Triggering
The GX1110 series provides an external trigger input, offering users the ability to control waveform generation via external trigger events. When operating in the AWG mode, waveform trigger modes include continuous, triggered, gated hold, and burst functionality.
Sample Clock
The GX1110 Series utilizes a PLL, providing a programmable sample clock for the AWG mode of operation. The reference clock is provided by an on-board crystal oscillator, or alternately, an external 10 MHz reference can be used. When operating in the DDS mode, an on-board crystal oscillator source provides a 100 MHz clock source for the DDS generator and associated D to A converter.

| TRIGGER MODES |
| Continuous |
Output continuously generated |
| Triggered |
Output waveform triggered by external or software triggered event. The external trigger signal edge may be a rising or falling edge. |
| Start / Stop |
Output waveform triggered by a trigger signal edge. Waveform is continuously generated until the occurrence of an another trigger edge. The trigger signal may be external or software generated. The external trigger signal edge may be the rising or falling edges. |
| Gated |
Same as Triggered mode except that the waveform is generated for as long as the gate signal stays true (logic one). When the gate signal goes false (logic zero) the output goes quiescent. |
| Gated Hold |
Same as Gated mode except that when the gate signal goes true (logic high) the waveform freezes until the gate signal goes low. |
| Burst |
Output waveform will become active on the occurrence of a trigger edge. The selected waveform is generated for a preset number of cycles between 2 and 1,048,576. Output will then disable. |
