Model SLN2006A MMI Interface Kit
Motorola Model TRN9666A null modem board. Connectors on
opposite sides of the board must be used as this performs a null
modem transformation between cables. This board can used for
10–pin to 8–pin, 25–pin to 25–pin and 10–pin to 10–pin conversions.
Motorola 30–09786R01 MMI cable or equivalent ; used to interface
the LMF serial port connection to GLI2, CSM and LPA debug serial
ports.
25 pin D to 25 pin D serial cable from PC to null modem board.
Communications System Analyzer
The communication system analyzer is used during optimization and
testing of the RF communications portion of BTS equipment and
provides the following functions:
(1) Frequency counter
(2) RF power meter (average and code domain)
(3) RF Signal generator (capable of CDMA modulation)
(4) Spectrum analyzer
(5) CDMA code domain analyzer
The following types of communication system analyzers are currently
supported by the LMF:
HP8921A/600 Analyzer – Including 83203B CDMA Interface,
manual control system card, and 83236A/B PCS Interface for 1900
MHz BTSs.
Advantest R3465 Analyzer – Including R3561L test source unit
Advantest R3267 Analyzer – Including R3562 test source unit
Agilent E4406A Analyzer – including E4432 test source unit
HP8935 Analyzer
CyberTest Communication Analyzer
GPIB Cables
Hewlett Packard 10833A or equivalent; 1 to 2 meters (3 to 6 feet) long
used to interconnect test equipment and LMF terminal.
