– The function generator does not distinguish between upper- and lower-case
letters. Therefore, ARB_1 and arb_1 are the same name. All characters are
converted to upper case.
–Use the DATA:CAT? command to list the names of the five built-in waveforms
(non-volatile), “VOLATILE” if a waveform is currently downloaded to volatile
memory, and the names of any user-defined waveforms (non-volatile).
FUNCtion USER
FUNCtion?
Select the arbitrary waveform function and output the current arbitrary waveform.
When executed, this command outputs the arbitrary waveform currently selected
by the FUNC:USER command (see the previous page). The selected waveform is
output using the current frequency, amplitude, and offset voltage settings. The
FUNC? query returns “SIN”, “SQU”, “RAMP”, “PULS”, “NOIS”, “DC”, or “USER”.
–Use the APPLy command or the equivalent FREQ, VOLT, and VOLT:OFFS
commands to select the frequency, amplitude, and offset of the waveform
.
– 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-in “SINC” waveform does not use the full range of binary values between
±1 and therefore its maximum amplitude is 6.087 Vpp (into 50 ohms).
– If you select an arbitrary waveform as the modulating waveshape (“USER”), the
waveform is automatically limited to 4K points. Extra waveform points are
removed using decimation.
