Figure 3.6 Output Control with a WaveWiz Panel.

Selecting a

Standard

Function Shape

Standard (fixed) waveforms are built into the instrument’s program.

Nine standard function shapes are available: Sine, Triangle, Square,

Pulse, Ramp, Sinc, Exponential decaying pulse, Gaussian pulse, and

DC. Every time a standard function is selected

the coordinates for this

function are re-computed and placed in the waveform memory.

Therefore, there is a minimal delay after you select the function until

the output starts generating the waveform.

Use the following command to select a standard output function:

FUNCtion:SHAPe {SINusoid | TRIangle | SQUare PULSe |

RAMP | SINC | GAUS | EXP | DC}

The selected waveform is generated using the previously selected

frequency, amplitude, offset, and other relevant settings. The standard

waveform is available at the output connector only after the

FUNC:MODE:FIX command is selected.

The query:

FUNCtion:SHAPe?

queries the standard function shape and returns either SIN, TRI or
