Diamond Line Amplifiers 10 July 2000 33
Configuration Numbers (module + housing)
Diamond Line2 amplifier configuration numbers tell which
amplifier module is installed in which housing. Forexample,
configuration G3A628
D37-CVLG94C1 (variableelements
underlined) specifies the following:
• a Diamond Line2 amplifier module like the example given
on page32 (highest forward frequency of 870MHz, ALSC
pilot frequency of 433.25 MHz, and 10dB station output
tilt athighest frequency) and
• a 9-NHD-15 housing (9-NH15 series housing with deep
lid, as required for element management). For more on
9-NH housing model numbers, see page49.
