The GX1110 is a high performance, single-channel, 3U PXI waveform generator that offers a direct digital synthesis (DDS) based function generator and arbitrary waveform generation (AWG) functionality within one instrument. Built-in waveforms are available for use with either the DDS or AWG modes of operation and include Sine, Square, Triangle, Ramp up, DC and Noise. The output stage for DDS and AWG modes has different attenuators which are automatically set by the instrument software driver when amplitude and offset voltages are set in order to produce the best possible resolution.
