frequency. Returns a value in hertz.

FSKey:INTernal:RATE

[SOURce:]FSKey:INTernal:RATE <rate in Hz>MINMAX 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

rate	numeric	10E-03 to 50E+03	Hz

Comments • The FSK rate is ignored when the external source is selected (FSK:SOUR EXT).

FSKey:INTernal:RATE?

[SOURce:]FSKey:INTernal:RATE? [MINMAX] queries the FSK rate. Returns a value in hertz.

FSKey:SOURce

[SOURce:]FSKey:SOURce INTernalEXTernal 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).
