Multi Channel Sweep (multi-channel units only)

Any number of channels may be swept simultaneously. Amplitude, Offset and Waveform can be set independently for each channel. For TGA124x units the sweep parameters will be the same for all channels. For TGA1210x units the sweep parameters can be set independently for each channel.

Tone Switching Modes:	Gated, Triggered or FSK (see below).
Tone Switching Modes:
Gated: The tone is output while the trigger signal is true and stopped, at the end of the current waveform cycle, while the trigger signal is false. The next tone is output when the trigger signal is true again.
Triggered: The tone is output when the trigger signal goes true and the next tone is output, at the end of the current waveform cycle, when the trigger signal goes true again.
FSK: The tone is output when the trigger signal goes true and the next tone is output, immediately, when the trigger signal goes true again. Using 2 channels with their outputssummedtogether it is possible to generateDTMFtest signals.
