Universal generators
The TGA1200 series combine a true variable clock arbitrary generator with a high performance DDS function generator and pulse generator in a single instrument.
Wide model range
The TGA1200 series comprises 6 models:
TGA1241 - 40MS/s single channel waveform generator in 3U half rack size case.
TGA1242 - 40MS/s two channel waveform generator in 3U case.
TGA1244 - 40MS/s four channel waveform generator in 3U case.
TGA12101 - 100MS/s single channel waveform generator in 3U half rack size case.
TGA12102 - 100MS/s two channel waveform generator in 3U case.
TGA12104 - 100MS/s four channel waveform generator in 3U case. On multi-channel units each channel can be operated fully independently, or multiple channels can be linked using simple or complex relationships.

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
Capability provided for both standard and arbitrary waveforms. Arbitrary wave- forms are expanded or condensed to exactly 4096 points and DDS techniques are used to allow instantaneous frequency switching.
TGA124x

Carrier Waveforms:
All except pulse, pulse train and sequence.
Frequency List:
Up to 16 frequencies from 1mHz to 10MHz.
Up to 16 frequencies from 1mHz to 40MHz.
Trigger Repetition Rate:
0.005Hz to 100kHz internal. dc to 1MHz exter- nal. Usable repetition rate and waveform fre- quency depend on the tone switching mode.
Trigger Source:
Internal from keyboard, previous channel, next channel or trigger generator. External from TRIG IN or remote interface.
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.
Trigger Generator
Internal source 0.005 Hz to 100kHz square wave adjustable in 10us steps. 3 digit resolution. Available for external use from any SYNC OUT socket.
