XFIN-BLADE-SM
TECHNICAL DESCRIPTION PAGE 49
4.4 ANTENNA REQUIREMENTS
The antenna connections on the Blade are provided with 50Ω female N-type sockets.
These should be tested, by use of a suitable test set, e.g. Anritsu/Wiltron S331A, for good
VSWR (1.5:1 or better) at the Tx and Rx frequencies prior to use.
Mating connectors should be galvanically compatible with nickel outer and gold centre pin
to minimise passive intermodulation.
A minimum of 85dB transmit-receive isolation should be provided by the antenna system
and associated filters.
4.5 POWER SUPPLIES
For type approval reasons, this product should not be operated with un-approved supplies.
The switch mode supplies used in the wall mount and rack mount ancillaries are able to
accept main AC in the range of 100 to 240 V, 50 or 60Hz. The output from the switched
mode power supply to the Blade is +13.6VDC.
Pin 3 on the D-type Power Connector provides protective earthing on the equipment. This
should be connected using heavy duty Green/Yellow earthing wire, capacity greater than
mains feed to equipment, as few bends as possible and an appropriate eyelet tag.
Mains protective Earth should be checked for low impedance (<0.3Ω).
The equipment must be installed so that the IEC connector for the Wall or Rack Mount can
be easily removed and/or the power socket should be readily accessible.
All mains wiring must comply with local wiring regulations.
4.6 CONFIGURATION
Configuration is provided via file download. This is performed via the XBMT Programmer
using a PC connected to the Xfin Control card via its Ethernet port. Files are then stored in
the product in non-volatile memory.
Editing of parameters on a live base station is also possible with a connected PC.
4.7 ADJUSTMENT AND ALIGNMENT
The two RF modules within this product are based upon the RF card of an SRM9000
mobile. The set up and alignment procedures for SRM9000 should be followed. In the
event of a level-3 repair being required, refer to the SRM9000 Service Manual (TSD-
SRM9000-SM) [1].
There are no user adjustments to be made in normal use.
