  • Page 207 Options and Accessories Operation Operation when Option 03 is installed is basically the same as the standard AWG2021 operation. When a waveform is not being output, the waveform initial data can be output to the connector. At this time, the clock is not generated. When waveform output begins, the clock is generated and the data is updated.
  • Page 208 Options and Accessories Output Circuit and Output The ECL buffer (10E116) output is connected to the output connector. It must be Waveform terminated with a 50 W resistor at the receiving side (user side). If this termina- tion resistor is missing, the signals do not appear at the output connector. The same is true for the clock output.

  • Page 210 Options and Accessories Application Suggestions Cables. The cable connecting the AWG2021 rear panel output connectors and the user circuit is extremely critical for operation at the maximum clock frequency. Thus, follow these recommendations to obtain optimum performance: H Use coaxial cables with a characteristic impedance of 50 W for all DATA and CLOCK lines.
  • Page 211 Options and Accessories Cable Examples. The AWG2021 with Option 03 comes with a digital data out cable as a standard accessory. The cable is one meter long. The part number for the cable is 012-1408-00. Figure 7–8 shows an example of the standard accessory cable and a receiving connector.

  • Page 218 Options and Accessories Waveform Regeneration In some cases, even a cable that has been carefully made will create transmission distortion. Figure 7–17 shows an example of a circuit used to regenerate the waveform. NOTE. Tektronix cannot be responsible for the infringement of any third-party industrial proprietary rights, copyrights, or other rights arising from the use of these circuits.
  • Page 219 Options and Accessories Option 09 Description This option provides increased internal calculation speed and two additional editors: an FFT editor and a convolution editor. Option 1R Description For Option 1R, the waveform generator is configured for installation in a 19-inch wide instrument rack.
