TGP3100 Series Pulse Generators: Waveform Sweep and Burst

Sweep and Burst

As with pulse waveforms, all function and arbitrary waveforms can be operated in Sweep, Burst and Gated modes using either an external trigger signal or the internal trigger generator.

Wide range Frequency Sweep

Phase continuous sweep is available for all standard and arbitrary waveforms. The sweep range is from 1mHz through to the maximum for the chosen carrier waveform. Start and stop frequencies can be set independently.

The sweep can be linear or logarithmic, triggered or continuous with a period between 1ms and 500s. The sweep trigger can be manual or internal from the trigger generator or external from the trigger socket or from a remote interface command.

A marker is provided that outputs an edge synchronous with any frequency point within the sweep.

Triggered Burst

In Burst mode, each active edge of the trigger will produce one burst of the waveform.

The number of cycles in a burst can be set between 1 and 4,294,967,295 (or infinite). The burst starts and ends at a waveform phase angle settable between -360.0 to +360.0 degrees.

Trigger signal

The trigger signal can be manual from the front panel key, internal from the internal trigger generator, external from the trigger-in socket, or remote via a bus command.

The trigger-in socket has a nominal TTL threshold and can be set to +ve edge or -ve edge triggering. The minimum trigger pulse width is 50ns.

Gated

In Gated mode the waveform runs only when the gate signal is true. The start point of the waveform is settable from -360.0 to +360.0 degrees and a the last cycle is completed after the gate signal goes false

All of the options available for triggering are available for gating. The trigger-in socket can be set as high or low for true.
