    Apply Commands The APPLy command has 8 different types of outputs (Sine, Square, Ramp, Pulse, Noise, Triangle, DC, User). The command is the quickest, easiest way to output waveforms remotely. Frequency, amplitude and offset can be specified for each function. As only basic parameters can be set with the Apply command, other parameters use the instrument default values.
  • Page 29 When setting the amplitude, MINimum, Output MAXimum and DEFault can be used. The range Amplitude depends on the function being used and the output termination (50Ω or high impedance).
