All Models |
Internal |
Basic arbitrary waveform creation and editing tools are built into the instrument. Arbitrary waveforms can be built-up using insertion of standard waveforms between points, point by point value setting, and straight line drawing between points. |
External |
All TGA1200 series units are supplied with Waveform Manager Plus software for Windows which provides full waveform creation, editing and management. Waveforms are transferred using the digital interfaces or memory card. |

Note that the pulse width and absolute value of the delay may not exceed the pulse period at any time.
Pulse trains of up to 10 pulses may be specified, each pulse having independently defined width, delay and level. The baseline voltage is separately defined and the sequence repetition rate is set by the pulse train period. |

Trigger Repetition Rate |
0.005Hz to 100kHz internal. dc to 1MHz external. Usable repetition rate and waveform frequency depend on the tone switching mode. |
Trigger Source |

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 outputs summed together it is possible to generate DTMF test signals. |
