To Set the Sampling Rate
In TrueArb output mode, users can set the sampling rate (the output points-
per-second) or frequency of the arbitrary waveform. The instrument outputs an
arbitrary waveform point-by-point with the current sampling rate.
Press Waveforms → Page 1/2 → Arb → TrueArb → SRate, to set the sampling
rate parameter. When changing parameter, if the new value is valid, the value
will be set. Otherwise, the nearest valid value will be set.
To Set the Interpolation Mode
In TrueArb output mode, the T3AFG supports two interpolation modes of
including 0-order hold and Linear. Users can set the parameter by pressing
Interpolation in the operation menu. Figure 2-19 shows the output waveform
comparison of a 32-point sinusoidal arbitrary wave with "0-order hold"
interpolation and "linear" interpolation.
