TGP3100 Series Pulse Generators: 2 channel Operation

2 Channel screen

Two Channel Operation - TGP3122 & TGP3152

The generators are available in one channel or two channel versions, the latter incorporating two outputs with identical capabilities.

On two channel generators, both channels provide the full performance and specification, along with entirely independent operation when required.

The two channel models represent excellent value for money when compared to purchasing two generators.

Independent Channel Operation

The two channels can be operated completely independently as if they were two separate generators.

Note, however, that the channels share a common external modulation and common external trigger input.

Coupled Operation

The frequencies of the two channels can be coupled such that if frequency of one channel is changed the frequency of the other channel also changes either by a fixed ratio or fixed offset.

Amplitudes (and DC offsets) of the two channels can be coupled such that changing the amplitude and offset on one channel changes the amplitude and offset of both channels.

Outputs of the two channels can be coupled such that switching the output on/off on one channel switches the output on/off of both channels.

Tracking Operation

When in tracking mode both channels behave as one channel. If inverse tracking is selected, both channel still behave as one channel except that the output of channel 2 is inverted.

Relative Phase

The relative phase can be set from -360 degrees to +360 degrees with 0.001 degree resolution. Pressing the ‘align’ key phase synchronizes the two channels with the specified phase offset.
