On occasion, CEFD may release new software to fix anomalies or add functionality to this interface. Both the CDM-710 and the CDI-70 use ‘flash memory’ technology internally. This makes software upgrading very simple, and updates can now be obtained via the Internet (Figure 10-3), E-mail, or on CD.

    Appendix B. Eb/No MEASUREMENT Although the CDM-710 calculates and displays the value of receive Eb/No on the front panel of the unit, it is sometimes useful to measure the value using a spectrum analyzer, if one is available. The idea is to accurately measure the value of (Co+No)/No, (Carrier density + Noise density/Noise density).
