Embedded Web Pages
Current IBUC configuration and status information also can be accessed via the
Embedded Web Pages. Although this method does not provide all of the
administrative privileges, such as user creation and deletion, it is the most intuitive for
overall IBUC management.
To access to Embedded Web Pages, open any Web browser and type the IP address of
the IBUC. A login page then appears. After login, the user will have a choice of eight
Web pages with IBUC status, control, alarm information and live charts. Individual
pages are displayed from the selection of the three main drop-down menus.
For more information about the options available on each Web page, see Appendix B,
Embedded Web Pages.
Power Measurement
The Cyber Hardened IBUC 2, IBUC 2e, IBUC 2G, IBUC R and IBUC G are capable
of accurately reading the input and output power for a single carrier in either
continuous signal mode (CSM) or in burst mode. The dynamic range for input power
is from -55 dBm to -20 dBm and for output power the dynamic range is from rated
power to 20 dB below rated power. Each unit is loaded with a detector calibration
lookup table that compensates for detector variations in frequency, power level, and
temperature. The reported power level is then based on the user-requested frequency
and the internally monitored temperature and power level. If multiple carriers are
present, the composite transmit power level is read but accuracy is dependent upon the
actual carrier frequencies, levels, and modulation being used.
The power measurement occurs in the following two ways:
1. Burst Mode
In burst power measurement mode it is assumed that, in normal operation, a
transmit carrier may or not be present due to the nature of burst mode operation.
