Agilent Technologies E1441A AM:DEPTh?, AM:INTernal:FUNCtion?, AM:INTernal:FREQuency

AM:DEPTh?

[SOURce:]AM:DEPTh? [MINMAX] queries the modulation depth. Returns a value in percent.

AM:INTernal:FUNCtion

[SOURce:]AM:INTernal:FUNCtion SINSQUTRIRAMPNOISUSER selects the shape of the modulating waveform.

Used only when the internal modulation source is selected (AM:SOUR BOTH). You can use the noise function as the modulating waveform. However, you cannot use the noise function or dc volts as the carrier waveform. [ Stored in volatile memory ]

•*RST Condition: SINusoid

AM:INTernal:FUNCtion?

[SOURce:]AM:INTernal:FUNCtion? queries the shape of the internal modulating waveform. Returns “SIN”, “SQU”, “TRI”, “RAMP”, “NOIS”, or “USER”.

AM:INTernal:FREQuency

[SOURce:]AM:INTernal:FREQuency<frequency>MINMAX sets the frequency of the modulating waveform. Used only when the internal modulation source is selected (AM:SOUR BOTH). Select from 10 mHz to 20 kHz. MIN = 10 mHz. MAX

=20 kHz. [ Stored in volatile memory ]

•*RST Condition: 100 Hz

AM:INTernal:FREQuency?

[SOURce:]AM:INTernal:FREQuency? [MINMAX] queries the internal modulating frequency. Returns a value in hertz.

AM:SOURce

[SOURce:]AM:SOURce BOTHEXTernal selects the source of the modulating signal. The function generator will accept an internal modulating signal, an external modulating signal, or both. [ Stored in volatile memory ]
