For visionary developers working to create the next generation of high speed communications technology,the Micram DAC4 Systems deliver truly ultrafast signal generator performance with the highest Analogue Bandwidth in the market.
      Powered by the world record-setting Micram DAC4 UltraFastSiGe™ digital to analog converter, the DAC10001 ,DAC10002 and DAC10004 systems enable researchers and engineers to generate high order complex modulation,such as 32-QAM, 64-QAM,OFDM and advanced 4D formats, at data rates never previously achieved.

Product characteristics

• Single, Dual and Quad differential channels

• 44 GHz Analog Output Bandwidth (-3 dB point) 6 bits vertical resolution

• Rise time (20%-80%) < 7 ps without frequency response compensation

• Ultra low intrinsic jitter (RJ< 100 fs)

• Sample Rate up to 100 GS/s on each channel

• Output voltage up to 1.3 V differential pk-pk

• Flexible, powerful and expandable

Example DAC10001 system output at 64 Gbaud, PRBS-7 sampled at 64 GS/s (1 sample/symbol)

Example DAC10001 system output at 64 Gbaud, PAM-4 showing fast rise and fall times and extremely low jitter. Signal generated with 64 GS/s Sample Rate (1 sample/symbol) and optimized by simple 2-tap FIR @ < 10% pre-emphasis

Example: 50 Gbaud PRBS-7 generated at 100 GS/s (2 samples/symbol) with FIR filtering applied for channel precompensation
