1.3.6 Verification
The unit includes a number of tests for rapid verification of the correct functioning of the unit.
Selection of a CW carrier permits measurement of carrier center frequency or phase noise
characteristic. A single-sideband carrier also is available at the operating symbol rate to check I
and Q phase and amplitude balance. When normal operation is again selected, all of the previous
values are restored.
1.3.7 Flash Upgrading Modem Firmware
The internal firmware is both powerful and flexible, permitting storage and retrieval of up to 10
different modem configurations. The CDM-710 uses ‘flash memory’ technology internally, and
new firmware can be uploaded to the unit from an external PC. This simplifies software
upgrading, and updates can be sent via the Internet (using www.comtechefdata.com, Comtech EF
Data’s Web site), by e-mail, or on CD. The upgrade can be performed without opening the unit
simply by connecting the CDM-710 to the Ethernet port of a computer. See Chapter 4. FLASH
UPGRADING for further information.
