Overall I think it would be simpler to increase the amplitude of the existing carrier frequency rather than build a device to generate a new one. An Arbitrary waveform can be generated by superimposing either noise or DC offset voltages upon a standard signal or by introducing gaps between waveform bursts or by performing various modulations (such as amplitude, frequency, phase modulations) on a standard signal. It's a memory-time tradeoff. Without the two 9v batteries, the amp behaves strangely, and may "cut off" the higher and lower parts of waveforms, which would be sad. Consider:sine(x)(pi/6)which would be the correct resolution to use but, since this resolution divides evenly into 2pi, but not into p/2 our waveform will look strange, because at no point is the output equal to the minimum or the maximum of the function, which is to say something near to 0x00 or 0xFF! The Benchtop has an easy-to-use front panel with a large screen and keyboard. The compact form size enables up to 4 generator output channels and 2 digitizer input channels to occupy only 3 PXI slots. That function must of course test if r18=0x00, and if so branch back to the first function.I'll end this tutorial with a few clues on how to cleverly use this device:-Use proper timer functions to accurately create low frequency waveforms.
