VOLATILE

DATA VOLATILE, <value>, <value>,. . . is used to download floating-pointvalues between -1and +1 into volatile memory. You can download between 8 and 16,000 points per waveform.

Comments The values -1 and +1 correspond to the peak values of the waveform.

For example, if you set the amplitude to 10 Vpp, “-1” corresponds to -5 volts and “+1” corresponds to +5 volts.

The maximum amplitude will be limited if the data points do not span the full range of the output DAC (Digital-to-Analog Converter). For example, the built-inSINC” waveform does not use the full range of values between ±1 and therefore its maximum amplitude is 6.084 Vpp (into 50 ohms).

Downloading floating-point values (using DATA VOLATILE) is slower than downloading binary values (using DATA:DAC VOLATILE) but is more convenient when using trigonometric functions which return values between -1 and +1.

The DATA VOLATILE command overwrites the previous waveform in VOLATILE memory (no error is generated). Use the DATA:COPY command to copy the waveform to non-volatile memory.

Up to four user-defined waveforms can be stored in non-volatile memory. Use the DATA:DEL command to delete the waveform in VOLATILE memory or any of the four user-defined waveforms in non-volatile memory. Use the DATA:CAT? command to list all waveforms currently stored in volatile and non-volatile memory (and the built-in waveforms).

After downloading the waveform data to memory, use the FUNC:USER command to choose the active waveform and the FUNC:SHAP USER command to output it.
