FREQuency:STARt?

Parameters

Parameter Name	Parameter Type	Range of Values	Default Units

frequency	numeric	10E-03 to 15E+06	Hz

FREQuency:STARt?

[SOURce:]FREQuency:STARt? [MINMAX] queries the start frequency. Returns a value in hertz.

FREQuency:STOP

[SOURce:]FREQuency:STOP <frequency>MINMAX sets the stop frequency. Select from 10 mHz to 15 MHz (100 kHz for triangle and ramp). The sweep is phase continuous over the full frequency range. The default is 1 kHz. MIN = 10 mHz. MAX

=15 MHz. [ Stored in volatile memory ]

Frequency-Shift Keying (FSK) Commands

Use the APPLy command or the equivalent FUNC:SHAP, FREQ, VOLT, and VOLT:OFFS commands to configure the carrier waveform. Set the carrier frequency between 100 ∝Hz and 15 MHz (100 kHz maximum for triangle and ramp). The default is 1 kHz.
