PurposeSets the RMS voltage of the DDS sine-wave synthesizer.

For a sine wave, Vrms = Vpeak / √2 = (Vpk to pk)/(2×√2). The MAX RMS voltage varies by potentiostat and is 3.62 V (5.12 V Peak) on a PCI4 or Series G family Potentiostat. PC5 family Potentiostats have a 1.448 V RMS maximum (2.048 V Peak). Requested voltages which are higher than the maximum value are limited to the maximum value.

Usage: Result = Pstat.DDSAmpl()

  Ampl REAL Requested RMS amplitude (volts)
  Result REAL Resulting RMS amplitude as set.
