Product Tours HelpThese Product Tours are just a structured sequence of web pages. Click the ► button to step through them.
- The navigation buttons have the following functions:
- |◄ takes you back to the beginning of the current tour
- ◄ is the same as your browser back button
- ▲ takes you up a level in the hierarchy
- ► steps forward to the next page
- The drop-lists give another way of accessing the same pages
- shows and hides a map of the structure of the tour with links to each page.
- expands the tour into its own window (only visible when embedded in another page.)

TGxA Series Function Generators: Sweeps, bursts and gated modes
Wide range Frequency SweepPhase continuous sweep is available for all standard and arbitrary waveforms except for pulse.
The sweep range is from 1µHz through to the maximum for the chosen carrier waveform and 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 provide that outputs a pulse at any frequency point within the sweep.
Triggered BurstIn 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 16,777,215 (or infinite). The burst starts and ends at a waveform phase angle settable between -360.0 to +360.0 degrees.
Trigger signalThe 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.
The internal trigger generator is variable between 2mHz and 1MHz with 9 digit resolution.
GatedIn 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.
