  •  1, 2 or 4 waveform channels, independent or linked.
  •  40MS/s or 100MS/s 12-bit arbitrary waveform capability using true variable clock architecture.
  •  64K or 1M point waveform memory per channel.
  •  16MHz or 40MHz function generators using DDS*.
  •  Multiple ‘standard’ waveforms including sine, square, triangle, haversine, ramp, pulse and sin(x)/x.

  • Waveform Storage: CF Memory Cards (32MB to 1GB size)
  • Max. Waveforms: 500 per card

The TGA12104 is a 50 MHz arbitrary waveform generator. All TGA1200 series units generate arbitrary waveforms using a variable clock architecture rather than DDS. This ensures that every point in the waveform is replayed exactly as it was defined, the rate of replay being set by the clock frequency.
