Appendix A: Options and Accessories

Cable Application Example. The cable connecting the AWG2021 and the user circuit is extremely critical for reliable operation at the maximum clock frequency.

NOTE. Use a coaxial cable with a characteristic impedance of 50 W for all DATA and CLOCK lines.

Keep cables as short as possible.Lengths under 1 meter are desirable.

To minimize signal reflection, carefully process the ends of the cables. Make the section stripped of its outer covering as short as possible and connect the external covering of the cable to the ground for the signals corresponding to each connector. Figure A-7 is the strip length of the coaxial cable.

The strip length has no 50 W impedance.

A 1±meter long digital data cable (part number 012±1408±00) is supplied with this option as a standard accessory. Figure A-8 shows an example of an optional accessory cable and a receiving connector.
