[:SOURce]:RADio:ARB:GENerate:SINE ["<file_name>"][,<osr>],[<scale>],

[I|Q|IQ][<phasedeg>]

This command creates a sine wave waveform file and saves it in the signal generator’s volatile

waveform memory (WFM1).

"<file_name>" This variable names the file used to save the generated sine wave data.

<osr> This variable sets the oversample ratio, which must be an even number and 4.

The <osr> variable is expressed in samples. If the oversample ratio is < 60 (the

minimum number of samples or I/Q points required for a waveform), multiple

waveform periods are generated to create a waveform file with 60 samples. The

number of periods created is 60  <osr> (quotient will round up to an integer

value). A waveform with an oversample ratio  60 has one period.

<scale> This variable sets the scale factor for the waveform. The scale factor is a real

number from zero to one.

I|Q|IQ Selects I, Q, or I and Q paths for the waveform data. Sinewave data is generated

and applied to the I path if the I path is selected; Q data are set to zeros. Sine

data is generated and applied to the Q path if the Q path is selected; I data are

set to zeros. If the I and Q paths are selected, sinewave data are applied to the I

and Q paths.

<phasedeg> Selects the phase angle of the waveform data. Sinewave data is generated and the

phase angle in degrees is applied to the sine wave.

Example

:RAD:ARB:GEN:SINE "Sine_Wave",60,.5,IQ

The preceding example generates an I/Q sine wave and saves the data to a file named Sine_Wave.

The oversampling ratio is 60, the scaling is set for 50%, and the data is applied to both the I and Q

paths.

The signal generator’s baseband option and available baseband memory determine the maximum

number of samples for the waveform.
